My daughter and I started going to Dr. Jim Muff about a year and a half ago.  We love this place!  He, his hygienist, office staff, everyone is so friendly.  The prices are very reasonable too.  My 19 yr old daughter got her teeth cleaned this week and went on and on about how nice they were and how pretty her teeth looked.  This is someone I had to drag to the dentist 2 years ago.  So glad we are patients of this office.

Willow Creek Dentistry is as good as it gets! The office is beautiful and the office staff is always welcoming. My wait times have been short. Both Drs Mike and Jim are kind, caring, and competent . I just had my teeth cleaned by Brooke . She was gentle, thorough and very personable, and it was pain free!!! Thank you, Brooke. We have also used Julie. She is great too! If you are looking for a good dental experience, Willow Creek is the place I recommend.

I had the most wonderful experience at Willow Creek Dentistry recently. The dentist was amazing and gentle. The staff went above and beyond what they needed too. I could not find anyone to watch my 2 year old so I needed to bring him with me. The receptionist Tana read books and colored with him while I had my cleaning. I would highly recommend this office to anyone. Very, very kind and comforting office.

I had been neglecting my teeth for 2 years! They started to hurt & I called today as a new patient to see when I could get in. Expecting it to be in 2021…I actually ended up getting an appointment in 3 weeks but got a call today. He squeezed me in at the end of his day. Great receptionist, dental tech & Dentist! The tree outside my room was even decorated with ornaments. 5 stars ⭐️

Courtney G. from Chico, CA (Source: Yelp)


Very impressed with both doctors and all the staff.  Professional and so nice and friendly.  Location was close to home and beautiful office.  Took our 3 boys and it was a great experience for our kids.  I even felt comfortable leaving one kid behind for 20 min while he was getting his teeth cleaned, to get the others to school on time!  I highly recommend them.

I highly recommend going in and be seen by dr. Muff, it’s a great place, nice people as soon as you walk in, assistants are all very nice and try to make your experience the best as possible. Dr. Muff is a very nice guy he knows exactly what he’s doing and tries to do his job the best way possible making you feel comfortable. The work he has done on me has been perfect and I haven’t had any problems with my teeth since I saw him. Best dentist I’ve been to without a doubt.

The BEST DR. In the world!!! Dr. Muff stayed after closing time with his staff to help my niece who had fallen and broke her front teeth after having a seizure. She was having pain and was very scared. He and his staff made her feel very comfortable and safe. He fixed her teeth so she could eat again. What a wonderful man. This Dr is what all Dr’s should be like! I highly recommend him to anyone who needs a kind , Intelligent Dr. you are amazing!! Thank You so much

I am in awe over this dentist office. From past experience I started to have a high anxiety in going to offices so I haven’t gone to a dentist in years. But when reading over their website and seeing their paper work on how they handle patients with anxiety, I decided to give it a try. The staff is very kind, organized, and with COVID they take all the precautions from fever check at the door, mask on when not on the chair, sanitized everything. They work with your anxiety, actually listen and explain what they are doing. Its comforting. They also help with payments and offer care credit. I don’t have much anxiety going here now and its amazing. Thank you guys!

Love Willow Creek Dentistry! Doctors and staff are amazing! I recently had braces put on to correct some mild crowding and need to replace some veneers on my front teeth. Dr. Jim Muff has been very involved in my orthodontic treatment and I cannot wait for the end result! If you want quality dentistry and attention to detail, this is the office to be at!

Lori M. from Chico, CA (Source: Yelp)


I can’t say enough good things about Willow Creek Dentistry! I broke a filling on Sunday and was able to get an appointment to have it repaired within 2 days! I used to require sedation for even the most minor dental procedure but today, while laying comfortably in the chair, I realized that my dental anxieties have completely disappeared! I never thought I’d look at a trip to the dentist as “no big deal” but I guess I just had to find the right dentist! It’s so nice to be relaxed and able to smile and interact with your dentist instead of laying there with your toes curled, fingernails digging into your palm while you sweat bullets, waiting for the next bolt of pain to shoot through your spine! Dr. Muff and his wonderful staff go out of their way to make sure that I am comfortable and well-informed about everything that’s happening in my mouth. He is gentle and patient and doesn’t rush through the procedure before the anesthetic has had time to have an affect. He did a fantastic job on my tooth and other than some lingering numbness, you can’t even see where the tooth stops and the filling begins! The price was more than reasonable (under $300) and they even give discounts if you pay right away. Willow Creek also donated a tremendous amount of dental hygiene supplies to help the displaced victims of the recent Valley fire in Lake County. With nearly 1,300 homes destroyed and thousands of people evacuated, things like toothbrushes, toothpaste and dental floss become that much more appreciated. The generosity of Drs. Muff and staff helped ensure that people could continue with at least part of their daily routine – like brushing their teeth! I’m very happy that Dr. Muff is my dentist and would wholeheartedly recommend his services to anyone who needs quality dental care at a reasonable price! I can say without exaggeration that Dr. Jim Muff is the best dentist I’ve ever had!

