Her experience in Bozeman made her want to return to Montana and practice rural veterinary medicine.

Dr. Peterson is from the small town of Tenino, Washington. She grew up on a small farm which played a large role in her becoming a veterinarian. She has three dogs at home named Greta, Sage, and Josie.

In her free time she enjoys spending time with her husband. She also enjoys running, hiking, fishing, and hunting, especially upland game with her German Shorthaired Pointer, Greta.

Dr. French grew up on a small farm in Minnewaukan, North Dakota with many different animals which fostered her love for animals and veterinary medicine.  She has 2 cats, Gizmo and Bobby; 2 dogs, Ringo and Sandi and a horse, Chester.

When not at the clinic Dr. French can be found cheering on the Reed Point – Rapelje Renegades as her husband coaches football and basketball. When she isn’t at football or basketball games she enjoys spending quality time with her husband and daughter.
