Meet the Team

Shelby Arrieta, DVM

Shelby was born and raised in Colorado and grew up riding and showing horses in the hunter/jumper circuit. She completed her undergraduate degree in biology at Regis University in Denver, CO before receiving her veterinary degree from Colorado State University in 2017.

After graduation, she completed a year-long intensive internship at a large referral hospital in California called Steinbeck Country Equine Clinic. After California, she returned to Colorado to work with Dr. Lee Mueller and purchased his practice in 2021 when he decided to step back his work-load.

When not working, Shelby enjoys being outdoors and going on adventures with her husband Aaron and their three dogs Ollie, Millie, and Ernie.

Tom Traxler – Office Manager

Many of you might not know that Tom is Dr. Arrieta’s dad. Tom spent his life working in the construction industry. He focused on estimating large projects and work acquisitions for a large mechanical contractor in Denver before going off on his own as a private consultant for many contractors around Colorado.

He supported and encouraged her love of horses and spent the weekends feeding her horses treats and driving her all over for competitions.

After 42 years in the construction industry, he retired and is now managing office operations for Ponderosa Equine. In his free time, he enjoys golfing and spending time with his wife Dena and their two chocolate labs Trixie and Nala.

Jacklyn White – Veterinary Assistant

Although Jackie was born in Michigan, she moved to Parker, CO when she was 8 years old and considers the Rocky Mountain State her home. She rode her first horse when she was just over 1 year old on her Grandpa’s fruit farm in Northern Michigan and was immediately bitten by the horse-loving bug.

She started out showing Morgans and Saddlebreds when she was 5 years old and continued throughout her youth before discovering her love for Quarter Horses and barrel racing. While she absolutely loves all animals, she is especially proud to be the mom of her 5 precious fur babies.

She has three horses named Treble, Lucy, and Linus and two dogs named Ranger and Marsha.
