Dr. Allison Jenkins wasn’t born in Colorado, but she got here as fast as she could. She graduated with Honors from Texas A & M University in 1999, then immediately moved west to the mountains. Allison worked as a veterinary technician in Crested Butte before starting veterinary school at Colorado State University. During vet school, Allison was chosen to participate in a wildlife research program in South Africa, under the direction of world-renowned wildlife vet, Dr. Cobus Raath. Over a two-year period, she also conducted equine toxicology research on Easter Island. Dr. Jenkins received her veterinary degree from CSU in 2004. She then spent the first two years as an equine vet in Oregon and Texas before finding her true calling in small animal veterinary medicine.
Dr. Allison Jenkins moved back to Colorado in 2010, where and when she met her husband, Ashton. They spent their newlywed year restoring the 1890 Victorian at 3727 W. 32nd Ave. to create a space where pets could feel safe and cared for. In 2013, Highlands Animal Clinic was born. Dr. Allison and Ashton (and their 2 dogs, Cash and Greta) lived upstairs for 2 years after the clinic opened and loved becoming a part of the neighborhood.
Allison and Ashton are the grateful parents of two amazing human children, River and Beau. They are also the guardians of a rescue Pyrenees mix, Stevie; the clinic kitty, Jemmy; Allison’s horse, Casey and an English Lab, Jerry.
Dr. Allison Jenkins is a resident and cheerleader for the Highlands neighborhood. She feels lucky to have found her place in this community and looks forward to serving you and your pets.

Testimonials
What the PET PARENTS are saying
"Good clinic- they are always helpful. My dog actually likes going to the vet, and I am glad we are customers here. I recommend their services to anyone in the area. The very professional and informative staff are always willing to answer any questions you have. Also, it's a nice location in the middle of a quaint town across from a coffee shop. I know it's a good place because my dog entered alone (due to covid-19) and came out tail wagging and smiling!!”
- Janelle W.
"We love Highlands Animal Clinic. Dr. Anderson has taken incredible care of our dog Lucy for the past two years and his care has been the best. Lucy is our baby and means the world to us, and they are the only veterinary office we trust with her. Dr. Anderson is so gentle with Lucy, and really listens to my husband or myself when we have questions or concerns. I truly get the feeling that everyone cares so much for her when we are there. Thank you so much for the incredible care you provide our girl.”
- Samantha A.
"I absolutely LOVE everyone who works here. They have taken amazing care of both our huskies every time, always taking as much time as needed with their appointments (and it’s always affordable). Dr. Jenkins saved our little foster puppy’s life by diagnosing early stages of parvo while she was doing our dogs’ annual wellness exam - our foster pup didn’t even have an appointment, and we wouldn’t have known anything was wrong until it was too late if she hadn’t been so on top of it and cared so much. It’s a huge relief to have such an amazing veterinary team nearby."
- Maddie M
"This team of veterinarians is amazing. Our kitty was just diagnosed with diabetes, and they’ve been so helpful and patient in getting her back to health. Our doggo loves them, too! I think we’ve seen all the doctors and each one of them has gone above and beyond to provide us with information during COVID and answer any and all questions we may have.”
- Kate W.
"I have been going to Highlands Animal Clinic since they opened. I have to give my praises to Dr. Jenkins. When I first met her (Dr. Jenkins), I had an 8-year-old Bull-mastiff/Lab mix that had mobility issues. My dog could not get up on the couch or climb in bed and going for a walk was painful. Allison did 6 acupuncture treatments on my old dog. This old dog is now almost 16. She can still get on the couch and climb in bed. Nowadays we go in for routine laser therapy and I see a quality of life in my dog who has surpassed her years and is still thriving. I am not sure who is more determined - My 16-year-old big dog or the Veterinarian?! I think it is a team effort! I love it and appreciate the folks at Highlands Animal Clinic. As an owner of 4 senior pets - I highly recommend this clinic.”
