I appreciate the professionalism and concern for the overall health of the patients at this office. I am especially thankful for the time Dr. Koeltl takes to explain dental procedures and why they are necessary. I never fully understood how dental health can and will affect your overall health until I came to Dr. Koeltl and the Diablo Dental Group.

Dr. Hong and his assistants provide professional, caring service and are most pleasant even though going to the dentist is not fun. He's been my dentist for many years, and I trust him to fix my teeth.

If you are looking for a dentist practice that is professional, kind, and great at helping with any dental issues you may have-this is the place for you. They take meticulous care to make sure issues don’t escalate. I am in great hands with all the staff- the reception, the staff that works with insurance, the wonderful hygienists and technicians and especially the dentists.

After searching many years for a dentist who listened to patients, was a considerate health care provider, and provided quality dentistry, I came upon Dr. Valerie Johnston. She is the best! Precise in her work and wonderfully friendly. I love her. I also appreciate Jan, her steadfast assistant, who always has an interesting story or two to share.

I have been a client/friend of the staff at Diablo Dental for over 25 years. They have always been honest, fair, transparent and helpful. I feel they are concerned about my comfort during any appointment and procedure. When I go to their office it is with confidence that they have my best interests in mind.
