Meet Our Staff
Dr. Judy Karnia, DVM
I was born and raised on the South Side of Chicago, the youngest of eleven children born to a Polish father and German mother. After my twelve years of Catholic education, I attended Northwestern University where I majored in Classics and was captain of the guard for the Northwestern University Marching Band.
I’ve been a practicing veterinarian since 1994 when I graduated with honors from the University of Illinois College of Veterinary Medicine. As a student at Illinois, I worked extensively with wildlife, holding an assistantship in the college’s Wildlife Ward where I helped rehabilitate injured and ill wildlife such as hawks, kestrels, turtles and raccoons. I also completed an externship at the Cincinnati Zoo, and after graduation, continued to do some veterinary work for the Center for the Reproduction of Endangered Wildlife housed at the Cincinnati Zoo
After graduation, I went into private practice, working at veterinary hospitals in Cincinnati, Oak Park, Illinois and Omaha. For much of this time, I was working as an associate in exclusively feline practices. But in between private practice stints, I also worked as a veterinarian for the Anti-Cruelty Society in Chicago and the Nebraska Humane Society in Omaha.
After bouncing around the Midwest as my husband completed his Ph.D. and worked a few peripatetic jobs, we moved to Scottsdale. We had fallen in love with Arizona on a trip out to Sedona. When the Nebraska winters decimated our roof for the second year in a row, we decided to pursue our infatuation with Arizona. Now, when I’m not working at the clinic, I can be found hiking throughout this beautiful state. I also enjoy running. I’ve completed three marathons, but believe those long distances are a thing of the past. Now it’s mostly 10k’s and smaller races. I read a fair amount of contemporary literature in order to understand what my husband does, and enjoy jazz and other live music. Thursday nights I frequently can be found wandering the Scottsdale Galleries at the ArtWalk.
I’m married to Scott Hermanson, a writer and sometime teacher of English. We have a young daughter, whom you will probably meet at the clinic, and a ball python, whom you may just as well not meet.
My professional life prior to opening the Scottsdale Cat Clinic has given me a wide range of experience in addition to my expertise in feline medicine. I’ve been especially involved in diagnosing and treating geriatric cats. As a practice owner, I’m very committed to keeping myself and my staff updated and educated about the most current state of veterinary medicine. We all look forward to working with you and caring for your cat.
Dr. Dorothy Nelson, DVM
Dr. Dorothy Nelson was born and raised in Orlando, FL and majored in marine biology at Rollins College in Winter Park, FL. She recently graduated from the University of Florida College of Veterinary Medicine (GO GATORS!) and moved to Phoenix in June, 2016 after growing tired of Florida’s humidity and hurricanes.
Dr. Nelson has always had a strong interest in feline medicine and worked for several years at a feline only practice prior to veterinary school. She was vice president of the feline club in veterinary school and did extra course work in the areas of shelter medicine and aquatic animal health. Dr. Nelson also completed an externship at Loggerhead Marine Life Center in Florida working with sea turtles and hopes to someday return to aquatic animal medicine.
When not working at the clinic Dr. Nelson can be found day dreaming about the beach, kayaking (if she can find water), hiking, traveling, or relaxing at home with her 2 cats, dog, and tortoise. She has a soft spot for geriatric cats, and after she lost Rosie, the kitty love of her life, in August to renal failure, she ended up adopting two more geriatric cats from animal control. Dr. Nelson is very passionate about managing chronic kidney disease in older cats and was able to enjoy 5 amazing years with Rosie after her diagnosis. Her hope is to be able help many other cats with kidney disease do the same.
Dr. Kelley DeGroff, DVM
I was born in Torrance, California and spent my childhood years in Scottsdale, Arizona, Kwajalein in the Marshall Islands, and Socorro, New Mexico. I spent my undergraduate years at a small hometown college called New Mexico Tech and earned a bachelors in Biology in 1993. I was honored to receive the Brown Award for outstanding performance in science. I earned money for college by working in a microbiology laboratory studying microbes in soil samples from the surrounding areas.
I attended Colorado State University in Fort Collins where I developed new fun skills such as skiing and backpacking in some of the most beautiful spots in the country. Vet school was a blur of activity which included an externship in Mesa as well as at Harrison Memorial, a low-cost veterinary facility in Denver. My part-time job involved laboratory equipment maintenance for Dr. Ed Hoover, a leader in feline viral research. His lab developed the first successful feline leukemia vaccine. I belonged to the student chapter of AAFP (American Association of Feline Practitioners) and obtained my DVM in 1997.
After graduation, I traveled to Las Vegas, Nevada, where I practiced general small animal medicine and surgery for 20 years. During my Vegas years I had the good fortune of meeting many wonderful people and their animals, as well as further developing my skills in laser surgery and dentistry. My world changed forever with the addition of Joshua, my son, in 2007.
My husband, Michael, and I decided to move back to Scottsdale in search of better schooling for Joshua and to be closer to my family. We are grateful to be back in the Valley of the Sun. We share our lives with two cats. Mac is Mike's cat and you can look but don't touch. Pita is Josh's nighttime cuddle kitty. We are also owned by a paralyzed shih tzu named Brandi. She has a wheelchair, but would rather not be bound to wheels. She prefers sleeping quietly by my side.
In off time I enjoy volunteering to spay and neuter feral cats, hiking, yoga and scuba diving. I am thrilled to be joining the wonderful team at Scottsdale Cat Clinic. I look forward to meeting you and your furry felines so that we may work together to make their lives healthier.

He plays soccer, reads a tremendous amount of contemporary literature, and tries to play the guitar.
