Absolutely the best dental and hygienist practice. Always feel like I am the #1 client when I visit. Felt super safe, clean and professional. Highly recommend them all the time.

I fly and drive considerable distances to see Dr. Koeltl...I trust him, he does superior work and I have every intention of staying with him as a patient. The dental hygienist I saw today was outstanding and I will ask specifically for her next time!

I have never understood dental care until I spoke to about my care with the Doc. His office, equipment and video capabilities were important for my dental education. I also learned about my bite guard and sleep problems. I needed a cleaning and found that was just the tip of the iceberg. I was very impressed and glad My daughter referred me. He is a definite find.

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.
