Our Doctors


Dr. David Kovalik:

Dr. Kovalik's love of animals began with his collies growing up. While he grew up with dogs, most people remark about his affection for cats! He hasn't met a cat he didn't like.

Initially, Dr. Kovalik pursued his passion for reading in school and received a BA in English and MA in Eastern Classics. In addition, he traveled abroad and taught English in China and Thailand for several years. Dr. Kovalik eventually reconnected with his love of animals and returned to the U.S. to attend veterinary school at The Ohio State University. Since graduating, Dr. Kovalik attended an internship in Rochester, New York, practiced emergency medicine in Bangor, Maine, and practiced general medicine in Philadelphia, Washington, DC, and northern Virginia.

Throughout his career, Dr. Kovalik's commitment to service has led him to routinely volunteer for the Humane Society, World Vets, and GeoVets. Dr. Kovalik is a member of the American Veterinary Medical Association, the Arizona Veterinary Medical Veterinary Association, the American Association of Feline Practitioners, and he serves as a board member of GeoVets. 

When he's not working, Dr. Kovalik loves to read, study history, and spend time with his family - his wife Barb, and his two rescue pets - a fluffy food-obsessed cat named Charlie, and an exceptionally-enthusiastic miniature dachshund named Marley.  

 Dr. Nicholas Volkman:  

Dr. Volkman is an excellent veterinarian with more than 28 years experience practicing emergency and general medicine. Dr. Volkman graduated with honors from veterinary school at the University of Pennsylvania in 1989 and practiced medicine for several years in New Jersey and Pennsylvania. Dr. Volkman moved to Arizona in 2009 and has worked in several clinics in Northern Arizona since then.      


Dr. Volkman's wealth of experience combined with his ongoing education make him well-informed and suited to provide the same progressive care for your pet that Dr. Kovalik provides. Dr. Volkman typically works at the clinic one day a week to give Dr. Kovalik a much needed day off!  


Dr. Chelsey Calhoun:

Dr. Calhoun (née Brown) is a beloved veterinarian who has worked at Sedona Animal Clinic for nearly half her life! She worked as a technician for many years, and after earning a veterinary degree from Colorado State University, Dr. Calhoun returned to work at the clinic as a veterinarian.  


Dr. Calhoun had twin girls in 2017 and now spends most of her time being a super mom. She can be found working at Sedona Animal Clinic on special occasions, when she has a free minute!
