About
Megan D. Colletta, LCSW
I am an integrative psychotherapist with twenty years of practice across the United States and the United Kingdom. My work is grounded in evidence-based practice and shaped by the conviction that good therapy is both rigorous and human — solution-focused, non-judgemental, and compassionate.
How I work
I match the approach to the person, not the person to the approach
My approach is integrative, drawing primarily on cognitive behavioural therapy, mindfulness-based cognitive therapy, EMDR, Acceptance and Commitment Therapy, and Prolonged Grief Disorder Therapy. I match the approach to the person and the moment, rather than asking the person to fit the approach.
Sessions are solution-focused and integrative. We will work together to define what you want to be different, name what is getting in the way, and build a practice — both in and outside of session — that moves you toward it.

Research and academic work
Research-informed therapy
Alongside private practice, I am a Senior Clinical Research Therapist at the University of Exeter Mood Disorders Centre, where I deliver and study evidence-based treatments for depression and prolonged grief.
I am a co-author on the 2025 Cambridge University Press paper An evaluation of a pilot high-intensity treatment pathway for prolonged grief reactions in a Devon NHS Talking Therapies service (Goff, Carson, Ladwa, Colletta, Topcu, Shear & Dunn, The Cognitive Behaviour Therapist), and acknowledged in the ADepT trial (Dunn et al., 2023, eClinicalMedicine) — one of the most-cited recent UK depression-therapy trials.
I was featured on the Oxford Mindfulness Podcast with Professor Barney Dunn, discussing positive emotion and mindfulness in Letting the Light In (watch on YouTube).

Education
Outside of work
What keeps me grounded
When I'm not in session, you'll find me on the water on my paddleboard, working on a creative project or unrolling my yoga mat. These practices keep me grounded, curious and present — the same qualities I bring to the therapy room. I believe that tending to creativity, movement and presence is part of a balanced, whole life, both for me and those I work with.
