Zach Shepherd

Psychiatric Mental Health Nurse Practitioner 

Zach offers a balanced, holistic approach to mental health due to his experience as a Registered Nurse and in the adolescent treatment setting. Though his experience provides expertise across the broad spectrum of mental health, he specializes in medication management, anxiety care, mood disorders, and treatment for adolescents, young adults, and adults.


Zach earned his Associates's degree and Bachelors's of Nursing through Dixie State University and attended Vanderbilt University where he earned a Master's of Science in Nursing as a Psychiatric Mental Health Nurse Practitioner (Lifespan Focused).  A perennial student, he endeavors to grow his knowledge base by searching out new and alternative treatments and researching approved and evidence-based treatment plans. He believes in centering his care and research on the needs of each patient rather than employing a one-size-fits-all approach.


Zach is interested in how mental health impacts every person in one way or another throughout their life cycle. Though mental health manifests and impacts people in different ways, we are all constantly changing and adapting along with our mental health. He is captivated by the ability that all people have to make positive change and finds lasting satisfaction in helping others discover a new course in life.

I've always had a desire to help others; exploring this passion led me to healthcare. Seeing patients progress on their journey to wellness inspires me.  When I'm not in the office, you can always find me curled up on the couch reading a book or planning a vacation for a new adventure.
