The Anxiety & Panic Treatment Center, LLC is a Portland, Oregon cognitive and behavioral psychology practice dedicated entirely to the treatment of anxiety disorders in adults. Founded by Robert W. McLellarn, Ph.D., the practice reflects more than four decades of clinical experience: Dr. McLellarn earned his B.A. in English Literature from Oregon State University, his M.Ed. in Counseling from Lewis and Clark College in Portland, and his Master's and Ph.D. in Clinical Psychology from the University of Montana. He completed his internship at the Los Angeles County/University of Southern California Medical Center and a two-year residency/fellowship at Oregon Health & Science University, and has been a licensed psychologist in Oregon (license #634) since 1985. He is BTTI-trained through the International OCD Foundation (IOCDF) and serves on the BTTI training faculty, and has completed specialized training in trichotillomania and skin picking through the Trichotillomania Learning Center. For more than ten years he ran weekly treatment groups for OCD, Panic Disorder, Social Anxiety, and Generalized Anxiety Disorder. Today the center serves clients throughout Oregon (and beyond) via secure telehealth, focusing on the full spectrum of anxiety and OCD-spectrum conditions including trichotillomania, dermatillomania, and Body Dysmorphic Disorder. A unique touch: Georgie, a 60-lb Yellow Lab / Golden Retriever mix and Program Assistance Dog from Dogs for Better Lives in Central Point, OR, joined the clinic in August 2018 as a 'co-therapist.' The practice also offers a self-published e-book, 'How to Find a Therapist to Treat Your Anxiety Disorder,' drawing on Dr. McLellarn's 40 years of clinical wisdom to help prospective clients choose the right specialist.
