First of all, today is SATURDAY, July 4, 2020. Today I called Valencia Children Dental Group because my son woke up with dental pain and immediately Dr. Mulcahey called me back! Wow! What service! Not only did she spend the majority of the day texting, calling and assisting me to develop a treatment plan for my 5 year old son, but she did so with a kind, loving and caring approach with my son’s best interest in mind. I am so grateful that she spent the majority of her day attending to my son despite her office being closed on the 4th of July. I would NEVER go to another dental office. Valencia Children’s Dental Group is the best for your child’s dental health and well being. My son is feeling 100% better thanks to Dr. Mulcahey’s help! Thank you so much.

We have been going to Valencia Children’s Dental for a few years and have always found them to be extremely friendly, helpful and professional. Every person in the office works toward the same goal of truly caring for patients. Even with my child who was extremely anxious about a small cavity that needed to be filled, Dr. Mulcahey and her staff were patient, caring and gentle with him while they worked on him. Everything about this office shows how much they truly care for their patients!

I was in a bind and needed to have my son seen as soon as possible, when I called Valencia Children’s Dental Group they were very understanding and accommodating and were able to get my son in the same day. And once we got in, Dr. Kim made him feel comfortable and treated him like royalty. I have referred many people to Valencia Children’s Dental Group, all of them have been very happy with their service and my family will continue to go see Dr. Kim and Dr. Mulcahey.

I started taking my kids here in 2003 and we could never go anywhere else.  Both Dr. Kim and Dr. Mulcahey are very kid conscious and they make going to the dentist a pleasant experience.  Even though they’re out of network for us, we still go here and pay the extra $$ because the peace of mind we get here is Priceless!  I feel so comfortable bringing my kids here that even I decided to get braces and have Dr. Mulcahey getting my teeth looking great.  The place is ultra kid friendly, the hygenists are friendly and gentle, and of course the dentists are awesome.

We have found the best dentists and orthodontist in Valencia! From Dana and the front desk staff to the dental hygienists to the doctors, they are amazing! I can always get our daughters appointments at a time that works for their school schedules. I even called this morning to see if we could come a bit later than our scheduled appointment and they made it work!! Honestly can’t say enough great things about them. Oh and the brushing station is always the first thing my girls do when they walk in the door!!!

Jessica K. from Santa Clarita, CA (Source: Yelp)


I am so glad I found this place! I had been dreading my son’s first dental appointment, but everyone in this office was AWESOME, and my son was SMILING and HAPPY the entire time he got his teeth cleaned! Everyone was so friendly, and they genuinely seemed happy to be there. Plus, Dr. Canooga (I hope I’m spelling it right!) was so nice and supportive when I told her my son is a vegetarian. I get weird responses from people sometimes (including people in the health field) when I tell them that, and I have to explain that it’s a healthy diet if planned properly, and blah, blah, blah. What a relief to have someone actually be supportive of my child’s diet for a change (yes, he chose to be vegetarian himself). Anyway, I highly recommend this office, and my son actually asked me, “Mommy, when do I get my teeth cleaned again? Tomorrow?” And he was disappointed when I told him it would be a while before he would need it done again!

Great experience yesterday with this place.  Very knowledgeable and took great care of the patient I took in to get a filling.  Staff on hand was very courteous and patient.  They have rooms geared for the kids with playstations and tv’s in the ceilings so the kids can watch cartoons and not think about their teeth!!!  Most important Parents are allowed back with their kids and aren’t strapped down to the chair like Hannibal Lector!!!  4 Thumbs Way Up to this place.

We have been coming here for several years and love it! The office is always clean and the staff always very friendly. As a healthcare provider myself, I appreciate how they tailor the visit to my daughter, ending each visit with a written care plan to take home. The office is focused toward kids from TVs on the ceilings to distract during cleaning, to the decor, all the way to the way they talk to the kids- calling them ‘sugar bugs’ instead of ‘plaque’. Overall this is a great environment to help kids enjoy oral hygiene instead of fear it! I throughly recommend Valencia Children’s Dental!!!

