Just finished therapy on Dec. 17th 2021. Dr. Mantas is the best, hands down! I had a damaged femoral nerve from surgery and could not walk. I began my therapy with a leg brace and a walker. After six months I walked out of the office without a cane, and I am walking better every week, just as Dr. Mantas said I would. The therapy was intense for months, but so worth it. He really cares about everyone he is helping and you will get his personalized attention. His helper Patti is the best also. I really miss them and am so grateful to Dr.Mantas for his help and excellent care! Laraine Phillips

In a matter of a few short weeks, I went from limping and in pain to gaining near full range of motion and relief from pain thanks to Mantas! In many places, you never know which therapist you'll be assigned at each visit. At One on One, PT is truly one on one! The facility is bright and clean, the atmosphere so friendly and the services are personalized to match patient need. I am most grateful for being able to get back to normal mobility thanks to Mantas!

I have gone to Mantas for 2 rotor cuff surgeries, and now a torn hip labrum surgery. First I don't mind going there, its like a family. Such comfortable surroundings. Joanne the receptionist is totally friendly, knowledgeable, and caring. No question is stupid, and Mantas will let you know in detail what is being done. If you listen to him, do your homework, you will get better! He is also willing to help you meet healthy goals in your lifestyle. Mantas and Joanna are not just my PT people, I consider them friends!
