Clinical Expertise

Allen specializes in Cognitive Behavioral Therapy (CBT) for the treatment of depression, alcohol and substance use disorders, social and generalized anxiety, and phobias. He has extensive training with exposure-based therapies for anxiety. Allen also has expertise in treating individuals with a variety of substance use problems and co-occurring mental health concerns. Allen’s therapeutic approach is based on collaboration with the client to develop a personalized plan based on each client’s unique concerns and life circumstances. Personalized plans rely heavily on CBT principles, but also integrate other empirically supported treatments such as Dialectical Behavioral Therapy (DBT) and Acceptance and Commitment Therapy (ACT). Lastly, Allen’s research on substance use problems, personality disorders, and mood/anxiety disorders has been published in numerous peer-reviewed journals and presented at National and International Conferences.

After graduation, he worked as a mental health worker at McLean Hospital in both the dual diagnosis inpatient detoxification unit and the general psychology partial hospitalization program. Allen received his Ph.D. in Clinical Psychology at Indiana University and then completed his predoctoral internship at McLean Hospital/Harvard Medical School.