Highly recommended!!! I can’t write enough good things about this place!!! First of all, I was looking for a good experienced Peditrician since my son it’s only 18 months and the Dentist here was amazing. Donna at the front desk it’s super sweet and she kind of made the sale for us to choose this place. They made his experience less scary and took the time to explain all the necessary steps to his dental treatments. My son had a good time and was really excited to get stickers and fire track at the end. Loveeeeeeeeeed it!!!

Lena C. from Santa Clarita, CA (Source: Yelp)


Absolutely love the place !!! All the doctors, amazing friendly very helpful ladies if the front desk and entire staff crew!!! Been going there for over 5 years and will never look for another place for my children. Very clean inside and beyond kid friendly.. not once my kids felt uncomfortable or scared… always excited to get feee goodie bag with toothbrushes and of course stickers!

2012 review: I drive an hour to bring my kids to the dentist here. Dr. Kathy was a friend from college, and I only took my daughter because she was having such a hard time with other dentists (she’s always been flighty about doctors and needles). She loved it so much that I started taking all 3 of my kids. That was 2005. I recently suggested to my sons (6 & 8) that maybe we should switch to a dentist nearby. My 8-year-old protested and my six-year-old was in tears. They love it, and our kids’ teeth are doing much better after their care. 2016 update: My sons are now 11 and 13, and they still prefer to drive all the way to Valencia to come see Dr. Kathy. The staff are always great– friendly, caring, and on top of all the details. They’re a pleasure to do business with!

We love going to see Dr. Mulcahey! Her office staff is friendly and always considerate to try and schedule my children all at the same time. The kids love the fun office atmosphere, the kind dental hygienists, Dr. Mulcahey herself, and the fun prizes they get for no cavities. And I truly feel like my children’s teeth are taken care of in the best manner possible. Since it is pretty clear from their smiles that my kids will be needing braces, I am also SO thankful to be at a dentist office that I know can care for both their dental AND orthodontic needs all the way through high school – it makes life just that much simpler!

Mark F. from Valencia, CA (Source: Yelp)


Just took our 5 year old granddaughter for her first check up. She’s was quite nervous to go. After her visit I asked how her visit was and she enthusiastically said “Awesome!!!” Here’s her review: The best thing about the dentist was the X-rays – it was very comfortable and they gave me a princess pillow. They were also very careful. I liked the fish tank and the play area. Dr. Mulcahey was very nice, sweet and perfect for me! Don’t think she’ll ever be worried about going to the dentist again!

Silvia N. from Saugus, CA (Source: Yelp)


I have been taking my children here since 2000/01 and it is always a pleasure to go. My son, when he was 5, had a big procedure done and it was a breeze. Now 10 years later his teeth are in great shape thanks to their care. My daughter is getting great care as well. We just recently went in for her cleaning and is cavity free. Its always a pleasant experience. The dentists, hygienists and the ladies at the front are all very friendly. I wish I could say something bad just so no one else goes…appointment times would open up. 😉 Joking aside, VCDG is a great place to take your children for dental care.

Scott M. from Castaic, CA (Source: Yelp)


The staff is wonderful at this dentist.  My kids are excited every time I tell them we are going dentist. We have multiple kids and they are able to get them all in at the same time.   It is very kid friendly but they also have a keurig machine in the front (for the parents) just in case you have an early appointment.

My two girls have been coming here since their very first dental appt. when they were little. They are now 17 & 21. Both had braces as well. I can’t say enough about how wonderful & warm the entire team is consistently! Dr. Kim & Dr. Mulcahey are the absolute best!

Strader D. from Santa Clarita, CA (Source: Yelp)


My kids loving going to the dentist.  They think of the staff at Valencia Children’s Dental group like family.  My 15 year old who has braces loves Dr. Mulcahey!  My other 3 think the video games, t.v.s. , games, stickers and no cavity club are so much fun.  I highly recommend this office for their professionalism, family atmoshpere and no long waits

Bouseh B. from Santa Clarita, CA (Source: Yelp)


I’ve been taking my kids to Dr. Mulcahey for nearly 9 years.  I can’t imagine going anywhere else.  Everyone from the front office to the dental hygienist are so kind, friendly and caring.  They are very knowledgeable and have all the latest tools. They will make your child love going to the dentist.  I would even go to this office even my insurance didn’t pay for it, that’s how much I like everyone at the office.

