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.

The people at the front desk are lovely. Very helpful. But the student I had was so incredibly slow. She didn't know who to blow dry my hair. After 40 minutes and only one portion of my hair done, I asked her get someone to help her. So for a base color and blow dry, I was there from 5:45 until almost 8:30. The only saving grace is that it doesn't happen that often.
