Eric S. Eisenberg, M.S. CPO

  • Licensed Prosthetist / Orthotist
  • Owner of BioTech Limb and Brace, LLC
  • Certified in Prosthetics and Orthotics
  • Prosthetic education from Florida International University
  • Orthotic education from Northwestern University

Eric was raised in a home that exposed him to two very different sides of prosthetics and orthotics:  patient and physician.  His father is an orthopedic surgeon and civilian volunteer who established the first amputee skiing program for returning Vietnam veterans at Fitzsimmon Army Hospital in Denver, Colorado.  His younger sister is affected by cerebral palsy.  "As a child I saw the positive impact the field of orthotics has had on my sister's life," Eric explains.  "Orthoses allowed her to walk, prevented contractures, and helped to support and align her spine and extremities."


Hans Harshberger, CPO

  • Licensed Prosthetist / Orthotist
  • Received Bachelor's Degree in Health Sciences with Prosthetics and Orthotics option from California State University in Dominguez Hills.
  • Has been working in the field for 20 years.

"I'm a third-generation prosthetist.  My grandfather lost his leg in a car accident, and that experience motivated him to open his own prosthetics facility in Toledo, Ohio.  My father grew up in his father's business, then decided to open a facility of his own in Birmingham, Alabama.  I started working in the family business when I was 15 years old, and I knew then that I wanted to follow in my grandfather's and my father's footsteps, helping amputees regain their independence." - Hans Harshberger