My family and I LOVE this dentist office. It is everything you need. Clean, convenient, wonderful caring dentists, orthodontist, and hygienists. The only place I’ve ever been to that makes going to the dentist as positive as it can possible be. Also my daughter has really learned to appreciate and take care of her teeth, and even aspires receive the cleanest teeth award and have her photo on the wall. Hey, if it keeps her taking good care of her teeth and flossing religiously, I’m all for it. Everyone there is so patient and kind too. My daughter was really nervous about having her teeth cleaned during the pandemic, so they really talked with her and explained everything so that she could feel totally comfortable and at ease. I could go on and on about how wonderful this office is. If you live anywhere in Santa Clarita, this is your place.

Kristyne B. from Castaic, CA (Source: Yelp)


There is not enough room in this little box for all of the wonderful things I could say about Dr Mulcahey and her staff. Our previous dentist was not good with children and we switched to Dr Mulcahey at the recommendation of a friend. That was about 10 years ago! My children have both gone through braces and many regular checkups with her since then.  They love her and her staff! She gets to know each and everyone of her patients and makes them feel completely at ease. Her office is set up perfectly for kids and she takes the time to explain everything to them and makes sure they are comfortable with the exam, etc.. Her staff is just as friendly and professional as she is. I highly recommend Valencia Children’s Dental Group!!

Janet H. from San Fernando, CA (Source: Yelp)


This office is the most kind and caring group of people I have ever had the opportunity to work on my daughter’s teeth. Whatever billing issues Christina had she must had not been listening very well or wanted something for nothing. They have cared for my daughter with her braces like she was their own child. WE LOVE YOU ALL AT VALENCIA CHILDREN’S DENTAL GROUP!!!!!!!   Thank you for being so kind to us. I tell everyone I know you’re the best!!!! You can tell everyone is happy to work there too. Love, Dereka & Janet Henderson

My kids have been here since they were little and have enjoyed the whole team. They are a great bunch of people that are sweet, respectful and upfront with what needs to be done. The office staff is always ready to help when I need extra paperwork for insurance or a copy of records. Dr. Kim and Dr. Mulcahey are the best!! In addition, there is always coffee available for me while I wait for my 3 kiddos

I was so happy with my experience at Valencia Children’s Dental. My 4 year old daughter was a little nervous, not knowing what to expect, and they quickly put her at ease and showered her with lots of glittery items to make her happy and keep her distracted. The staff was incredibly friendly. They have a great waiting room, filled with toys and even a variety of Keurig options for Mommy and Daddy. We’ll be using them for years.

Love, love everyone here!!! Everyone is friendly and professional and we feel welcome the second we walk through the door. Dr. Mulcahey and her team always makes the kids feel comfortable and safe. My boys love them. I love the fact that Dr. Mulcahey is also an Orthodontic. You get the best of both worlds in one place! Two of my boy’s have had braces and we’ve had a couple emergencies. The staff was wonderful, they worked with me for a payment plan I could afford. I highly recommend Valencia Children’s Group!

Clare P. from Santa Clarita, CA (Source: Yelp)


My children have been going to VCDG for 10 years and I have never considered going anywhere else! They really know how to do pediatric dentistry. Everything is geared towards the kids and parents having a great experience. The staff at the front desk is the best I’ve ever encountered in a doctor’s office; they make us feel like family. I frequently have to reschedule appointments and it is never a problem. They understand the life of a busy parent. The hygienists and dental assistants are gentle and friendly and everyone works together as a team. Dr. Mulcahey has always treated my kids as if they were her own. She and Dr. Kim are warm, caring and very professional. It is such a bonus that they do orthodontics also. My 14 year old son just got his braces off and it was so fabulous being able to take him to the same office and the same doctor! His teeth are now beautiful!! I can’t say enough good things about VCDG. A trip to this dentist office is never dreaded, always anticipated!

