Miko Flasik, DVM

Veterinarian

Dr. Flasik earned her DVM from Colorado State University in 2018. In her youth, she volunteered and worked for a local animal shelter. In college, she explored her passion for diversity and social justice. Now, as a veterinarian, Dr. Flasik connects with people and empowers them to make the best decisions for their furry friends. She loves helping people understand the complexities of their pets’ health concerns and providing them with the options and resources they need.

One of her most important pieces of advice for pet parents is to brush their pet’s teeth as often as possible. Dr. Flasik recommends finding a toothpaste flavor your pet likes and slowly helping them get used to having their mouth handled and their teeth and gums touched. It can take time, but the results are more than worth it! Good periodontal health is essential to good overall health. Another thing she wants pet parents to know is that pictures and videos of their pets are super helpful to their treatment. If your pet is limping, coughing, or just acting differently, a video can help Dr. Flasik get a better idea of what is going on.

At home, Dr. Flasik has a handsome black senior cat named Malcolm, who is in hospice care due to heart failure. Originally given a 6-month prognosis, Malcolm is still kicking after 3 years, and he regularly greets Dr. Flasik at the door when she returns home from work. Outside the practice, Dr. Flasik is a huge foodie who loves trying new restaurants, along with cooking and baking. She also enjoys singing karaoke and napping. But in addition to relaxing outside of work, Dr. Flasik also makes time to help others, having volunteered as a victim advocate at rape crisis centers in Colorado and Philadelphia for a combined 10 years.
