You will work closely with the core MFT faculty as you pursue your degree. The MFT faculty will teach the majority of your courses, provide the majority of your clinical supervision, and one of the MFT faculty members will serve as the chair of your graduate committee.

The three core MFT faculty all hold doctoral degrees in Marriage and Family Therapy from COAMFTE accredited programs and are Licensed Marriage and Family Therapists (LMFTs) and AAMFT Clinical Fellows and Approved Supervisors. Faculty are actively involved in their professions through membership in organizations including the Oklahoma Association for Marriage and Family Therapy, the American Association for Marriage and Family Therapy, and the National Council on Family Relations. Faculty regularly present at state, national, and international conferences and publish their work in peer-reviewed academic journals.

“I'm very thankful for my time in OSU's MFT program. The faculty were so helpful to me when I was figuring out the right post-graduation path for me and which doctorate program was the best fit for my career goals. I was well prepared to step into a doctoral program after consistently being exposed to research throughout the program and working closely with my thesis advisor and committee. I highly recommend this program to students who are looking to get quality training in both clinical work and research!”

“MFT faculty’s care and respect for one another, their students, the program, and the profession became very clear within the first day of being introduced. My experiences throughout the program continued to show this unwavering dedication. Their ongoing support and encouragement for growth lay a strong foundation for continued learning and development as a young therapist even after graduation.”
