It is always hard to find a new dentist that you can trust your teeth with, but after reading all the good reviews about Dr. Lamise Kassem I’ve decided to check it out. Upon entering the office, the receptionist was warm and welcoming. Dr. Kassem was very professional and she helped me right away with my tooth problem. Most dentist I have been to would try to tell me that I need to do this or that so that they can get more money out of my pocket, but not Dr. Kassem, she went straight to the problem and took her time helping me. She was very gentle, and while working on my tooth she made sure that if I feel any discomfort to let her know.
After getting my tooth fixed I was worried that my retainer would not fit because of the crown placed over my molar, but Dr. Kassem was understanding and offered to help remake my retainer if i needed to.
All in all, Dr. Kassem and her team was very warm, friendly, and welcoming.

My husband and I have been patients of Dr. Kassem for over 10 years! She is professional and caring. Always looking for the best interest of her patients. Our kids now also enjoy their 6 month cleaning with her too! Her office is very clean and her staff is also nice.

Irene H. from Colorado Springs, CO (Source: Yelp)


My husband and I have both appreciated Dr. Kassem’s dental skill and the welcoming atmosphere she creates in the office. She has now expertly repaired work for both of us that was done poorly by a previous dentist. No one likes to go to the dentist, but Dr. Kassem and her staff are pleasant to be with and we rest confidently in her professionalism and skill.

Bill B. from San Francisco, CA (Source: Yelp)


Dr Kassem ranks up there with the best dentists that I have had in my 60+ years.
I had never had a dentist check me for dental bone loss before Dr. Kassem.
The dental cleanings are the most modern I have ever had.
I moved to So Cal Nov. 2017 and  looked up Dr Kassem to treat a loose crown I was experiencing.  She ensured me that there was no further damage/problems and took care of it immediately.
Overall her and her staff are very professional and knowledgeable and make you feel at ease.

Jack C. from Laguna Woods, CA (Source: Yelp)


We just relocated from the Midwest and, as a person with a history of major dental work, I needed to find a dentist who was both capable and easy to work with.  Dr. Kassem filled the bill perfectly.  She is engaging, runs an efficient and friendly office, is very careful to do painless work,  and was able to take me the first time as an emergency case on very little notice.  I’ve had experience with a number of dentists over the years, and I’d put her at the top of the list.  Also, it’s nice to know you have a good dentist BEFORE you need work.

The staff and Dr. Lamise are very professional and welcoming. So far, all the times I have visited their office, I’ve had a great experience. Today, my six month cleaning was done very good and I felt no pain or discomfort. The hygienist made me feel at ease and comfortable. Every time my children go, they come out happy and satisfied. I highly recommend this dental office. It’s very clean, organized, and pleasant to visit.

K. C. from Corona, CA (Source: Yelp)


Dr. Kassem is a great dentist. She’s very personable and does great work. Her staff is also very nice and welcoming. I make the drive here all the way from Corona because she’s that great of a dentist. Her office is clean and nicely decorated. I highly recommend her.

Rosaida B. from Garden Grove, CA (Source: Yelp)


Dr. Kassem is great. The office is clean and very welcoming and her staff goes above and beyond their work and so does the doctor. I’m glad my friend referred me to her and I trust Dr. Kassem to take care of my dental needs from now on. Thank you so much Doc!! You’re awesome.

Dr. Kassem and her kind and courteous staff have actually cured me of my fear of dentists. Her chair-side manner, smiling face, and non-condemning attitude make it a pleasure to have her as my dentist. Always excellent service. Tops in her profession. Would recommend her to one and all looking for excellence in dentistry.

I have been seeing Dr. Lamise for well over a year and will not visit any other dentist office but hers. Her care and attention to any issues are handled professionally and will make sure you are well during cleanings. I just had a smooth cleaning after over 6 months and will continue to come here.

Jacob H. from Huntington Beach, CA (Source: Yelp)


OMG Wow what a great experience. Such a friendly and amazing staff. I had 3 cavities filled(was supposed to be 5) and it was a pain free experience. I was afraid I was gonna tap out after 3 from the pain before i sat in the chair. They want you to leave satisfied with their work. I used to be scared of dentist visits, not anymore! I’ll be back every 6 months for check ups and cleanings and will refer all who are looking for a new dentist.

