Dr. Rob Clark DVM, CCRT

Practice Limited to Orthopedic Surgery

Dr. Clark currently only practices orthopedic consultations, and surgery. He performs a large number of orthopedic surgeries including cruciate ligament surgeries (extra capsular/lateral fabellar suture, tightrope, and TPLO / CBLO techniques), angular limb correction surgery and corrective osteotomies, fracture repair, arthrodesis, hip surgery, medially luxating patella surgery, and stifle arthroscopy.

In his spare time, he spends a lot of time at the gym – and you’d recognize him – at 6’6″ he’s hard to miss!
