Vice President , Cornell O & P

Ken Cornell earned his bachelor degree in biology at St. Anselm’s College in Manchester, NH and completed his postgraduate work in orthotics and prosthetics at UCLA in 1980. Ken has long been active on the board of the New England Chapter of the American Academy of Orthotists and Prosthetists and is a past president. He lectures regularly at local colleges and hospitals. ” I have always considered it an honor to work in the fields of orthotics and prosthetics. I find myself more motivated than ever. Each patient challenges me to apply my experience, knowledge and skill to achieve the highest level of activity possible for that person. For some, that means playing sports, for some it is shopping with family and friends, for others it is being able to walk independently around the house without pain. I have a particular interest in the orthotic management of CMT (Charcot-Marie-Tooth) disease.”

Credo: To take the time to listen and understand, then formulate a plan to make a greater improvement than expected.