Renee Cochran from Tustin, CA (Source: Yelp)


Yesterday i had am emergency problem with a tooth. (A different dentist) had performed two crowns next to each other. I call early Saturday to see if she could see me to relieve the excruciating pain i had suffered all night. Her office was beautiful and welcoming. She said that my crowns were not put in correctly and there was a gap between the two leaving space for infection. She adjusted my crowns and assisted my painful tooth with ease. Very caring and compassionate. Shes my new dentist.

Tonia W. from Anaheim, CA (Source: Yelp)


I love Dr. Kassem and her staff. Not only are they good at what they do, they won’t try and milk you for every dime you have. Dr. Kassem is conservative when it comes to dental work by informing you of what you need only. She is funny and kind and My whole family has been seeing her for years. I always carry a few of her cards because I seem to always run across people who dislike their current dentist. Consider this your virtual card – go see her already!

Veronica P. from Santa Ana, CA (Source: Yelp)


Great office, my boyfriend, daughter and I love coming here. Everyone is nice and friendly. I definitely recommend Dr. Kassem.

Nancy S. from Orange, CA (Source: Yelp)


Still a great dentist and a beautiful office. We have been coming to Dr. Kassem for a few years and my family loves her. She is a great dentist and her practice employs a great staff. We will continue to come her for as long as she is in practice around or nearby. We might even drive as far as an hour. So happy to have found her and we appreciate the care her and her office give to our family.

The best dentist by far! It’s been so long since I’ve been to a dentist and it’s mostly because of fear…of having a doctor who cares more about money than the patient. NOT DR. LAMISE! from my first visit, she instantly came across as a genuine person. She definitely cares about her patient more so than money. I left her office feeling SO good about myself! it’s so rare to find a good, genuine doctor like her. My first time ever to write a review about a business, because the great feeling I have from the services done by her is worth my time! TOTALLY RECOMMEND!! Oh, and the office is beautiful and clean! Great, friendly staffs too. =)

Amanda B. from Orange, CA (Source: Yelp)


Dr. Kassem and her staff is amazing! I was able to get my checkup and cleaning in 45 minutes! It was nice to not have to wait nor be treated as just another patient, they actually took the time to get to know me and make sure I was comfortable. Dr. Kassem is my new go to dentist.

Natassia Kirk Smith (Source: Facebook)


We finally found a new dentist near us! Dr. Kassem and her staff were so welcoming, warm, and caring. We hadn’t been to the dentist in a few years and they didn’t make us feel bad for it or lecture us about the importance, instead they made us feel comfortable and relaxed. Dr. Kassem was understanding that we couldn’t spend (a large amount of money) fixing everything all at once and helped us come up with a plan of attack. It was a great first visit and we will be back soon and regularly!

When you love clean teeth but have not gone to the dentist in while??? I knew I had to suck it up and go to the dentist as brushing and flossing weren’t going to thoroughly clean what I can’t brush away.  I didn’t want to choose just any dentist closes to my house (which may have led to me not having gone to a dentist in a while due to bad experience) so I made sure I did some research prior, and I’m very glad I did!

Dr. Kassem made me feel at ease and I was very comfortable in her care.  She did not push me for any unnecessary procedures nor did she try to push products. I was shown X-rays of my teeth and explained what needed to be done and what could be done better to prevent complications.  I scheduled my 2nd appointment 1.5 weeks after my first (for a necessary procedure) and was in an out in about 15 minutes!

Staff are great as well! Amanda, the dentist assistant, as well as another front desk girl (forgot her name) were polite and pleasant.

I have already recommended Dr. Kassem!

Melissa S. from Central LA, Los Angeles, CA (Source: Yelp)


Dr Kassem and her staff are awesome! My friend recommended her to me after I had gone through 4 dentists that were constantly trying to upsell me on unnecessary treatment. Dr Kassem has a very conservative approach and doesn’t push unnecessary treatments. However, when there is an emergency, you’d better believe it that she knows what to do! My daughter had some bad work done by a previous dentist and Dr Kassem was right on it! She’s honest and that’s what you want in a dentist. She provides honest diagnosis, quality preventive care, and a clean and friendly environment. Oh, did I mention she takes HMO! Yet I get treated like I’m a PPO client. Everyone I’ve referred to her comes back happy and has changed her to be their dentist. I can’t say enough good things about Dr Kassem and her staff.

