Dr. Happawana earned his Bachelor of Science degree in psychology from the University of California San Diego in La Jolla, California in 2015. He went on to obtain a master’s degree (2017) and doctorate (2020) in clinical, counseling, and applied psychology from William Paterson University in Wayne, New Jersey. He has also earned a post-doctoral Master of Science degree in clinical psychopharmacology (2025) from Drake University in Des Moines, Iowa. This degree partially fulfills the requirements to prescribe medication as a psychologist.

Dr. Happawana has over 10 years of direct forensic and clinical experience. Training sites included a variety of locations, some of which included the Kessler Institute for Rehabilitation, Weill-Cornell Medical Center, and the New York University Langone Comprehensive Epilepsy Center. He was a direct commission into the United States Air Force in 2019 and completed his internship/residency with the 88th medical group at Wright-Patterson Air Force Base. He then completed his permanent duty assignment at Joint Base Elmendorf-Richardson with the 673d Operational Medical Readiness Squadron.

He has since transitioned into full-time private practice to focus solely on forensic and clinical psychology. He is a diplomate of the American Board of Professional Psychology, Fellow with the American Academy of Clinical Psychology, and currently serves as a chair/board examiner for candidates who are seeking board certification in clinical psychology.
