He lived and worked as a CPO in Turkey for 10 years. He most recently worked at New England Orthotic and Prosthetic Systems as a manager and practitioner for the past 10 years. During that time he volunteered with Physicians for Peace to help establish a prosthetics center and O&P school at Dicle University in Diyarbakir, Turkey. He also volunteered with LIMBs International and went to Nairobi, Kenya to help train prosthetists who want to use LIMBs Relief 4 bar knee for above knee amputees.

He most recently started full time working with LIMBS International to use the prosthetics center in Diyarbakir, Turkey for many Syrian and Iraqi refugees who experienced limb loss due to the war. A number of Community Based Rehabilitation (CBR) centers are also being planned to help the amputees learn how to use their prosthetic devices properly.
