Enjoyed my first visit with Julie the hygienist. There was an opening available the next day to start my treatment and I am very impressed with Dr. Martin and the whole staff.

My family of 4 have been patients of Dr. Greg for nearly 20 years. Our experiences have been always positive. The entire staff is one of the friendliest, helpful and knowledgeable. Dr. Greg has helped us maintain the good health of our teeth and doesn't over prescribe procedures-only what is necessary. I highly recommend Dr. Greg Martin and his staff.

Dr. Martin and his amazing staff are world-class and top-tier. I've been a patient of Dr. Martin for the last year and a half, moving here from the east coast and getting all new doctors can be overwhelming. I have received nothing but kindness, laughs, and professionalism since seeing them; highly recommended.

Just had my first couple of appointments, including a crown. The staff is wonderful. They went the extra mile to accommodate my schedule and pain level. The office is immaculately clean and Dr. Martin is very skilled and caring. I can't think of a single thing that could be improved. As close to perfection as a dental office can get.

After not being to the dentist for a. we will just say a while. I was anxious about my visit. The staff was so welcoming, nonjudgmental, professional, and I really felt they truly love the profession they work in and the patients they serve! I highly recommend Dr. Martin and his team!
