Had a new patient exam and cleaning today done by Dr. Gruhler… I have to start off by saying WOW. The office is sleek and clean, and all the staff were friendly and smiling. The best thing was the scan they took of my teeth! Dr. Gruhler was able to blow up my smile on the screen in a 3D image and show me the different angles and aspects of my smile to help me understand his recommendations. Dr. Gruhler and Rosa are very kind, attentive, and patient. I cannot thank Marin Modern Dentistry enough for the great experience today, and am thankful to call them my new dental home!
