Dr. Evan Dowdy

doctor dowdy

Growing up on his grandfather’s cattle ranch in Wyoming, Evan Dowdy learned common sense and the basics of animal medicine. After earning his DVM from Colorado State University School of Veterinary Medicine, he returned to work on the ranch, where he was the only veterinarian within 40 miles. Devoting his career as a full-time veterinarian, he gathered even more experience as a full-time generalist and part-time emergency vet for three years in Pennsylvania.

In 1991, Dr. Dowdy joined Dr. Kiefer at Kiefer Veterinary Clinic, now Horizon Veterinary Clinic, a respected animal hospital established in 1946, where he continues a tradition of superior care for pets. Dr. Dowdy is currently the owner of Horizon Veterinary Clinic, and Dr. Kiefer has retired. Small animal surgery, internal medicine, acupuncture, and treatment of chronic ear problems are a few of his areas of interest. He is a member of American Veterinary Medical Association, American Animal Hospital Association (AAHA), Denver Area Veterinary Medical Society, Colorado Veterinary Medical Association, and Who’s Who in Veterinary Medicine (1991-1992).

“As long as I can remember, I wanted to work with animals. Treating animals is a great privilege and a responsibility I take very seriously. That’s why I make sure all my four-legged patients enjoy gentle care and advanced treatments.”

Dr. Martha Levin


Dr. Martha Levin grew up in Lancaster, Pennsylvania and moved to Colorado to pursue her education in Veterinary Medicine (and satisfy her love of the mountains!). She earned a Master’s degree in Biomedical Sciences and a Doctorate of Veterinary Medicine, both from Colorado State University. While in school, Dr. Levin gained experience with pets, horses, and livestock, and even dabbled in a little laboratory research. Ultimately, she found her calling in general practice and joined the Horizon team in 2015.

Dr. Levin enjoys internal medicine and surgery. She has volunteered at a Native American spay/neuter clinic and hopes to someday combine her veterinary skills with missionary work in developing countries. She loves to spend time with friends and family, and enjoys hiking, skiing, and snowshoeing. Dr. Levin is active in her church as a Sunday School teacher and musician (she plays the violin).

“Ever since childhood I wanted to work with animals, but I never seriously considered veterinary medicine until I was a senior in college. Apparently my family knew all along I should be a veterinarian, but it took me awhile to realize it! I can’t think of anything more fulfilling that I would rather do. ”

Horizon Pets

Maui Boo

IMG_20171111_120032738_HDRMaui Boo came to Horizon in the fall of 2010. Injured and found by the side of the road, she quickly worked her way into our hearts. She mostly hides in the back, but occasionally makes an appearance if needing a treat.








IMG_20160418_150443943Newton is our newest official greeter! Bred by one of our receptionists, Maurya, he wormed his way into Dr. Evan Dowdy’s heart and found a permanent home with us here at Horizon. He loves his job saying hello to everyone as they come and go, but once 5pm comes his internal clock says “Let’s go!” He is also a world-renowned escape artist and keeps us all on our toes.









In Loving Memory

david the cat

David came to Horizon Veterinary Clinic as an eight-week-old kitten in 2002. He had an injured tail that failed to heal and ultimately had to be partially amputated. However, he hasn’t let his ‘disability’ slow him down! He enjoys munching on Greenies, greeting clients, loving Maui Boo, and getting into mischief around the clinic.
