Board-certified veterinary surgeons
Only veterinarians who have successfully completed the rigorous certification requirements of the American College of Veterinary Surgeons (ACVS) receive the prestigious Diplomate designation.

Kristin Kirkby Shaw, DVM, MS, PhD
Diplomate ACVS, Diplomate ACVSMR
Dr. Kristin Kirkby Shaw is a small animal surgeon and rehabilitation specialist whose career has focused on bridging the gap between these two disciplines. She received her DVM from the University of Florida in 2003, followed by a rotating internship in Colorado, and small animal surgery residency at the University of Florida. Dr. Kirkby Shaw completed both her MS and PhD at the University of Florida.
As a surgical resident, Dr. Kirkby Shaw recognized the need for rehabilitation for her patients and took graduate courses in rehabilitation science, exercise science and therapeutic modalities. In 2008 she became a Certified Canine Rehabilitation Therapist (CCRT). In 2009 she became board certified in veterinary surgery (DACVS-SA). Following her residency, she remained at UF as faculty in surgery and founded the University of Florida Small Animal Rehabilitation and Fitness Center. In 2010 she was awarded the Outstanding Young Alumni Award by the University of Florida. In 2013, she became a Diplomate of the American College of Veterinary Sports Medicine and Rehabilitation (DACVSMR).
Dr. Kirkby Shaw has been a surgeon and rehabilitation specialist in Seattle since 2010. She sees appointments both at Animal Surgical and through our rehab department, SOUND Vet Rehab. She specializes in seeing dogs with hip dysplasia, elbow dysplasia, cranial cruciate ligament rupture, and arthritis. Her goal is to provide a comprehensive plan that is customized to each patient. While surgery is often part of the treatment plan, she can also discuss and provide non-surgical options such as intra-articular therapy (PRP, stem cell therapy), pain management, nutritional guidance and rehabilitation therapy. Dr. Kirkby Shaw is also a consultant with the Woodland Park Zoo, where she provides specific guidance on rehabilitation and pain management techniques for zoo animals with arthritis.
Dr. Kirkby Shaw is past-president of the American Association of Rehabilitation Veterinarians and is currently an instructor for the Canine Rehabilitation Institute. In 2018 she was the recipient of the John J. Sherman Award for Excellence in Veterinary Rehabilitation. She is a frequent invited speaker at national and international veterinary conferences and has authored numerous journal articles and text book chapters related to veterinary surgery and rehabilitation.
She doesn’t leave the world of rehab behind when she goes home. Her husband, Aaron, is an occupational therapist/certified hand therapist and owner of MoveMend, physical and occupational therapy practices in the Seattle area. Kristin and Aaron are proud parents of Beans (Frenchie) and Arrow (Labrador). In Kristin’s rare spare time she enjoys running, snowboarding, hiking, yoga, and travel.