After I chipped a filling on Thanksgiving, I knew I needed an appointment at a dentist right away. Dr. Muff was able to see me immediately. He fixed me up in no time. He was very concerned about any discomfort he caused while working on my mouth and made sure I was comfortable. I will be taking my whole family back! Great dentist!

I am a recent transplant to Chico, and finally got around to finding a new dentist here. I’ve had some less than stellar experiences with dentists in the past, so I’m usually not in a rush to find people to poke around inside my mouth. My sister-in-law recommended Willow Creek, and I went in for my first appointment (a cleaning) with them yesterday. For the first time maybe ever, I can honestly say that I’m looking forward to my next cleaning in sixth months. Willow Creek has fantastic customer service! As others have pointed out, the entire staff from the front desk, to the assistants, to the dentists are kind, caring and great and what they do. As a patient, I appreciated the use of technology as an aid to outline the course of action. They also provide a very clear and concise treatment plan which is helpful for deciding what and when you may want to do down the road. Thank you Willow Creek and keep up the great work!

Jeremy H. from Chico, CA (Source: Yelp)


I haven’t been to the dentist in years due to bad experiences of previous dental offices but when walking out of Willow Creek I was surprisingly relieved.. The front desk was very welcoming, every staff member there has a smile on their face and when pulled into the back Dr Muff took the time to go over every X-ray to where I completely understood why I needed the treatment he recommended. He even broke it down for me on what I needed right away & what could wait until my insurance renews in 6 months. Needless to say that I am looking forward to my next cleaning & also any other appointments in the future with Dr Muff.

K S. from Chico, CA (Source: Yelp)


My recent (and first) visit to Willow Creek Dentistry, Chico was for a check up and cleaning. The office is large and pleasant, and the front office staff was inviting. Dr. J. Muff was very thorough in examining my jaw, and teeth. I appreciate the extra care and information he provided. The technician (Kelsey) who took my x-rays was accommodating when I needed a break. Additionally, the lady who did the cleaning (Julie/Julia, I believe) was exceptional. She was gentle, and considerate as well as thorough, and informative. She made me feel at ease, and empowered me to make good oral hygiene habits.

Last Sunday, I broke off a chunk of my front tooth while being manly and lifting heavy things in our cellar. I called Willow Creek Dentistry, who was closed for the weekend, but was directed to Dr. Jim Muff’s on-call number. I doubt anyone enjoys fielding an emergency phone call on a Sunday afternoon, but Dr. Muff was kind and accommodating. He was at home with his 3 small kids while his wife was running errands, but immediately loaded his kids into the car and met me at the clinic within 30 minutes. I was expecting the worst-case scenario of a root canal or extraction, but he was able to salvage my tooth by adhering the broken piece back to its original place. The process was quick and painless, I enjoyed a riveting conversation about unicorns with his adorable 4-yr old daughter, and my tooth is good as new. I can’t speak highly enough of Dr. Jim Muff and the staff. They personify excellence in patient care and are always warm and welcoming to me and my family.

Amanda W. from Tracy, CA (Source: Yelp)


I was searching for a new family dentist recently since relocating and my brother recommended me to this place. I am so glad I listened to him because of how great they treat their patients here. They always make sure you are comfortable and they numb your mouth for everything not like some of the other dentists I have been to in the past. They are really friendly here to highly recommend this place for anyone looking for a new dentist. They also do a very good job and offered to do any touch ups on my crown for free. Its very reasonably priced compared to some of the other places Ive been, HIGHLYYYYYYY recommend seriously you will never want to go to another dentist.

