He is a tooth guru! I trust him fully to give great care, he is extremely experienced and good at his job.

The dentists themselves, Dr. Tan and Dr. Mattingly, are absolutely wonderful. Their care has always been professional, thorough, and welcoming, which is why I stayed with this clinic and spent around $8,000-$9,000 here over the past year. Unfortunately, my experience with the office administration has been very different. I was told by Erin that my benefits would be restarting in July 2025. It wasn't phrased as "I think" or "I believe" -- it was stated as fact. Trusting that information, I scheduled my cleaning. Later I found out this wasn't true, and have to pay for the visit fully out of pocket. When I raised my concerns, instead of hearing empathy or even an acknowledgment of the misunderstanding, I felt dismissed. Erin has consistently come across with attitude, and when I received a voicemail and phone call from Arlene, the tone felt accusatory rather than understanding. Even a simple "I'm sorry for the mix-up, unfortunately that wasn't the case" would have gone a long way. I understand the balance is my responsibility but it would've been nice at least knowing that leadership will review the previous verbiage used so the team can avoid similar misunderstandings for future patients. Instead I got "but like I said, this is your responsibility to know your benefits just like it is outlined in all the forms that you signed". The dentists are the reason this is a 3-star review and not lower, because the clinical care is excellent. But after this experience with the administrative staff, I no longer feel comfortable continuing as a patient here. read more

James R. Mattingly, DDS DABDSM - General Dentistry Near Me - Walnut Creek, California

Best dental office ever! Dr. Mattingly is super easy going and really cares about what is best for you. I went in because my previous dentist shaped my teeth and did a terrible job- made my teeth unsymmetrical o.O - so one can say I was extremely unhappy with my teeth. Dr. Mattingly took a look and gave me a good plan of action to take towards fixing my smile. Maria and Nancy are also totally awesome, as well as Arlene and Erin! Everyone is super friendly and they make going to the dentist a pleasant experience. Thanks all for being you! read more

Dr. Mattingly and his entire staff were extremely knowledgeable and helpful with a long awaited resolution to my sleep apnea. They went above and beyond to assist me with the ProSomnus sleep device which has been integral in getting my overall health back in line. I'm grateful to now feel rested, normalize my blood sugar and give me back my mental clarity. Thanks to Erin for being there to keep the process going to a successful outcome! read more

After 6 years, I'm still happy with the entire staff. I had teeth cleaning today from Aleks and talked to Dr Tan. I realized that I've been lucky to only have 3 dentists since 1977. Two retired and when Dr Mattingly took over the practice, I stayed and continue. On the few occasions I've needed help in a hurry, I've always gotten a fast appointment, which apparently isn't the case with many dentists. I really appreciate it because as much as I hate going to the dentist, I hate pain even more. Without insurance, it's getting pretty expensive but I would never chance one of the cheaper chain offices with dentists that are often mediocre at best, according to what I've read and heard from others. I need the best. read more

Dr. Mattingly is the best!!! The entire team is amazing, and they truly take good care of you. I drive 30+ minutes from the East Bay just to see him, and I have a great experience every time. As someone who is often wary of going to the dentist, Dr. Mattingly makes me feel comfortable and is very straightforward about what he is going to do. He is excellent at what he does, and I trust him completely with my teeth. read more

I can't emphasize how amazing this place is!! The whole staff and Dr Mattingly are nice and honest. If you ask for fees they will let you know up front. I went in thinking I had a broken filling, but it turns out it was a minor chip and hadn't compromised the filling. Dr. Mattingly offered to smooth it out free of charge. I will definitely keep coming here for my other concerns in the near future. Thank you for making a scary experience, such a breeze! read more

James R. Mattingly, DDS DABDSM - Super amazing dental assistant - General Dentistry Near Me - Walnut Creek, California

See all

James and his team are exceptional-- particularly Christallyn Tan, fellow dentist. I hadn't been to the dentist in over two years and she managed me very well with kindness, humor, competency, and had such an easy going fun personality which was perfect for me. I procrastinated on a follow up appointment involving fillings and met with James Mattingly next and he was equally kind with an easy-going attitude. He explained to me the importance of their recommendations. I followed through on my follow up with Christallyn and she was simply AWESOME. Excellent at what she does. Now I won't hesitate to follow through on my routine appointments. Bonus to have their office walking distance from my workplace. I highly recommend their services to anyone looking for a new dentist. Top notch professionals. read more

Very, very, very good dentist. Did I say good? I meant great! Kind and friendly staff, clean office, and the location is great, just off of Ygnacio Valley Road in Walnut Creek, parking is good too. All that is great, but the Dentist, Dr. Mattingly is such a great Dr. He takes time with each patient, asks questions to find out exactly what the problem is, gives his recommendation taking into account everything that is going on. He's my favorite dentist, and I kind of home that you don't choose him because I will have to wait months to see him, but I do want him to grow his business, so I guess I will have to get used to waiting. You will like him as much or more than I do. read more

