Dr. Marc and his team are simply the best! I have been a client for many years, and he has done everything from simple cleanings to veneers for me. His work is excellent and his entire staff is welcoming and courteous. Whatever concerns or apprehension you may have about your dental work, Dr. Marc and everyone at Geissberger DDS will put you at ease. 10/10

It seems universal that going to the dentist is something we all wish we didn't have to do. It's not fun. And yet, it's so important and our teeth and gum health is a super important part of our overall health. And, in my opinion, our smile matters too!

After going to several dentists that were just meh, we were referred to Dr. Marc. We pay a little more, but it's worth every dollar. His office staff and dental hygienists are great, the office is calm and pleasant, and my overall experience is better than with any dentist I've been too.

Their equipment seems state of the art and everyone seems to keep up to date on the best techniques and updated procedures to make the experience the best it can be.

I've had to have a lot of work done on my teeth and Dr. Marc is always supportive, caring, and efficient - never takes more time than necessary but also has enough time to chat and make sure I'm comfortable.

He's also honest and conservative in his recommendations, while including me in a discussion about the best course of action and allowing plenty of space for me to ask questions and even challenge him.

One of the best experiences was getting veneers on my 2 front teeth. They look AMAZING! Dr. Marc really cares about the problem, the process, and the results. He's got a great attention to detail, he's scientifically/mechanically skillful, and he's also an artist with his craft being the maintenance and creation of beautiful teeth and smiles.

I'm so glad that I switched to Dr. Marc many years ago...and I know you will be too!

Dr Marc is really the best of the best. In 2013 I sought his advise as a second opinion. He was the most patient, measured, and honest dentists I had ever encountered. He helped me understand that it was too soon to know if an implant was needed; my second root canal had not fully healed. I liked him so much I joined as a regular patient. He helped me heal that problem tooth and keep it as long as possible since it was a prominent upper. The time did come for it to be removed nine years later, at which point he guided me through the implant process with care. My implant looks great. The surgeon he referred, Dr. Mynsberge, was also wonderful.

Dr. Geissberger was highly recommended to me by another dental practitioner out of my area. I felt instantly comfortable and at ease with Dr. Marc and his friendly staff. I was in need of a new crown and some bonding, and Dr. Marc listened to me, answered all of my questions (very patiently) and even texted me back after hours. I am so ecstatic about my new smile! I absolutely love it. It is above and beyond what I expected, and I owe it all to Dr. Marc. Dr. Marc was extremely professional, personable and really is an artist. He was extremely meticulous about every detail and very deliberate in his intent to satisfy his patient. He did! I would highly recommend Dr. Marc. You will not be disappointed. Thank you to Dr. Marc and his wonderful staff!

Short version - Dr. Marc Geissberger is an outstanding dentist (no matter how complex the problem) and everyone is his office is a top notch professional. I highly recommend him and his staff for both routine work (cleaning, etc) and any level of required dental surgery. The front end process (scheduling) is also extremely well managed by two highly competent and kind individuals. If you want more details, see below.

Long version - My father was a dentist (and you likely understand what that means when it comes to evaluating dentists) and I had the same dentist (who was fantastic) for the last 10 years. We recently moved to Mill Valley, CA and I had to find a new dentist (right in the middle of Covid and half way through a dental implant process). Luckily, Dr Marc was recommended to me. After years of needing very little dental work, I have had a bad streak lately (replaced cap, fix old filling, implant for tooth that had to be pulled last year). So, I have had the chance to experience Dr. Marc's skills quite a bit. He is technically highly competent and has great "chair side" manner. He also has an excellent network. The person he referred me to for part of the implant process (putting in the implant itself) was also outstanding.

I go for cleanings quarterly and have experienced a couple of different hygienists. They also have the highest level of skill, quality, and empathy. I have a bad gag reflex and they take such great care to minimize any issues with that.

The front office staff are kind and very efficient and very good at helping find a schedule that works. I love that the office opens at 7am. If I have to go to the dentist, I want to get it over with first thing in the morning. The office is easy to find and parking is free and plentiful.

Can’t say enough about how happy I am to have been referred to Doctor Geissberger after my dentist retired. What a fabulous dentist, a beautiful office, and great assistants. I’m a fearful patient and they made me feel completely at ease. I’m actually looking forward to my next visit. And by the way, I’m the daughter of a dentist so I feel able to recognize the best!

Dr. Geissberger is so professional and he takes great care in his work. The work he did on my front tooth was amazing and ultimately resulted in me pleading with him to creat my new smile! His is a clearly passionate about making a difference in his Patients and he and his staff have allowed me to smile again with confidence. Thank you Dr G!

An amazing and professional team!!
Got four crowns done here and I'm amazed by the results. They matched them perfectly with my canines. His office did everything they could to make me feel comfortable. His office is tasteful, artistic and modern. Personally, I felt that at every part of the procedure he was concerned on how I was doing. He made sure I was comfortable at all times. Continually asking "doin' ok Jess", and if I didn't answer he would make sure to ask again a little later just in case. Definitely much more of a caring attitude than I have had at many other dental offices.
Besides his bedside manner you could tell his dental team trusts him and works hard for him as well. Everyone from his front desk to his assistants are happy to have you there and it's very easy to feel welcome the entire time you're there.
An amazing dental experience.
