Crystal Marx Nurse Practioner Three Forks Three Rivers Medical Clinic

Crystal Marx


My name is Crystal Marx. I have been a registered nurse since 2001 and a Family Nurse Practitioner since 2019. I obtained a Master's of Science in Nursing from the University of North Dakota.

My family and I live in Three Forks, my husband and two sons; Sawyer and Gabe. Both my husband Mat and I were born and raised in the Gallatin Valley, growing up in Belgrade.

Our family loves baseball, camping, boating, fishing, watching Bobcat football and just being outside in the summer and sometimes in the winter too.

I have worked as a RN in the hospital setting on the medical/surgical unit for 6 years followed by the wound clinic. I continue to be certified in wound care. My family and I feel so grateful to be part of the Three Forks community and I love being able to work so close to home in a great rural clinic.

They currently live here in Three Forks with their daughter, Evelyn, and their two Labradors, Earl and Gunner. They are thrilled to be living back in the Gallatin Valley among her family and all of the recreational opportunities it has to offer – fishing, hunting, skiing, mountain biking, camping, riding horses and hiking are just a few of their favorite things!

Malori is a Three Forks native who returned to Montana after attending College @ Seattle University. She has been the Practice Manager since 2021 but has been with Three Rivers Medical Clinic as a Patient Care Coordinator for 5 years prior to that. Malori discovered her unexpected passion for healthcare when she started caring for patients in her hometown. It is a rewarding honor for her to use her intimate connection with this community to help Three Rivers Clinic.

When she is outside of the clinic, Malori and her 2 boys spend lots of time exploring nature, fishing, catching frogs, snakes and any other creatures they can find.
