I have been an amputee for 8 years.  As an amputee it is important to keep on top of changes all the time and see my prosthetist anytime I have a problem.  Recently I was diagnosed with bursitis and couldn’t wear my prosthesis.  I had to get around in a wheelchair.

I called M. H. Mandelbaum O&P.  They gave me an appointment right away and, within a few hours, they fabricated a diagnostic leg and got me walking comfortably.  I wheeled into their office in a wheelchair and walked out.  Their office will do anything for you – they always fit you in.  From the staff on the phone to the Prosthetist, they always take that extra time.
