He then went on to study veterinary medicine at Kansas State University, earning his Doctorate of Veterinary Medicine in 2007. Dr. Bessmer moved to Hartley, Iowa, where he practiced for one year before moving back to Sioux City. He joined the team at Roach Animal Hospital, where he practiced for nearly four years. In 2012 Aaron and his wife Rachel purchased Elk Creek Animal Hospital. Then in 2020, the Bessmer’s purchased Vermillion Veterinary Clinic. Dr. Bessmer and Rachel split their time between the two clinics and enjoy working with all their clients in the tri-state area. Dr. Bessmer and his wife Rachel have three girls, two dogs, and four barn cats that keep them busy in their spare time. Dr. Bessmer also enjoys being outdoors, hunting, fishing, and watching the Huskers play football.
Dr. Kalene Gross

Office Manager & Practice Owner
Rachel was born and raised in Nebraska. Her passion for animals began at an early age when she would accompany her Dad while calling on farmers. She graduated from Wayne State College with a degree in business management. After Dr. Bessmer and Rachel married, they purchased Vermillion Veterinary Clinic with the goal of providing the best customer service and patient care to their clients and creating the best possible workplace environment for their employees. The duo works well together with their two degrees, and although Dr. Bessmer’s main focus is the animals and Rachel’s main focus is the business side, running a vet clinic is a family affair, and they both work in all parts of the clinic. You will often find their daughters helping as well.
Lydia has been working at Elk Creek Animal Hospital and Vermillion Veterinary Clinic since March 2019. She was born in Spearfish, South Dakota, and raised in Storm Lake, Iowa. She graduated from Western Iowa Tech Community College with an Associate of Arts degree and an Associate of Science degree. She hopes to continue her education in the veterinary field and would one day love to have a little farm where she could have many kinds of animals. When she is not at work, Lydia likes to spend time with her two dogs, whom she loves to spoil and treat like her kids.
Clay was born and raised in Homer, NE. After graduating high school, he went to college at Wayne State University, where he received a Bachelor’s Degree in exercise science. A dedicated athlete his whole life, Clay set three different track and field records during his time at Wayne State, a fitting achievement considering his fitness passion.
Since a young age, Clay has also had a passion for animals, which eventually led him to work for us here at Elk Creek Animal Hospital starting in 2019. Clay has been an indispensable part of the Elk Creek family since the day he started. He is always there to anchor the rest of us and keep us motivated. If there is a stressful situation or a difficult case, Clay can maintain a positive attitude, and that positive attitude is always infectious.
Clay and his girlfriend, Melissa, have a rambunctious Alaskan Malamute named Layla that keeps them busy and entertained. When he’s not playing fetch with Layla, Clay likes to play the guitar, exercise, and spend time with his friends and family.
