Professional Statement

I am a licensed clinical psychologist practicing in Waltham, MA. My therapeutic approach is rooted in an existential, humanistic perspective and draws from psychodynamic and relational theories.

I received my bachelor's degree in psychology from the University of Rochester and my doctoral degree in clinical psychology (PsyD) from William James College. I completed a clinical practicum at the Massachusetts Mental Health Center (BIDMC/Harvard Medical School), an APA approved internship at the Brigham and Women's Faulkner Hospital (Harvard teaching hospital) and Rhode Island College Counseling Center. I completed my postdoctoral fellowship at the Brandeis University Counseling Center.

My experience is broad. I have mostly worked with college students and adults on life transitions, existential questions and challenges, identity development, anxiety, depression, grief/loss, trauma and relationship problems. I have 5 years of supervised training doing psychological and psychoeducational assessments for children, college students and adults, and have experience working with people struggling with serious mental illnesses and their families. I have also lectured at Boston University, Brandeis University, William James College and Temple University on topics such as: psychodynamic psychotherapy, adult psychopathology, suicide and suicide prevention, and schizophrenia and other psychotic disorders.

Outside of work, I value spending quality time with family and friends. I also enjoy seeing live music (well, I used to!), binging Netflix, and watching/playing sports.

Testimonials

"Dr. Kaplan supported tremendously when it came to exploring the different aspects of my life and where there was room for improvement. He challenged me in a way that led to true self-improvement and stronger interpersonal relationships. He is incredibly sympathetic, genuine and patient; I truly felt as though he was present and listened without judgement during all of our sessions"

“Aaron is just the best. He will try his hardest to make you feel better about yourself. He’s very cool and easy to vent to. I will miss you!!”

“Dr. Kaplan was someone I felt I could trust and respect in a time when I was generally unsure of either. He is adaptable, bold, and assuring. I appreciate his sensitive, welcoming, and unassuming demeanor and felt that the work we did together was truly collaborative. He gave me the tools and confidence to help myself outside of our sessions.”

“For the short time I saw Aaron, I began to see myself as a stronger and more independent person, even in my moments of weakness. The reason I think so highly of Aaron is that he had a natural ability to locate me in my present moment; he never guided our sessions with a particular agenda, and had a keen sense of my own willingness to share and be open. With that in mind, he attuned his practice to challenge and nurture my own self-development. The culture Aaron creates in a therapy session is intentional from the beginning. Because of this, he was someone who I turned to in both times of crisis and also in moments of serenity where I was able to bask in my own self-discovery. Working with Aaron was an extremely important part of my year in graduate school. I had a very trusting relationship with Aaron, one that I valued immensely as it helped me enter a new chapter of my life.”