Just had the best and most gentle cleaning/checkup that I've ever had in my whole life. Don't think I need to say anything else. You rock Jessica. read more

This review is for Dr Mattingly and his partner Dr Tan. These are excellent dentists, who out patient comfort first. I had Dr Tan fill a cavity in my rear molar yesterday, and she was so, so careful, their new equipment made the drilling and filling easy and comfortable. Dr Tan is funny and careful with her work, double checking to make sure it's done right. Her assistant Maria is so careful, lovely to chat with and they work together so nicely as a team. I highly recommend them. PS I am a former patient of Bruce Scott, who owned this practice for many years. The dental assistants are terrific, and when they clean your teeth, they are thorough, but they do not shred your gums. read more

I have been going here for years. Dr. Mattingly is the best! Alyssia is a great hygienist, I only want her to clean my teeth. Arlene is great at the front desk, I look forward to seeing her when I come in. Michelle M. read more

James R. Mattingly, DDS DABDSM - General Dentistry Near Me - Walnut Creek, California

After we bought our house, this office sent a Welcome to the area letter. Extremely pleased with Dr. Mattingly. Highly recommend! The professionalism & quality of work that he and his staff provides is appreciated. read more

James R. Mattingly, DDS DABDSM - Pleasantly pleased with my new crown! Looks so natural. - General Dentistry Near Me - Walnut Creek, California

Best dentist I've ever been to. Brought the entire family over to him and they say the same. Dr. M. is very thorough, clearly explains everything, and is 100% patient focused! Alicia did a great job on the cleaning! Pain free! We'll be back! read more

I highly recommend Dr. Mattingly! I was terrified of going to the dentist. I have had a dentist that was too rough. This was not the case with Dr. Mattingly. He took his time and had a gentle touch. I made an appointment with Dr. Mattingly because I thought I had a cracked tooth. Turns out it was a craze line and not a crack. Dr. Mattingly took his time explaining what a craze line is and what to watch for. Since my exam was a short one he didn't charge me for the exam. I was blown away by his kindness. If you're looking for a new dentist this is definitely the place to come. He is one of the best! read more

I see Dr. Tan at this office. I hadn't been to the dentist in over 2 years due to fear. I've been dealing with the same phobias since I was little. I cannot express enough how great this office has been in accommodating me. They all know how scared I am going in, and I've had nothing but great things to say after walking out. Their dental chair has a massage feature and they even offer lavender scented towels to cover your eyes. It is extremely clean and I feel more comfortable in their office than I have anywhere else. Highly recommend! read more

I have been working with Dr. Mattingly on my Invisalign treatment and he has been a consummate professional the entire time helping ensure that the entire process has been flawless. I had to have some work done (sadly some cavities) and speaking from experience having quite a few as a child I can say this was the BEST experience I have ever had getting cavities fixed. Quick, painless and very complete. I enjoyed that he spoke through the process explaining what he was doing while working and also appreciated that he even let me see some of the work in progress with a mirror. I would highly recommend him to anyone looking for a doctor in the Walnut Creek / Contra Costa area. read more

My husband and I just started going to Dr Mattingly and I was not very pleased. My first appointment wasn't even the cleaning I'd expected, he said he'd "take a look at my teeth and then give me an ESTIMATE" at the end of my visit he seemed rather disappointed that I didn't need any "work" done, just a regular cleaning---which I had to come in for a few days later. My husband went in and his "estimate" was very costly, of course they said everything was absolutely necessary. I don't trust him and we won't be going back. We were really disappointed, he is definitely geared toward cosmetic dentistry and not a good "all around" dentist. read more

Visited Dr. Mattingly a few months back, and I have to agree with Jennifer W. who was not very pleased either. Kevin W. however did bring up some interesting points and has a reasonable surgery/equipment. However I was not offered an iPod to listen to? Overall, I was deeply disappointed with his service and only gave one star for the cleaning service. I have used dentists in other countries as well as the USA, this is my only bad experience. Costs for services was very pricy too, I found to be expensive. The workmanship I was not pleased with either, as a ridge was left on a filling. I would not recommend my friends or family to visit. read more

I agree with Jennifer W. I had a similar experience and I won't be going back either. Im sure he's a great guy and all that but it's not the experience I would expect from a dentist. First thing before even looking at your mouth is a 10 minute video on Invisalign (my teeth aren't visually messed up to start out with that aggressive type of sales pitch) I felt like I was at a used car dealership and kept getting sold on stuff I didn't ask for nor need. It was a quick check up and then boom! What kind of insurance do you have? Ok, it'll cost this much for this or that and I was thinking to myself.. why am I here? I couldn't wait to leave and find a better dentist. I did, so I'm kind of grateful because I would've settled for this place and ended up broke and unsatisfied. I don't like writing bad reviews but I rely on yelp for my choices so i hope it'll help someone out. Ps. After I left i was billed an additional $35.00 dollars for an unknown reason. read more

