"Had an overall great experience with Dr. Ryan. The staff was very courteous and professional. Most important, the work they did, (two implants, to hold lower dentures) was very secure and I'm free of the hassle and pain. I was concerned at first but he answered all my questions and the whole procedure went well. I definitely would recomend them if you need that type of work done. 2 thumbs up!"
~ Keith I.
"Best doc we have ever been to. My son felt safe and relaxed with him and his staff."
~ George G.

"The office is well run. Everyone I had contact with was friendly and knowledgeable. Procedures were explained and all questions answered. Oral surgery can be an intimidating proposition, but Dr. Ryan and his staff are sensitive to that by providing excellent pain management and results."
