Identical twin brothers Keith and Ken Cornell founded Cornell Orthotics & Prosthetics in 1985. Sharing an uncommon dedication for excellence in their field, the brothers have steadily developed Cornell Orthotics & Prosthetics into a multi-site, patient-care practice in the greater Boston area. The two certified prosthetists and orthotists, along with the rest of our staff, are dedicated to providing exceptional care for whoever walks through our doors.

Ken Cornell, CO, FAAOP
Vice President

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.

Nicole “Nicky” Yeh, MS, CPO

Prosthetist/Orthotist

Nicole has been ABC Certified CPO since 2012 and she loves her job. Her education includes a B.S. in Biological Anthropology from Duke University, M.S. in Biomedical Engineering from University of California in Davis, and post-grad certificates in Orthotics and Prosthetics from Northwestern University. She specializes in pediatrics, especially regarding children with neuromuscular involvement, but looks forward to working with more adults. She is experienced with custom lower and upper extremity orthoses as well as bracing for idiopathic and neuromuscular scoliosis, and has been trained in Elaine Owens’ paradigm of AFO alignment.

Her philosophy is “treat every patient as I want my own child or family member treated. Every device should be the same quality that I demand for my own family”. Nicole also believes that she and the patient are a team. She works hard to listen to the patient’s words. If he or she can’t speak, then facial expressions and movements, if that is his/her means of communication. She works with the patient to set goals for the device and then works hard to design and fit a device to reach those goals. She tells “her” kids (and now her adult friends, too!) that their braces should help them “run faster and jump higher.”
