Jaclyn Harman

Registered Diagnostic Medical Sonographer

Jaclyn became a Registered Diagnostic Medical Sonographer in 2016. Though she worked in the human medical field for five years, animals remained her true passion.

Jaclyn had previously worked as a Veterinary Assistant for several years while in college and always wished she could combine her career with her love of animals. So, in the spring of 2021, with the help of Dr. Polf, she transitioned to Veterinary Ultrasound.

Outside of work, Jaclyn enjoys riding her childhood pony of 20 years. She lives in Howard County with her husband, son, daughter, and rescue-mutt, Betsy.

Kay Wiles

Katelin Wiles

Registered Diagnostic Medical Sonographer

Katelin attended UMBC Diagnostic Medical Sonography Program in 2020, where she graduated and became registered in both general and obstetric ultrasound. She began her ultrasound journey working in the human field, but after a short time and with the help of Dr. Holly Polf she then began making the transition into the world of veterinary ultrasound. To Katelin this was the best of both worlds.
As a semi new graduate who has always enjoyed working and learning within the medical field and a person that has such love for animals she was now able to take both of those passions and make it into the start of her new career.
In her free time, Katelin enjoys cooking, family time, weekend trips, spending time outdoors, but most of her downtime is spent with her fiance and their four rescue pups Cooper, Baxter, Charlie, and Millie.
