Dr Koos and his staff are kind, and professional , providing the best oral surgical care available. The facility is warm and inviting, helping the patient feel at ease in an understandably anxious situation. I have referred many friends and acquaintances to Dr Koos, and Dr Krajl, and will continue to do so.

The treatment I received was beyond great. I pride my self in noticing talent and vision in people and I say with complete confidence that the staff at ORA is the power house of service and professionalism. I had 2 morals removed within minutes with excellent care and follow up. No pain, no issues, just complete satisfaction.

Before this, I was completely terrified of going to the dentist (and I am 24yrs old) but now I cannot wait to go back and make ORA my number 1 dentistry for all my needs.

Sr Koos and his staff were simply amazing in giving me an appointment and surgery within a few days. He has a state of the art facility and well trained staff. The parking is adjacent to the surgery center and very accessible. I recommend Dr Koos for everyone.

Dr. Koos and his team were really nice and explained everything thoroughly. I don't remember anything in the office after the sedation but the practice is beautiful and the staff is so great. They don't talk down to me because I'm a teenager and they took great care of me.

Dr. Koos and staff are professional. Procedure went well. The only suggestion I have to have available service recommendations for support as needed to cope with oral surgery as it it is very emotional experience which varies among patients.
