Dr. Jensen Stulp purchased what is now Lamar Animal Medical Center in 2015. The location had significant sentimental value as Dr. Stulp remembered running “the loop” from pharmacy to exam room to lobby as a boy while his father, Dr. John Stulp practiced veterinary medicine alongside the clinic’s owner, Dr. Sniff. This veterinary location dates back to 1947 and has a long history of serving both large and small veterinary needs in Southeastern Colorado. Dr. Jensen and Annessa Stulp are thankful to have the opportunity to give this historical location a renewed life, and continue to provide for the needs of animals in rural Colorado.

Dr. Alisha Mason
ASSOCIATE VETERINARIAN
Alisha Mason, DVM, graduated from Washington State University in 2022. Dr. Mason is a Colorado native and was born and raised in the Pueblo area, but spent most of her childhood running up and down the Arkansas River Valley visiting family and riding alongside her dad helping him fix farming equipment. She grew up in 4H showing dogs, cattle, market goats and sheep, and had a variety of pets through the years. Before veterinary school she worked for other mixed animal practices in Southeastern Colorado fueling her drive to return to the area and mixed animal work which is where she found her home at LAMC. Dr. Mason also serves on the Colorado Veterinary Medical Association as a regional leader. In her day to day work, she enjoys herd work and complex internal medicine cases the most, but she loves coming to work every day because it means helping you and your animals.
When not at work, you can often find her out at North Gateway Park on her stand up paddle board with one of her 3 dogs Lilly, Nova, and Pip. If she’s not there, she’s likely spending time with her husband Liam, volunteering, traveling, or gathering with close friends and family enjoying card and board games.