Dr. Mattingly is wonderful, your comfort and care is his utmost prority. He is on top of his game in terms of the newest care and concerns in dentistry. I have a pre-existing condition that makes my teeth a little more problematic than the average adult, and he helpful ensuring I am taken care of. I love the office staff, the hygenist is awesome and I love our chats about different events that are going on and chocolate. Arlene is wonderful when it comes to taking care of insurance and scheduling. I refer anyone I know that is looking for a dentist here. Dr. Mattingly recently bought I-pods for all the patients to use while in the chair. read more

Dr. Mattingly is an amazing Dentist, He explains everything he does and for people like me who HATE coming to the Dentist he made my trip a easy one. I even got a cavity filled same day I got my cleaning :) He even offered me a IPOD to listen to so I didn't have to hear the drilling of my cavity. This REALLY helped me relax and not be so stressed about coming to the Dentist. Another perk to this office is that their open on Saturdays. The is really helpful for my husband who works 75 miles away. Make sure you double check that you are in Network with this Dentist. read more

I was a patient of Dr. Scott for over 10 years and transitioned to Dr. Mattingly when Dr. Scott retired. I live 70 miles away and there are a lot of choices in my area, but I still go to Dr. Mattingly's office because I like how they manage everything consistently over the years. All the staff members are friendly and genuinely caring. They are super organized and responsible that there are no surprises and disappointments. Dr. Mattingly is a perfectionist and always offers his honest recommendation for his patient's best interest. I've done crowns and Invisalign and I highly recommend Dr. Mattingly. Justine, a hygienist who has been caring for my teeth over 15 years is wonderful and I always enjoy my visit. Arlene and Michelle are so professional and supportive of managing schedules and communication. This awesome team will keep your beautiful smile! read more

Every time I go into their office I am more impressed. I've had bad experiences with dentists as a child and as an adult so I have a lot of anxiety whenever I have an appointment. Dr. Mattingly really goes out of his way to make you feel comfortable, and that extra effort is so appreciated. The hygienists are also very nice - I had a cleaning this morning with Alex and she was great. I highly recommend this office, especially if you have dental anxiety. read more

Dr. Mattingly's office is the best from the front desk (Arlene) the my favorite hygienist (Alicia) and of course D. Mattingly. My family has been going to this office for more years then I can remember and have always had pain free appointments-including my crown work today. I highly recommend him! Sue read more

My husband and I have used Dr. Mattingly as our dentist for the past few years and he and his staff have been great. We had been visiting another dentist in Walnut Creek prior to Dr. Mattingly but didn't feel comfortable with the level of care we received. As another yelper indicates, Dr. Mattingly is on top of his game (diamond certified) and genuinely cares about the patients. His staff (Arlene, Uni, etc.) are also friendly, skilled, and great to work with. We are leaving the Bay Area and relocating to Southern California so we will miss not being able to visit their office. read more

I have always had a great experience at his dentist office. Dr. M is nice, and honest, and direct, doesn't evade the questions and it goes quickly and he spends time to make it right. This is big coming from a dentist hater. Knocking your front teeth out in 1965 in a small town in Nebraska meant going to the only dentist in town that practiced in a basement at the end of a dark hallway. The fat needles and his awful hair and black eyes come roaring back whenever I run across that distinctive dank basement smell. I was under construction with head gears and silver teeth for years after that incident and I remember nothing good. All that bad stuff is nowhere near when I walk into Mattingly's office. If I lived in another state I would probably fly back here to be able to go to him. In fact, I'll probably still have teeth when I am old because of him. Now thats something. read more

My husband and I became regular patients of Dr. Mattingly in 2009 after a coworker highly recommended him. Dr. Mattingly is a great dentist! I couldn't ask for a anyone better (and this comes from a person who absolutely hates dental procedures of ANY kind). Dr. Mattingly is extremely thorough, professional, gentle and caring. He takes his time to explain procedures and continues the explanation while performing the procedures. He cares about the work he performs and wants to know at all times if you are satisfied. The wonderful staff are efficient and quite courteous. The massage chairs and ipods are an added bonus! Regarding the cost: Remember the old adage: "you get what you pay for" ? He isn't the least expensive dentist you will find, but he is not the most expensive, either. For the service you get from Dr. Mattingly, he and his dental practice are worth every penny! read more

