“I got into the field by way of a volley ball accident in high school; afterwards I had been fit with a custom knee orthosis.  When I was going to college for computer science I would stop by the shop to see how the prosthetics were made.  I was told since I was so interested I should apply to New York University, which I did.  Most of my computer science credits did not apply to the P&O field so I was literally the last graduate from the NYU program, after completing summer school.  I have been with MHMO&P since 1991.”
Areas of interest: Lower Limb Amputees, TBI Patients, Pediatrics to Geriatric Orthotics.
I am currently on staff @ most hospitals in Suffolk County and go to many Skilled Nursing Facilities in Nassau and Suffolk Counties on a weekly basis.
