From birth to old age, find your family doctor at Mesa Primary Care

By Kristy Bleizeffer Jun 23, 2016

Providing excellent health care means bringing services to our patients, close to where you live. That’s why we built Mesa Primary Care in West Casper, the fastest-growing residential area in the city. We offer patient-centered care backed by Wyoming Medical Center’s full network of medical specialists.

After lifestyle changes – exercising regularly, eating nutritious foods and not smoking – choosing the right primary care provider is one of the most important decisions you can make for managing your health. Primary care providers work with patients over a lifetime and are the first stop to more specialized care. 

Mesa Primary Care offers extended hours, same-day appointments and an on-call provider available 24/7 to fit your family’s lifestyle.


Dr. Dunn is board certified in family medicine. He is the medical director at Mesa where he also sees patients. “This sounds corny, but I love the Norman Rockwell approach to medicine. There is a Rockwell painting where the doctor is listening to a young child’s doll with his stethoscope. That has always kind of stuck with me,” he said. “I feel very fortunate to be in that kind of setting and to be involved in people’s lives.” Read about his red-nose approach to medicine.


Dr. Talbot is board certified in family medicine. She grew up in the Big Horn Basin and graduated high school in Worland. She attended the University of Wyoming for her undergraduate degree and became interested in medicine while watching her brother struggle through several health problems. She wanted to help other patients going through similar journeys.  “I’m a local girl practicing medicine in my home state,” she said. “I love the people and the down-to-earth attitude that dominates here.” Read her suggestions for becoming an empowered patient.


Dr. Knudson specializes in internal medicine and pediatrics. She was born and raised in North Dakota and earned her medical degree from St. Matthew’s University School of Medicine in the Cayman Islands. “I think there is a shift in hospitals across the United States in that we want to keep people out of the hospital if we can. We want to keep them healthy,” she said. “The best way to do that is to have good primary care so people see their provider on a regular basis.” Read more about her here.


Dr. Rosalez is board certified in family medicine. She completed her residency at the University of Wyoming Family Medicine program in Casper. She earned her Doctor of Osteopathic Medicine at Des Moines University. “To be in family medicine, you have to love your community. You are your patients’ doctor, but you’re also their support system,” she said. “I like when I run into one of my patients in the grocery story, because it makes Casper feel like a small community and that I was able to help someone.” Read about Osteopathic Manipulative Treatment can help relieve pain.
