Meet our Team

Caleb Engel grew up in Omaha, Nebraska. He is a Cornhusker, having attended the University of Nebraska to study biology. Dr. Engel then attended Iowa State University’s veterinary school, graduating in 2019. He moved to Denver in the fall of that year, joining the team at Mile High Animal Hospital. He has two orange tabby cats, Miso and Mochi, that he shares with his partner, who is also a veterinarian. In his free time, he enjoys skiing, hiking, and biking. He has an affection for all animals, but especially for dogs, cats, and alpacas.

Dr. Timmerman has lived most of her life in Colorado but cannot claim native status as she was born in St. Louis, Missouri. Following the advice of a mentor to achieve her goal of becoming a veterinarian, she returned to Missouri to attend the University of Missouri-Columbia, where she received both her undergraduate and veterinary degrees. After graduation, the mountains and dry air of Colorado called her back, and she has practiced in various parts of the Denver metro area since her return. She was part of the team at Mile High Animal Hospital from the fall of 2016 to the summer of 2019 and rejoined us in December of 2020.

She has a furry crew of three at home: Dynia- a spunky cattle dog mix that knows no strangers; Zucca- a quirky cattle dog mix that has more of a “neurotic” personality; and Chewy (pictured)- a lovable old-man rescue who came in severely obese and achieved his weight loss goals with Dr. Timmerman’s guidance. In her free time, Dr. Timmerman enjoys taking walks and hikes with the dogs, relaxing on her patio, and enjoying time with friends. The best part of veterinary medicine for Dr. Timmerman is the relationships she develops with clients and their pets over the weeks, months, and years of working together!

Dr. Braun grew up without any pets but always knew that animals were meant to be a part of her life. She volunteered at veterinary hospitals and animal sanctuaries and decided early on that veterinary medicine was her calling. She attended the University of Dayton, where she obtained a degree in biology, and then graduated from The Ohio State University College of Veterinary Medicine before moving to Denver. She currently has 3 pets--two rescue greyhounds named Kallie and Emmie, and an orange tabby cat named Bingley. Her professional interests include surgery, cardiology, and anything greyhound related! In her free time, she enjoys outdoor rock climbing, skiing, and hiking.

Olivia is a proud Colorado native who graduated from the Community College of Denver's Veterinary Technician program in May 2019. She originally thought she wanted to be a veterinarian but realized she would get more one-on-one time with pets as a technician. She is passionate about keeping animals happy and healthy, both mentally and physically. In her spare time, she loves hiking and going to dog parks with her Chihuahua/Jack Russel Terrier sidekick, Grants, playing games with family and friends, camping, dirt biking in the mountains, and attending concerts.

Jennie has always loved animals, as far back as she can remember.  Growing up she was always drawn to animals and knew one day her career would center around them.  Her original dream was to be a veterinarian but learned she is far happier as an animal nurse.  She was graduated from Bel-Rea Institute in 2006 and is known as the cat whisperer.  Part of a large family Jennie always had one or more pets in the house.  She grew up in gymnastics and Girl Scouts, earning the Gold Award with a project involving horses.  She did English horseback riding in middle and high school and currently Irish dances whenever she can.  Jennie’s pets include an adopted blind boy cat named Aran and a polydactyl American Curl named Catailia.  She also lives with the feisty calico Tumbleweed, sweet tortoiseshell Sagebrush and her mother’s medical alert Chihuahua Mapleleaf.  In her free time, she can often be found writing, swimming, or curled up with a good book, cup of tea, and a cat or two snuggled close.

Hannah moved to Colorado from Richmond, Virginia four years ago to be close to the mountains while pursuing education to become a veterinary technician. Since she was little, Hannah has loved animals of all kinds and at age 7 she decided she was going to have a career working with them. She could not be happier with her decision! Hannah graduated from Bel-Rea Institute of Animal Technology in December 2020 and joined the team at Mile High Animal Hospital. In her free time, Hannah enjoys hiking, making art and music, cooking, and spending time with her pets. She has a very handsome cat named Momo and an adorable bearded dragon named Arwen. Her favorite thing about working at Mile High Animal Hospital is the amazing team we have here!

Stacey grew up in Colorado before moving to a university in Tennesse where she majored in English and religion. Not long after graduation, however, she decided to return to school to pursue work with her first love: animals! Stacey graduated from Pima Medical Institute's Veterinary Technician program and became a Certified Veterinary Technician. Stacey has a passion for canine behavior, which is inspired by her own canine companions, Calvin, and Ryder. In her free time, Stacey likes to cuddle with her dogs while making jewelry to raise money for homeless pets. She is happy to be working at Mile High Animal Hospital, where the entire team values every animal’s physical and mental wellbeing.
