When Therapy Hasn’t Worked There’s a Different Way Forward
Dr. Larry Shapiro, PhD, is a licensed clinical psychologist with more than 30 years of
experience helping adults overcome anxiety, depression, trauma, relationship problems, and
other emotional challenges. He is the owner of Quantum Behavioral, LLC, a telehealth-only
private practice providing online therapy to adults in Missouri, New Jersey, and more than
40 states through PSYPACT.
Dr. Shapiro specializes in treatment-resistant and complex cases that have not responded
to previous therapy, medication, or conventional mental health treatment, including
medication-resistant depression and anxiety. He holds a PhD in Clinical Psychology and
serves as adjunct faculty at Washington University School of Medicine in St. Louis.
His approach is direct, active, and structured, focused on helping patients identify and
eliminate the patterns that keep them stuck rather than managing symptoms indefinitely.
Quantum Behavioral is designed for adults who are ready to do the work necessary to
create meaningful and lasting change.
All therapy sessions are conducted through secure, HIPAA-compliant telehealth, allowing
adults to access expert psychological care from the privacy and convenience of their home,
office, or other confidential location.

Client Feedback
"Dr. Shapiro has been awesome since the first time I had an appointment. His demeanor makes it very easy to talk about things that are normally difficult to discuss. His approach to my issues has been greatly beneficial. I have returned to him recently with an issue and he is guiding me through the healing process. Very highly recommend Dr. Shapiro. Second to none."
"Dr. Shapiro saved my life, and my marriage. I was at rock bottom when I walked into his office. I am now 7 years clean, still happily married, and raising my 3 kiddos! As a Marine I thought I could handle any problem... I was wrong. If he can help me get to where I am, please trust that he can help you. Thanks again Doc!"
“Dr. Shapiro was remarkably effective in guiding me out of the darkest period in my life. I’d been successfully treated for depression with traditional medications for most of my adult life (over 20 years) but became Treatment Resistant. My psychiatrist prescribed ketamine treatment which pulled me away from the edge thankfully, but in the aftermath, I needed more to help me fully engage in life, joy, all of my emotions. I’ve been to many therapists over the years, so I found Dr. Shapiro (Larry) very refreshing in his directness, decisiveness, and deeply felt expressions of empathy. He had particular understanding of my challenges dealing with autoimmune disease and chronic pain. Despite being separated by a screen, I felt that Larry truly saw me, understood me…and I trusted him as he challenged me. I only needed his help for a short period, considering everything that we dealt with in that time. It was incredibly efficient. And I continue to work on the things in my life that he helpfully and assertively underlined for me. Thank you Larry.”
