Kecia Valdez, DVM

Kecia is the founder and owner of Jules, Lathrop, and Arroyo Veterinary Centers. She was born in New Mexico and moved to Colorado to attend Colorado State University Veterinary School. Her original dreams consisted of becoming a human doctor, but her newly acquired schnauzer puppy (named Jules) quickly changed her mind. After becoming a concerned pet owner, she knew that becoming a veterinarian was her true calling.

Kecia graduated with honors and was inducted into Phi Zeta, a veterinary honor society in 1998. Her medical interests include dentistry, soft tissue surgery, helping control the pet population, and schnauzers. When she is not busy with her patient’s medical cases, Kecia enjoys spending time with her three children Isabella, Francisco, and Sergio. She also finds herself lost in a good book regularly and taking as many pictures as she can.
