Dr. Oster did a great job removing my cataracts. I had RK in the 80's so it was a difficult surgery and I had no issues. Which I could have had several problems because of it. He is a very skilled eye surgeon who cares about his patients. I would recommend him to anyone. The before care and after care I received form him and his staff, Tami and Alea was great. They make sure you understand the instructions and check on you, I can not say enough about the great experience I had. Thank you.

I can't speak to Dr. Oster's competence, but based on his long list of accomplishments, he is likely an excellent physician. However, I won't hire a physician that does not talk to his/her patients. Apparently Dr. Oster leaves that up to his assistants, as I found out when I asked a simple question and he quickly exited the exam room. The abruptness was rather strange. I want a physician that will communicate with me directly and in a courteous, professional manner.
Very friendly and patient.

DO NOT GO TO THIS PHYSICIAN. He lies to his patients and instructs the staff to do the same. Tammy is the most rude medical office person I have ever experienced. I am in the health business and if any of my staff treated a patient like she treated me I would fire them. Tammy lied to me about why my moms surgery was rescheduled. She blamed in on the surgery center even though it was the physician that wanted to change the date so he could recover from a 100 mile race. IT WAS THE LYING......

I regret having my surgery done by Dr. Oster. His office staff in Grand Junction is incompetent. I read the negative reviews and did not heed their advice. My mistake. The negative reviews were accurate.