N A. from Chico, CA (Source: Yelp)


Willow Creek Dentistry is amazing! By far the best dental office I’ve ever been to. I was having a toothache and they got me in the same day! Their assistant Katy was very welcoming and down to Earth, and the xrays were a breeze. I wasn’t even nervous when Dr. Muff came in and told me I need a crown because he was so nice and showed me everything on the xrays, then explained the process in a way I could actually understand. A crown in one appointment? Yes! The only thing I was concerned/stressed about was paying for everything because I don’t have insurance, but that was all cleared up when I talked to their finance lady, Paige. The price was lower than I expected and she was able to split everything into monthly payments for me which was so helpful. I’m glad I finally found a high quality office where you can tell the people actually care about you and are willing to help you out as well. Don’t waste your time anywhere else. Willow Creek Dentistry is the best.

Mike replaced, virtually, all of my teeth. It took approximately four months and many appointments. The staff and Dr. were always friendly, helpful and professional. Dr. Muff stands behind his work and if there is a problem takes care of it immediately. The dental work preformed on me could not have been done any better. I would recommend this dental practice to all. Regards: Richard E.

Genna M. from Roseville, CA (Source: Yelp)


I highly recommend Willow Creek Dentistry. I recently moved away from Chico but I still commute to Willow Creek for all my dental care because they are the BEST. They have a beautiful office, they are honest, and technologically advanced. The front office staff is very friendly, the hygienists are amazing, they have a great team of dental assistants and both Doctors do excellent work. I love the way Brooke cleans my teeth, she’s gentle and very thorough. The assistant Katy is awesome! Her friendly energy always makes me feel at ease when having treatment done. If you are looking for outstanding dental care from a caring and compassionate team this is the place to go!

My first appointment was great. The cleanliness of the office was outstanding. The girl who took my X-rays was very efficient and I was so pleasantly surprised at how friendly and professional Dr. Jim Muff is. He answered all my questions to my satisfaction. After going to the same dentist for 30 years, who recently retired, I feel like I’ve found a new “home!”

Sue Horvath-Matheson (Source: Facebook)


It is a pleasure to walk into the facility and be greeted by courteous, cheerful staff who make one feel comfortable immediately. The dental technician is always courteous and efficient. The dentist is very professional and makes diagnoses and procedures as painless and comfortable as possible. I would recommend Willow Creek Dentistry to everyone I know.

I love Willow Creek Dentistry! The people who work there are all friendly and competent. This last visit I needed something more complicated than a filling. Dr Mike is so good. He always does a great job and is careful to make sure that his work is just right and that I’m happy with the result. I think he’s a tooth engineer!!! Thank you Willow Creek!!!

Khana B. from Orland, CA (Source: Yelp)


I have been to many dentists in the area, and this office is definitely the best experience I’ve had!  They are the nicest people and fixed all my dental problems that other dentists couldn’t.  I have had many root canals and crowns, and at this office it was the least uncomfortable.  Dr Muff is so nice, always asking how you are doing and very gentle.  I will never go anywhere else again!

John F. from Chico, CA (Source: Yelp)


This dentist office always is so attentive to my needs. I got a snore guard to stop my snoring and my wife waking me up. Willow creek not only stopped my snoring saved me money and my marriage. I will recommend this dentist office to friends and family. Also the receptionist tanna was very helpful with this process. Keep it up it makes it fun and relaxed to come to the dentist.

Heath R. from Rancho Cordova, CA (Source: Yelp)


I’ve been going to Dr. James Muff for over three years now and continue to have him handle my dental needs despite living in Sacramento, finding a good dentist is worth the drive!   Unfortunately, I don’t floss as diligently as I should and have developed a few cavities over the years; Dr. Muff takes the time to show me on the x-rays where the cavities are and always explains his treatment plan to me before proceeding, this to me is very comforting. Before seeing Dr. Muff my wife complained about tooth pain for several months and saw two other dentists regarding this issue, it was not until we saw Dr. Muff for the first time that he realized the crown was not placed on correctly from the previous dentist, once he made the adjustment the pain subsided.   Keep up the good work Willow Creek Dentistry.

Robert F. from Chico, CA (Source: Yelp)


The two Dr.Muff’s do a really great job. I have been to many dentist but both Dr. Mike and Dr. Jim Muff do a fantastic job. Years ago I had a very sensitive tooth in my mouth. I went to the University of Buffalo dental school and all they did was make it worse. I was hoping I never had to have another treatment on this tooth. Well I did. Dr. Mike Muff did a great job. The tooth that I was so fearful about had no pain whatsoever, he is the best.

