Bethany Bratlay

Bethany has been passionately working in the animal medical field for over 10 years. Born and raised in Chicago, she moved to New Mexico in Feb 2020 with her husband and their many pets. While in Chicago she worked 6 years as a vet technician doing physical and laser therapy. Working for Chamisa has been an amazing experience and has also given her the opportunity to get back into doing physical and laser therapy. She's earned her certification in laser therapy and is continuing education on the subject. Bethany and her husband love to foster pets, especially helping those with medical needs, and they hope to one day start a pet rescue of their own.

Melissa Dezendorf, DVM

A Florida native, Dr. Melissa grew up on the Gulf Coast before moving to Louisiana in 2005. Once in Louisiana, she met her husband and attended veterinary school at Louisiana State University. They moved to New Mexico in 2019 to escape the mosquitoes, hurricanes and humidity.


Dr. Melissa lives in Los Alamos with her husband, their son, three rescued dogs and a cat. She enjoys hiking, a variety of artistic hobbies, and horseback riding.

Dr. Sabina Johnson has been practicing veterinary medicine and surgery in Los Alamos for the last 23 years. She has worked as a full time veterinarian doing surgery, dental procedures, diagnosing internal medicine, infectious disease and other cases. She is especially interested in internal and geriatric medicine. Joining Chamisa has opened up an exciting new direction to undertake that supports these interests. She is very thankful for all the wonderful clients and pets throughout the years and for all their support.

She has 3 adult children, a supportive husband, 3 cats and 4 chickens. On her days off she enjoys mountain bike riding, hiking, skiing and watching the wildlife that show up in the backyard.

The Chamisa Care Team

Fiona Jolly

Niko started off as a kennel technician in a clinic boarding facility after having worked many service jobs over the years. He quickly decided that whatever job he worked from that point on would be with animals, if he could manage it. With the loss of that job due to covid and resorting to a pizza delivery job (again), he was grateful to have the connection to get back into the field and work as a vet assistant for Chamisa at the start of 2021. He loves meeting all the pets on the job and admires the neat houses he gets to visit in Santa Fe and the area. He lives in Los Alamos with his wife Lilly and their cat Cato.

My name is Amanda Mouradian and I graduated from Kansas State University College of Veterinary Medicine in 2001. I have been practicing veterinary medicine for 20 years, with 4 years as a full time care provider in a critical care hospital, 4 years as a clinic manager and 7 more years providing sickness and wellness care for dogs and cats. After all of these years in a clinic setting, I have taken the leap to provide exceptionally personalized care for your furry family members in your own home.

Fiona, our wonderful Office Manager, was born and raised in New Mexico. She previously lived in South America for 3 years. Fiona is passionately active in the western horsemanship world and is fluent in Spanish. Fiona has one adult daughter and two dogs. In her spare time she enjoys hiking and horseback riding.
