I come to this office in pain, not able to take care of my daughter the way I wanted or play with her. Working was impossible. They have improved my life so very much. They always treat me with respect and explain my care wonderfully!

Best Visit Ever!

Feb 15, 2014 by Charnell G.

I had been seeing another doctor for about a year and no treatment or options were given. First appt with Dr. Sharon Ross was wonderful due to a physical of my problem (never done at other doctor) and options for correction right away! I will always come back!

I highly recommend OSI. The whole staff are very firendly. All lobby's, waiting rooms, and treatment rooms are very clean. Doctors take their time to explain and care about you. Sometimes Doctors take longer to see you but it's all well worth it.

Best Doctors in the Area!

I have never met a doctor like Dr. Cyr. He is truly a doctor that take time with his patients and goes into detail of what needs to get done! But before you see him I had the ultimate pleasure of dealing with his P.A. Sharon Ross she is also great and both with a heart of gold!

Dr. Fieldland and his staff have been exceptional. I've been suffering since 2009 and after a long search and many doctors I'm finally on the mend. I used to take so many pain medicines but after my procedures I'm down to 1. The staff here really cares and always are professional no matter how many times I call.
