REVVed: to have made something more active or energetic.
Registered Dietitian
When you’ve hit that breaking point with food and your body…
Don’t start another fad diet.
You deserve a seasoned registered dietitian who’s helped someone just like you, from the corporate world to the everyday challenges of family life.
Whether you’re an adult or teen seeking 1:1 Nutrition Counseling, a family needing guidance through Family Nutrition Counseling & Eating Support, a company looking to improve employee well-being through Workplace Nutrition, or someone ready to break free from a weight-centric mindset and finally “feel normal” around food again, I’m here for you.
And I don’t just mean in a “let’s fix your plate” kind of way. I mean in a “let’s laugh, cry, and dig deep to find what really works for you” kind of way.
Our work together will be evidence-based, non-diet goodness, wrapped up in services that are flexible to fit your needs.
Behind the Scenes!
Who I Am
Hi, I’m Marissa—and I really love food. I say this because as soon as people discover that I’m a registered dietitian, they tend to assume that I survive on kale salads and celery juice alone and prescribe these kinds of nonsense to my clients. Sorry, Charlie: I like (and eat) all kinds of food, including chocolate gelati, my favorite treat.
I’m a Seattle-based Registered Dietitian Nutritionist with 15 years of experience. In my tenure as a dietitian, I’ve worked with some of the biggest names in tech, supporting employees and their families. But in order to have more autonomy to better help my clients, I built REVV Health to help you and your loved ones shift gears, break free from diet culture, and build a healthy, joyful relationship with food.
While originally from Queens, NY (Let’s Go Mets!) I love my home and community here in Seattle, Washington (Go, Seahawks!). I’ve been an athlete my entire life and love being a parent with my husband to two amazing girls (ages 7 and 9).
My Philosophy
I believe that true health isn’t about rigid rules or perfection; it’s about nourishment, balance, and enjoying life to the fullest. My approach is rooted in the belief that all foods can have a place in your life, and that health is about far more than the number on a scale.
Client 💗, Features, & Speaking
Throughout my career, I’ve been a guest writer in a number of publications, including Today’s Dietitian, Eating Well and Seattle’s Child to name a few. I have also had the honor of speaking with the amazing employees of Microsoft, Nintendo and many local corporations and non-profit organizations.
“You really have a talent to bring nutrition education into a format that is easy to understand and motivates me to try to hit tricky goals, like fiber, that I’d otherwise not think about. I really appreciate your down to earth, no fuss advice!”
— Daisy P.
“Working with Marissa Beck at REVV Health was a superb experience. She is professional and organized. She was also responsive and considerate to her audience, tailored her presentation to the needs of our group, and knowledgeable as well as passionate about nutrition. I would highly recommend her and hope our group can partner with her again for future educational engagements.”
— Marcy Park, NYHS Instructor
“Marissa!! You’ve taught me so much about nutrition and made me happier and healthier over the years. I’m in a much better place because of your coaching program and monthly check-ins. Thank you!”
— Davis K.
My Values for Our Work Together
Compassion
This is a no-judgement zone. I understand the deep struggles with food and body image that many people face and approach our work together with compassion.
Authenticity
My goal is to empower you to build a healthy and joyful relationship with food, your body, and yourself.
Balance
Health is about more than just physical appearance. Balance in life, food, and body is a core value that underpins my approach.
Growth
I believe we all have the power to change, evolve and am committed to cultivating your growth-mindset.
Inclusion
Everyone, regardless of background, body size, or life experience, deserves support. My approach is rooted in respect, ensuring that you are authentically seen, heard and your experiences are believed.
Family
As a parent, I am deeply committed to raising the next generation with a healthier relationship with food to breaking multi-generational cycles of disordered eating.
My story
I never thought I would wake up and not feel like the scale dictated my day. That I wouldn’t need to count every calorie, track every gram, or feel trapped in a self-made prison of food rules and body judgments. But here I am: free.
And I want that for you, too.
I used to believe that control—over my body, my food, my performance—was the path to happiness. I was a high-achieving collegiate athlete chasing perfection, all while silently battling PCOS, IBS, and years of disordered eating.
From the outside, I looked like I had it all together. But inside, I was exhausted.
In 2005, after qualifying for the Boston Marathon, an injury forced me to stop. That pause made me realize how much I’d been ignoring my body’s needs—and how much healing I truly needed.
That wake-up call led me to pursue a Master of Science in Nutrition and Exercise Physiology. I didn’t just want to understand health—I wanted to live it differently.
I learned the goal isn’t rigid control. It’s trust.
That’s the foundation of REVV Health. I help clients build a peaceful, nourishing relationship with food and their body. Because when your food foundation is solid—when satisfaction and variety are part of the picture—you eat well because you want to, not because you “should.”
As a mom, I’m modeling that freedom for my kids: embracing all foods, honoring our bodies, and letting go of diet culture’s grip.
If you’re ready to stop chasing perfection and start living fully—I’m here to help.

My Bio
Hi, I’m Marissa — a Master’s-trained dietitian with over 15 years of experience helping people heal their relationship with food, break free from perfectionism, and feel better in their bodies.
Before founding REVV Health, I led nutrition programs at companies like Nintendo, Microsoft, Google, and Facebook. My corporate wellness career began in NYC, where I built and managed health initiatives at a fast-paced eCommerce startup. Whether I’m working with a busy executive, an athlete, or a parent navigating family food dynamics, I bring curiosity, compassion, and evidence-based strategies that actually work.
I hold a Master of Science in Nutrition and Exercise Physiology from Columbia University and a BA from Tufts. My approach is highly personalized—because even if the issues look the same on paper, your story deserves more than a one-size-fits-all solution.
As a former gymnast and collegiate athlete, I understand the pressure to perform and the complicated feelings around food and body image. These days, I find joy in movement through Peloton rides, skiing, and hiking around the beautiful Seattle area, where I live with my husband and two daughters.
Outside of work, I’m a proud foodie who loves discovering new cultures through cooking and sharing meals with family and friends. I believe food should be nourishing, satisfying, and joyful—not a source of stress.
If you’re looking for expert support—whether for yourself or your team—I’d love to connect.
“Marissa is amazing. She is empathetic to all the realities of life when it comes to eating in any stage of life. I found her in conversation about my weight struggles for menopause. She said she had tools and I said YES PLEASE. My biggest fear was moving from a M to a L in my shorts. After hiring her, I actually love and have confidence in my body at any size.”
