Dr. Casna is a New Hampshire native. An inherent curiosity of the natural world and passion for helping others led him to pursue a career in veterinary medicine. Dr. Casna worked as a veterinary technician while attending Keene State College in Keene, NH where he earned his bachelor’s degree in biology. Upon completion of his undergraduate degree he moved to Blacksburg, VA to attend veterinary school at Virginia Tech.
Throughout veterinary school Dr. Casna explored many facets of veterinary medicine, including research, food animal medicine, and zoo medicine. He was accepted into a prestigious summer research program at Stanford University’s School of Medicine, where he conducted research in novel treatments for human stroke patients using animal models. He presented his research at the Merial National Veterinary Scholars Symposium at UC Davis. Dr. Casna was also awarded a coveted clinical extern position at the San Diego Zoo, where he assisted board-certified small animal surgeons on multiple surgeries including an ovariohysterectomy in a Snow Leopard and a mass removal from a Tasmanian Devil. It was during this experience he learned that his more broad passion for surgery could mix some with his love of zoo medicine and he decided to pursue a career as a small animal surgeon.
After graduating veterinary school in 2017, Dr. Casna completed a one year small animal surgery and medicine rotating internship at Carolina Veterinary Specialists in Winston Salem, NC. Dr. Casna joined CVSS in 2018 for a one year surgical internship and remains a member of the CVSS team as a surgical resident. Dr. Casna and his wife (also a veterinarian) enjoy backpacking and hiking with their four dogs, two great danes, a pit bull, and a maltese. He is also an avid fly fisherman and DIY home project enthusiast.
