My name is Michael Devine and I am a Licensed Professional Counselor Supervisor in the state of Texas and I own a private Plano counseling and coaching practice.I am originally from Columbus, Ohio where I was born and raised. I received my Bachelor’s Degree in Psychology from Otterbein College: A small private school in the suburbs of Columbus. After braving the winters of the Midwest, I decided it was time to move to warmer and greener pastures of Dallas, Texas.   I received my Master’s Degree in Psychology from the University of North Texas where I gained specialized training in Marriage & Family Counseling, Individual Psychodynamic/Cognitive Behavioral Counseling, College Counseling, and Psychological Assessment.

I spent the majority of my clinical training and internship working in many different settings to gather additional training to become the best possible therapist that I could be for my clients. Some of the settings that I have worked in are listed below:

  • UNT Counseling & Testing Center
  • UNT Psychology Clinic
  • DFW Center for Autism
  • Nelson Residential Treatment Center for Children
  • Hickory Trail Mental Hospital
  • Adapt Mobile Crisis Assessment
  • The Irving Family Advocacy Center

I am an active member in the American Counseling Association, Texas Counseling Association, and the Texas Association of Marriage and Family Counselors. My practice is part of a cutting edge group practice that believes strongly in the mind/body connection and treats the individual client as a whole; providing its clients with full service psychological, spiritual, nutritional, and psychiatric needs.
