Who I work withMy clients are doing some of the most interesting work of their lives.
They are women who live with intention, lead substantive professional and personal lives, and are not satisfied with “fine” being the end of the story. They come to therapy to see what they can’t see: what’s holding them back, what they keep recreating in relationships, what gets in the way of how they actually want to live.
My couples clients bring the same quality of attention. They know something is off, and they are serious enough about the relationship to do something about it.
How I work: A different kind of therapy
My approach is structured, evidence-based, and substantive. We work on what you actually came to work on, and I am honest with you about what I see: where we’re making progress, where we’re circling, and what deserves our attention next. The direction of the work is always yours to shape.
For individual work, I use a depth-oriented approach that draws on feminist frameworks, relational theory, and somatic awareness. We look at patterns: the ones that show up in relationships, in how you work, in how you talk to yourself, and we work to understand where they came from and how to change them. EMDR is one of the tools I use when it fits.
I am EMDR trained (EMDRIA), and it is often where the deepest movement happens: when insight alone hasn’t shifted a pattern, EMDR works with how the original experiences are stored, not just how you think about them.
For couples, I integrate the Gottman Method and Emotionally Focused Therapy (EFT). Gottman gives us tools and language for the patterns. EFT addresses the emotional roots underneath. Together they offer something neither approach does alone.
I hold a PhD in Counselor Education and Supervision and an MBA. The combination shapes how I think about the work — clinically rigorous, and grounded in the realities of how people who lead substantive lives actually move through the world.

Jessie Mastrangelo, PhD, LMHC
I am a licensed mental health counselor with a PhD in Counselor Education and Supervision and an MBA. I work with women and couples in-person at my Arlington, Massachusetts office and via telehealth in Massachusetts and Washington. I supervise pre-licensed clinicians in both states. Mastrangelo Counseling is a growing practice; I am expanding the team in 2026 to serve more clients.
My practice is private pay. I can guide you through the process of submitting to your insurance for reimbursement, but I do not file directly with insurance. The work my clients are doing benefits from being guided by what's actually useful to them rather than what a billing code allows. It also keeps the work fully confidential, which matters.
