Serena Moore
ADMINISTRATIVE DIRECTOR
I earned my Bachelor’s Degree in Psychology with a minor in Business from the University of Nebraska–Lincoln, and I’ve been passionate about this work ever since. I have over seven years of experience supporting and coordinating mental health services, particularly for court-involved individuals.
In my role, I oversee the day-to-day operations of our administrative office, manage billing and credentialing, and help ensure that our team runs smoothly and efficiently. I enjoy being the go-to person for problem-solving and finding creative, practical solutions to everyday challenges.
Outside of work, you’ll usually find me in the kitchen experimenting with new recipes, digging in the garden, or road-tripping to explore national parks.

Thomas McPherson
OPERATIONS DIRECTOR
Hi, my name’s Thomas McPherson (he/him) and I manage the practice’s public relations and marketing activities. I also try to keep computers running, the plumbing unclogged, and the light bulbs glowing.
I graduated from Metropolitan State College (now Metropolitan State University) in Denver, Colorado with a B.A. in English with minors in History and Journalism. I moved to Nebraska in 2010, and obtained a certification in Technical Writing, also from Metro State. When I’m not at work or tending to fatherly duties I busy myself with gardening or yard work. I really enjoy art and graphic design, and if something’s geeky chances are I’m a fan.

In both my teaching and my role at NMHC, I value the opportunity to build connections and support the people around me.
