EBOS Where Have You Been ALL My Maxillary and Mandibular Life!!!!
Thank you Dr. G and team for the MOST amazing kind gracious pain-free experience I’ve ever had in my dental care history! Dr. G your level of acumen expertise and humaneness is extraordinary and invaluable, thank you for being the person and the professional you are. You have put together a team of equal outstanding quality proficiency and grace. I am so very, very fortunate to have found your practice through Delta Dental. What is a blessed grateful mystery is that from the moment I was awakened from the surgery to the next morning, over 24 hours passed and I am still trying to comprehend how you managed to pull 2 completely broken-off teeth to their root and I have yet to feel any discomfort, swollen jaw or remote pain. Dr. G you are an incredible brilliant surgeon with an equally superb team!!!!!

Very professional - A Great Dental Experience
The staff was very professional and friendly. The offices are nice and easy to get to. Dr. McCormick was very attentive to my needs. This is my family’s new “go to” dentist! Overall one of my best dental visits ever. I highly recommend Dr. McCormick! I left my dentist of five years for Dr. McCormick and I am glad that I did.

Wisdom Teeth Extraction
I just had a wisdom teeth extraction at East Bay Oral Surgery. The staff was very sweet. I was anxious for the procedure but the staff was very reassuring. It was quick and easy, I was sent home with lots of things to aid in the pain. The instructions were very helpful. I had very little swelling and less than 24 hours later was feeling almost 100%! I will definitely go back for any other procedures.

Simply the best
Who wants to have dental oral surgery? One of the most anxiety filled activities we ever go through. But if you do Dr. Grombach and staff are the tops in the field, from diagnosis to appointment, to prep to the surgery and of course the after care! Thanks again to the entire office!