Marie-Claire E. from Ashland, OR (Source: Yelp)


I went to Valenica Childrens Dental Group to Dr. Mulcahey growing up and my two younger brothers continue to go here for Dentistry and Orthodontics. It a great children’s dental. I had Dr. Mulcahey for years as my Orthodontist, she left my teeth absolutely beautiful and I am now so proud of my smile. It did take a very long time to adjust my teeth but that’s braces for you. When I got braces here years ago, actual braces were really my only option for the price range we had available to fix my teeth but my younger brothers got them much later and Invisalign became a much more affordable option in that time. Dr. Mulcahey gives both options. The dental hygienists are friendly, thorough, and gentle. It very much smells like the dentist. Like laughing gas and disinfectant, not a pleasant smell but very dentisty. I suppose not out of the ordinary. I really don’t like their choice in television that constantly plays. I don’t like Disney channel but I suppose that is more of a preference that doesn’t have to do with dentistry still I don’t want to be forced into watch the Disney channel while getting my teeth cleaned.

From the moment I called to book my daughters appointment to the moment we left the appointment I was completely impressed. The staff is amazing and friendly, Dr. Kim was amazing at explaining to my daughter in a way a 3 year old could understand exactly what was happening play by play. I was nervous how things would go today as my daughter is scared of the doctor due to some medical issues earlier this year, but you wouldn’t know that by this appointment. I’m so grateful for the time and care they put in to this appointment and I am confident they will continue to do so. Loved the “tooth brush station” complete with toothbrushes, toothpaste, and mouthwash for the kiddos, the photobooth set up for your after photos, and the prizes they give for doing a good job. So many little details that definitely didn’t go unnoticed!

Tony Q. from Valencia, CA (Source: Yelp)


There are no words that will do justice to the perfection that we experienced at Valencia Children’s Dental group.  The staff are a team of absolute pro’s who make it a pleasure visiting the office.  They are accommodating and courteous.  The office space itself feels like you’re hanging out in your own living room,  the fish tank is especially awesome.  Dr. Mulcahey is a virtuoso with her craft.  She absolutely transformed my son’s smile.  And in such a short time!!    Let Valencia Children’s Dental be the end of your search for any and all dental or orthodontic needs.  Thank you Dr. M. and everyone at VCDG.

Valencia Children’s Dental group has been so great to my son, now 8 years old. He has been going to Valencia Children’s Dental since he was 2 years old. This dentist is actually out of network for my insurance but I would not trade it for any other!!! They staff is wonderful, always friendly, polite, patient, and accommodating!!! They offer a no cavity raffle as a motivation to keep the kids interested in their oral hygienes. My son actually won once and got a gift card to toys r us, and his picture up for a year which my son LOVED! I am excited to start taking my other son who will be 2 in October. Dr. Kim and Dr. Mulcahey are GREAT!! I’ve recommended this dentist to many and I will continue to do so!

I was referred to this office by my daughter’s regular dentist because she would not allow the shot for her fillings and it started to get traumatic for her. I was nervous after I read the reviews on Yelp, but decided to trust the recommendation and I am SOOOOOOOOOOOO GLAD I did. The Valencia Children’s Dental Group just knocked my socks off. My daughter, who is only five, was very antsy about getting the gas, and she even started to cry but Dr Kim calmed her, and gained her trust very quickly. My daughter did not flinch once, even when they gave her multiple shots for her fillings, she didn’t cry… she was so at ease. I was in absolute awe! Not only that, but they were very clear from the beginning what the cost of the fillings would be and gave me a break down and a print-out per visit. They were personable and friendly, and my daughter now declares that they are her favorite dentist. I am very happy with everything about the office and I highly recommend them to anyone, especially if you have young children.