I’ve been a patient of Dr. Kassem for many years. She has always treated me with compassion. always available for any unscheduled emergency treatment. She is very gentle with working on dental my needs. Her chair side dental professionals has been trained thru her expertise and does pursue the same experience to me. I’ve seen many dentists through my lifetime, and have never felt this comfortable. Thank you Dr Kassem & staff

K. Shahin from Grand Terrace, CA (Source: Healthgrades)


I love this place, although I have fear from dentists and dental procedures. The minute I walk in the office, I just feel so calm and at ease. Dr. Kassem and her staff greet me with a big smile. Dr. Lamise cares about her patients and informs her patients with details of procedures. Also she has a very educated and welcoming staff. I highly recommend this office to everyone and I’m sure you will not regret it.

Christine Enos (Source: Google)


Dr. Kassem has always been amazing with us. She is so personable and truly shows she cares about our teeth. The staff is amazing and took every precaution to make sure everyone was safe and protected during our visit. We highly recommend Dr. Kassem.

Yesenia A. from Tustin, CA (Source: Yelp)


This is by far the best dental office I’ve been to aside from my previous doctor. Dr Lamise was working the reception area and was friendly and welcoming. Her staff is very knowledgeable and friendly as well. I felt I was in good hands- procedure was quick and painless. She is a good dentist and treats everyone with respect and is honest about her recommendations. I enjoy my visit because she didn’t try to sell me anything crazy and appreciate her honest opinions.

Peter H. from Fullerton, CA (Source: Yelp)


I highly recommend Dr. Kassem and her staff. They are friendly, fun, and welcoming. Most importantly they are honest. They knew I have (not a good) insurance and didn’t treat me as a second class citizen like my last dentist at (a different dental office). Dr. Kassem thoroughly exam, clean my teeth, and inform me things I should watch out for. She didn’t try to sell me something I don’t need like deep cleaning or pressure me into something with a fear of gum disease if I didn’t preform the procedure. I am only afraid of forgetting to floss regularly before my next appointment with Dr. Kassem.

Kathleen A. from Orange, CA (Source: Yelp)


We have been clients of Dr. Kassem for many years and have been very pleased with our care. The office presentation is professional, organized, clean, and friendly. Dr. Kassem is very knowledgeable about her field and explains any situation readily and completely. Dr. Kassem and staff always remember who we are which is so nice. We recommend her highly to any of our friends who are looking for dental care.

Diane from Orange, CA (Source: Healthgrades)


Dr Kassem has renewed my faith in dentistry. I hadn’t gone to a dentist in years because of multiple bad experiences. I was referred to Dr Kassem by a friend who was uninsured and needed a lot of work done. She had such great things to say that I decided to try her out. I’ve had filings, a crown, and a cleaning done. She did an excellent job and was very patient with me. Plus, she has a great personality. I highly recommend her!

Narmin S. from Glendale, CA (Source: Yelp)


I drive an hour to go to (doctor Kassem’s office) because I refuse to have another dentist work on my teeth. Dr. Kaseem is amazing.  She takes her time with her patients and recommends the best procedures catered to the specific needs of her client. I have always had a fear of dentists and she doesn’t scare me! 🙂 Also, her assistants are always so pleasant and respectful. I have found my dentist for life. Check her out if you are looking for a new dentist.

Krys G. from La Mirada, CA (Source: Yelp)


Dr. Kassem is the best. She’s super professional while making you feel comfortable at the same time. Visits with her and her staff are quick and painless. The office is in a great location and beautifully decorated. I went from one insurance to another and I was so relieved  to know that I could stay under Dr. Kassem’s care. My mom and brothers are her patients now too. I can’t recommend her enough!

Kim L. from Huntington Beach, CA (Source: Yelp)


I have been with Dr. Kassem for years and have followed her to every new office.  I am scared of getting dental work, and she is so gentle and patient with me.  Her staff is extremely friendly and welcoming.  Dr. Kassem provides many options for your personal dental care and will create a plan that works in your budget and insurance.  I would highly recommend her to anyone who is nervous about getting dental work.  She is the BEST!

Tristan S. from Orange, CA (Source: Yelp)


Dr Kassem and her staff are fantastic. I’ve been a patient here for 3 or so years now and every interaction is top notch.

Nancy Shouga-Savage (Source: Facebook)


Dr. Kassem is an amazing dentist. From the moment I’ve stepped into her offices I’ve felt comfortable and like family. My kids ages 5,4 and 1 are also patients of hers. They love going and getting their teeth cleaned by the nice assistants. Best dental office I have ever been to!