Dr. Mattingly is quite possibly the most gentle dentist I have been to. I decided to switch dentists to a local office despite liking my previous dentist. I've had trouble in the past getting and staying numb and having painful injections. Not the case here. I was completely comfortable and liked the sense of security being able to use his drill stop button if I felt any discomfort during the procedure, which I did not need to use. I interacted with two of his assistants, both of which were friendly and professional. It is a relief knowing I have a local office close to where I live that does quality work and truly cares for their patients. read more

This entire office is wonderful. The front desk staff is efficient and helpful. The teeth cleanings are thorough and gentle. Dr.Mattingly is so great- he talks you through the whole process when getting fillings or checking the overall health of your teeth. I've never felt like he was doing anything just to "get money" out of me. The button to stop the drill is a great concept and we had a good chat about the benefits and how it has really eased patients' minds about having to get drilled. Overall, I'm super happy I chose this team for my teeth! read more

If you are afraid of the dentist this is the place to go. They are very kind and do a great job. Also they make you feel comfortable with a massage chair and hot towel while getting a cleaning. read more

My wife and I have been going to Dr. Mattingly for almost 10 years. We moved to Solano County 2 years ago and we still come to Walnut Creek to see him, which says a lot about how happy we are with his office. I hated going to the dentist growing up because it always HURT! They are very gentle but thorough at Dr. Mattingly's. We're always treated very well, the whole staff makes you feel welcome, and Dr. Mattingly tells you the truth and doesn't try to push anything unless he feels you really need it. Thumbs Up all around! read more

I wanted to update my review. I went back to Dr. Mattingly, and he listened and was able to address my concerns. I went to him for a sleep apnea appliance, and I would recommend him if you have sleep apnea. (I did not go to him for general dentistry, so I am unable to recommend since I did not use.) read more

Dr. James Mattingly has been my dentist for nearly 20 years. His skill and his staffs skills are excellent. They are modern, careful and thorough. They walk you through all the procedures before and during the work. Their caring approach has been wonderful for someone that has had a lot of dental issues. read more

The reception staff is always very friendly and welcoming. Justine, a hygenist at the office, has been cleaning my mother's teeth for over thirty years, and has been cleaning my own for the past six. She always does a stellar job with the cleaning, is very personable and has a rad collection of portraits of movie stars and celebrities covering the ceiling of her office so you have something nice to entertain your eyes while she works. Dr. Mattingly is also very nice, and is happy to explain his reasoning during treatment/exam. Highly recommended dental office! read more

I was very happy with the dental care I received from Dr. Mattingly. My first time with him, but he was very professional & skilled. Did a great job with my filling. read more

When we moved to this area I actually used Yelp to help find a good dentist because I've had some bad experiences in the past. I found Dr Mattingly and Dr Tan and am so pleased with them. They always go above and beyond, really taking the time to take great care of you. Exceptional dentists! read more

High tech office! Great experience! Awesome massage comfy chairs! Even got a $160 free toothbrush and tons of other goodies. My teeth didn't hurt like usual, it even has massage chairs! read more

James R. Mattingly, DDS DABDSM - General Dentistry Near Me - Walnut Creek, California

August 17, 2011 James Mattingly, DDS 130 La Casa Via, Suite 202 Walnut Creek, CA 94598 Dear Dr. Mattingly, I wanted to take a moment, on behalf of our entire family, to recognize the exemplary service you and your staff have provided us over the years. Kevin and I have been coming to your office for our dental care for over 32-years! Our children, Ben and Katy, have been your patients since their 'first visit to the dentist' as young children - as many as 22-years ago. Ben and Katy have since flown the nest and continue to be complimented on their beautiful smiles. Ours has been a valued relationship, which is based on complete trust. We have come to know that we can always count on Arlene's accuracy with regards to insurance matters and a courtesy reminder call the day before every appointment. Alicia provides a soft-touch and enlightenment with regards to our ongoing hygiene needs as part of our complete care - thought we'd never say this, but, we actually look forward to getting our teeth cleaned! Thank you, as always, for your expertise and professionalism. You and your entire staff have been a very important and trusted resource for all our family's dental care - including, oversight and guidance during the phase during which our children's teeth were braced in metal We greatly appreciate the easy-to-understand explanations you've provided along the way and your conservative and compassionate approach to dentistry. More personally, we appreciate and thank you for the genuine interest you and your staff have shown toward our family's journey over these many years - we are truly blessed. Sincerely, Kevin & Mary and Ben & Katy Griswold read more

I just got a filling replaced by Dr. Mattingly; apparently my former filling had lost its seal and a new cavity was forming underneath it. And when I say in just had a filling replaced, I mean I literally just got home from his office. This dentist and his staff are wonderful - they are on top it, professional, kind, and make sure to walk you through the entire process. I'm glad I chose Dr. Mattingly as my dentist, and I'm sure you will be, too, whrn you visit them. read more
