Marissa Adams, IEDS

Recovery Coach & Patient Advocate

Marissa Adams, Eating Disorder Recovery Coach at Side Quest Psychotherapy serving clients nationwide
Marissa Adams, IEDS

Hi! I’m a neurodivergent Recovery Coach, recovered from my own eating disorder—so I know firsthand that healing is messy, nonlinear, and totally worth it.

I came to this work because I couldn’t find support that held all of me at once — the eating disorder, the neurodivergence, my intersex traits, the years of being labeled “too complex” and “treatment-resistant.”

At Side Quest Psychotherapy, I provide recovery coaching and patient advocacy for people navigating eating disorder recovery, mental health challenges, neurodivergence, and intersex healthcare — with lived experience as the foundation of everything I do.

My Side Quest

My path to this work wasn’t a straight line. It was a series of detours, dead ends, and moments where the map I was handed just didn’t match the terrain I was actually on.

I entered eating disorder treatment as a young person and quickly learned that the systems designed to help me weren’t built for someone like me. I was autistic in spaces that didn’t recognize neurodivergence. I was intersex in spaces that didn’t have language for my body. I was labeled “complex” and “treatment-resistant” in ways that felt more like dismissal than clinical observation. I kept showing up anyway — and eventually found pockets of care that actually fit.

That experience is what drives everything I do now. I’ve spent over a decade advocating for intersex individuals and their families — co-coordinating youth programs, supporting people through identity and medical decisions, and showing up at the tables where decisions get made about people like us. Alongside that, I’ve spent the last four years working in the eating disorder field through peer support, research collaboration, and organizational work — learning how to translate all of that into something that actually helps people right now.

I bring lived experience and rigorous training to this work in equal measure. I’m not a therapist, and I’m not trying to be. My role is to be the guide who has walked some of this terrain before — who knows where the trail is unmarked, where systems will push back, and how to keep moving anyway.

Working With Me

I provide recovery coaching that meets you where you are. My work is practical, grounded, and focused on your needs. I collaborate with your existing care team when helpful, supporting you in advocating for yourself and managing the real-life challenges that traditional treatment often doesn’t address. My aim is to make life a little easier and help you move forward on your own terms.

My approach is HAES-aligned, weight-inclusive, neuroaffirming, and focused on reducing harm. I adapt to your nervous system and communication style rather than expecting you to adapt to a system. I am intersex-informed, with experience navigating the healthcare challenges intersex people face, and peer-grounded, drawing on my own lived experience as the foundation of my work.

If you’re ready for practical guidance, advocacy, and support tailored to you, book a session today and start moving forward with someone in your corner.

We Might Be a Good Fit If…

  • You’re autistic, ADHD, or otherwise neurodivergent

  • You’ve been told your eating disorder isn’t “serious enough” or you’ve been discharged from treatment before you felt ready, or you fall outside the diagnostic criteria that systems use to gatekeep care
  • You’ve been labeled “clinically complex,” “severe and enduring,” or “treatment-resistant”
  • You want real-world support alongside clinical care 
  • You’re intersex and looking for someone who gets it from the inside — whether that’s healthcare navigation, bodily autonomy, medical decision-making, or just finding language for your experience

  • You’re LGBTQIA+ and tired of explaining yourself
  • You’re a parent or caregiver supporting a young person through eating disorder recovery, or navigating intersex medical decisions on behalf of your child