I’ve been a patient of Willow Creek Dentistry for the past 4 years. Every employee is extremely friendly, attentive and professional. I am one of those people who has “chicken” written in red on the top of my chart! I can honestly say even with some major dental work, I experienced some discomfort but no pain. Mike Muff is my dentist and him, along with the hygienists, Julie and Debbie are very in tune to your comfort level. I highly recommend Willow Creek Dentistry!

Trevor M. from Blue Lake, CA (Source: Yelp)


I am currently hiking the Pacific Crest Trail (from Mexico to Canada) and have been experiencing tooth pain. I hopped off trail for a wedding and my sister recommended Willow Creek to check out my tooth. I am uninsured so I was hesitant but WC were very transparent about any costs and it only cost me about $300 for a filling replacement. From the friendly and helpful receptionist (Brooke) to the dental assistant (Amy) to the doctor (James Muff), I had a great experience! They worked efficiently as a team and really seem to enjoy their job. The office is very clean and welcoming and everything is organized. I’d recommend them to all!

Briana W. from Chico, CA (Source: Yelp)


I’ve been to numerous offices in Chico and Jim Muff is the nicest dentist by far.  He’s also fair…I was first told I would need a filling and then at the next visit, he said I didn’t need one after all.  It was refreshing to know it was more about the service and less about money.  In fact, considering the work I did have done, I was pleasantly surprised about the price.  And another exciting aspect is that they also do Invisalign there, which is something I’d like to get in the future.  I used Yelp to find this office based on its great reviews, and am so glad I did.  I wouldn’t recommend any other.  🙂

Clayton K. from Chico, CA (Source: Yelp)


After over 6 years of not seeing a dentist due to a horrible experience, I finally decided to go and got a checkup and scheduled a deep cleaning, dreaded it all day and it was amazingly painless and pleasant. Very highly recommended! Great Dr and great staff! Thanks for helping me not fear the scary dentist!

I’ve been a patient of Mike Muff’s for many years now, he’s always concerned about how my comfort level is during procedures, having the latest of equipment, is metculious with color and accuracy of crowns or dental work. He’s in the process of replacing another crown for me and he’s newest “gadgets” made the process even easier. I recommend Mike at Willow Creek to anyone.

Becky P. from Chico, CA (Source: Yelp)


I’ve been a patient of Dr Mike Muffs for many years, he’s always impressed me with his gentleness, his attention to detail, his precision in choice of material, options and color when getting crowns. His willingness to work with my family. and our budget is always appreciated. He’s now stepped up his office with the latest of “gadgets” making the experience of dental work as “enjoyable” as possible. I’ve trusted Mike with my front teeth and he didn’t disappoint, my smile in photos is so much more natural and pretty and I thank his attention to detail! I’d be remiss if I didn’t also mention Julie- she’s a upbeat and gentle hygienist that I also recommend to anyone. It’s a pleasure to get my teeth cleaned by her~

Janine C. from Chico, CA (Source: Yelp)


This is a great Dentist’s office!  We have been clients for about 6 years and have never had a complaint.  The staff is wonderful and the atmosphere is friendly, clean, and comfortable.  They know our names and are great with my husband and me as well as our children.  We like it so much that we moved to Live Oak and we still make the drive to Chico to have our dental visits done here.  Highly recommended 🙂

Carolina G. from Chico, CA (Source: Yelp)


THIS PLACE IS AMAZING!!! I’ve personally have gone through a traumatic experience with dentist’s growing up in the foster care system and I have always feared gong to the dentist.  For one I always felt judge for being in the system and having to go through all these dentists that literally did not care about your smile and stop to realize that some people just aren’t fully educated on the caring of their teeth.  Now that I am all grown up and have private insurance I wanted to make sure I picked a solid, caring, respectful place.  I literally came in walking to this place and spoke with the receptionist, because I had just suffered another traumatic experience at an oral surgeon’s facility.  I asked if they wouldn’t mind me checking their place out and after explaining to them why I wanted to make sure I picked the right dentist office for me, they gave me all the time I needed and I was allowed the opportunity to meet with each dentist.  I was amazed by the kindness of each doctor and how much they wanted my overall experience to be at Willow Creek Dentistry.  All of the staff have been wonderful to me and give me the most respect and always answer any questions I may have.  I hope to be a patient for a long time here at Willow Creek. Once again, this place is amazing! Thank you to the staff at Willow Creek Dentistry and both Doctors who have made my entire experience wonderful. You all are amazing and treat each patient with kindness and respect! THANK YOU!!! -Carolina
