Sheep Draw Veterinary Hospital Staff Profiles

Carla Gabel, DVM

Dr. Carla Gabel grew up on a small ranch in Southeastern Colorado. She knew by junior high that she was going to be a veterinarian; living in the country afforded her many learning opportunities in that field.

She attended Colorado State University majoring in Animal Science with an emphasis in Beef Production. She met her husband, Carl Gabel, during undergraduate school. They were wed during Dr. Gabel’s sophomore year of vet school.

Dr. Gabel then went on to graduate from Colorado State University College of Veterinary and Biomedical Sciences in May 1995. Her first job took her to a mixed animal practice in Ft. Scott, Kansas. She found that job to be a wonderful opportunity and gained a wide range of exposure that strengthened her experience and confidence. However, Carla and Carl missed their home state of Colorado so moved back in 1998.

Her second job was at a small animal clinic in a cute little building in Lyons, Colorado. She really enjoyed the relationships she built with the people in that community, but a change in jobs necessitated a move. Dr. Gabel worked at Lyons Animal Clinic until April 2000.

Carl accepted a job in Greeley so their family moved at that time. Dr. Gabel started at Sheep Draw Veterinary Hospital in April 2000. Carl continues as a Loan Officer for a community bank in Greeley. They have three children: a son, and two daughters. Currently they stay very busy with the kids, raising beef cattle and putting up hay.  Dr. Gabel enjoys being a part of the team at Sheep Draw Veterinary Hospital. The professionalism and comradery that is part of the environment make it a wonderful place to work. Dr. Gabel enjoys both the medical and surgical aspects of small animal practice with a special interest in dentistry. Her favorite part of practice is getting to be a part of a family’s relationship from that first puppy or kitten exam to the geriatric exams. Being involved, and a part of all the life stages, and knowing that you are helping a family member is really rewarding. There is nothing like puppy breath!

Lyanne Santistevan, DVM

Lyanne Santistevan grew up north of Holyoke, Colorado on a farm. From barn cats, to guide dogs, horses to cattle, and 4-H hogs, her early years revolved around animals. Originally, she planned to pursue a degree in nursing so that she could make a difference in people’s lives. After volunteering at a local veterinary clinic, however, she realized that she could also help people through veterinary medicine by caring for their animals – a very important part of their lives.

While attending the veterinary school at Colorado State University, Dr. Santistevan was able to pursue many of her passions, including a trip to Honduras for two weeks. While there, her group provided spay and neuter services, rabies vaccines, and classes about livestock production for local farmers. After graduating veterinary school in 2006, Dr. Santistevan practiced at a large, mixed-animal practice in Roseburg, Oregon. Now she, her husband Brian, and children Caleb and Ruby are happy to be at home in Colorado. They love riding their horses, traveling, and spending time with family.

Dr. Santistevan is especially interested in surgery, dentistry, and pain management. Her daily goal is to provide the best possible care to patients while treating each one with kindness and dignity.

Roger Klingenberg, DVM

Dr. Klingenberg was born in Loveland, but raised in Greeley, Colorado, where he attended Greeley Central High School prior to being admitted to Colorado State University. High school was an especially memorable time for him because he met his future wife, Elaine Foe, who currently is a practicing ophthalmologist in Greeley. They have been married since 1978 and have one son, Brad (who is married and living in Chicago), and a daughter, Kate in San Diego.

A merging of animal fascination with a life-long interest in science culminated in Dr. Klingenberg’s graduation from the CSU veterinary program in 1978. He learned the trade in veterinary practices in St. Louis and Houston, while his wife finished medical school and then completed her internship and residency in ophthalmology. They moved back to Greeley in 1985 after an absence of 12 years, and Dr. Foe opened her own eye practice and Dr. Klingenberg founded Sheep Draw Veterinary Hospital. Dr. Klingenberg was the only veterinarian at Sheep Draw for 7 years, but the steady growth of the practice expanded the staff to the current four veterinarians and supporting staff.

Being a pet owner helps Dr. Klingenberg keep in touch with what it is like to be on the other side of the exam table. He has cared for up to four dogs at one time and currently has two. Over the years he has bred and raised litters of Welsh Corgis, Bull Terriers, and Jack Russell Terriers. Unfortunately, his wife and children are very allergic to cats, so he has to enjoy seeing his patient’s cats. In line with his interests in exotic animals, he always maintains a number of snakes, lizards, and turtle/tortoises, as well as the occasional insect. Breeding rare of seldom bred (in captivity) reptiles is a hobby he has never outgrown.

Dr. Klingenberg is a well-known author, speaker, and a researcher of exotic pets, especially on the subject of reptile medicine and surgery. He has authored dozens of papers, articles, text book chapters, and books. His special interests include exotic pet medicine/surgery, orthopedic surgery (especially knees) in dogs and cats, applications of laser surgery, and all preventative health care issues that pertain to his client’s pets.