I have four children. My children have been seeing the Dentist, Dr. Kim since they were little ones and I/they have always had great experiences with every aspect of Valencia Childrens Dental. In fact, one time when my daughter was about 6 years old she asked me, “Mommy, do they do birthday parties here?” When we have gone in for appointments we have never waited more than 10 minutes. In fact usually its just a few minutes before they are called to the chairs. The nurses are knowledgable and very sweet with the kids. The hygienists are thorough and also very patient with the kids, showing them places they missed and areas they need to work on. I know they have repeated their spiel a million times but it never feels that way. The Orthodontist, Dr. Mulcahey, is as good as it gets. Period. I have had 2 daughters complete their orthodontic care and my third daughter is in braces currently. We are looking forward to seeing the beautiful results she gets on her smile. Dr. Mulcahey is very knowledgable and accurate on the timeline the braces need to be on the results have been perfect. Additionally, the cost of the orthodontic and dental care has always been very clear. The billing to the insurances companies and me has always been done in a timely manner and Debbie, in the billing department is on top of things.

Andrea F. from Santa Clarita, CA (Source: Yelp)


I’ve been taking my four children to doctors Mulcahey and Kim for seven years for both dental work and braces.  The doctors and their staff are always willing to go the extra mile for each patient and give them the individual care they need.  Strongly recommend!

Thank you so much for fixing my son, Bodhi’s, teeth!!! He went to school with a chipped tooth from over the weekend and everyone was shocked the next day when he came back looking like nothing had ever happened ❤

Karen G. from Culver City, CA (Source: Yelp)


The doctors and staff at Valencia Children’s Dental Group are fantastic.  The practice is set up to be comfortable and inviting for kids – certainly makes a trip to the dentist more attractive than it was when I was young!  Both Dr. Mulcahey and Dr. Kim are professional and friendly, and very knowledgeable about dental health.  The hygenists are great and do a good job relating to the kids, no matter what the age.  We’ve been going here since the kids were very young and yes, we drive quite far, but we will keep doing so to receive the level of care we get here


Our practice specializes in dentistry and orthodontics for children and teens. Dr. Kim is a pediatric dentist who completed her pediatric residency at UCLA School Dentistry in 1994. Dr. Mulcahey completed a dual pediatric and orthodontic residency at UCLA School of Dentistry in 1995. Together with their wonderfully dedicated staff they are committed to providing your child with a stress free, fun dental and orthodontic experience. We offer treatment with Nitrous Oxide upon request. We work in partnership with the UCLA anesthesia team for our more involved cases. We moved into our new facility in 2008 and we offer the latest technology in dentistry to your child. There is a No Cavity Club and the kids are offered prizes after every appointment. Kids love coming here. We are often told that kids remind their parents when it's time to come back! Dr. Kathleen L. Mulcahey was born in Pomona, California, and grew up in Claremont. Her passion for orthodontics began in high school. After begging her parents for orthodontic treatment, she got braces. As she watched her smile improve, she found herself fascinated with the various techniques that the staff was using to make things happen. Once her braces were removed, she was shocked with how much better her adjusted smile made her feel. She got excited that as an orthodontist, she might be able to have a positive effect on how people viewed themselves, and that’s when Dr. Mulcahey decided to pursue a career in orthodontics. Highly educated, Dr. Mulcahey obtained her Doctor of Dental Surgery degree from the University of California, San Francisco. Toward the end of her time in dental school, she realized that she enjoyed working with children. When the opportunity to be a resident in the combined program for Pediatric Dentistry and Orthodontics at UCLA, Dr. Mulcahey jumped at the chance. She has provided the highest quality pediatric dental care and orthodontics since 1998. Dr. Mulcahey stays current with the latest advancements in her fields by maintaining memberships in many professional organizations. She is a member of the American Dental Association, California Dental Association, the San Fernando Valley Dental Society, the American Academy of Pediatric Dentistry, the California Society of Pediatric Dentistry, the American Association of Orthodontists and the Pacific Coast Society of Orthodontists. To give back to her community, Dr. Mulcahey volunteers with the Smiles Changes Lives program by providing orthodontic care to underprivileged children. In her personal life, Dr. Mulcahey is married to her wonderful husband, Butch, who is a brilliant engineer. Together they have three lively and loving boys: Joey, Stephen and Michael. She finally got her girl when the family got their dog, Keelie, a Finnish Spitz. With three boys, Dr. Mulcahey spends a lot of time managing homework, sports practices and games, household affairs and such. But she loves music and currently sings in the choir, sings in the worship team and is the Director of Children’s Choir at her church. She also enjoys reading, walking and getting together with friends and family.
