REVVed: to have made something more active or energetic.
Seattle Registered Dietitian
You’ve tried everything…
To eat “better,” feel “healthier,” and fix your relationship with food.
Maybe you’ve counted macros, downloaded tracker apps, counted your steps, or even dipped your toe into intuitive eating.
But something still feels off.
You’re stuck in a loop: guilt… control… out-of-control… repeat.
I’ve seen that cycle. And I’ve helped hundreds break it.
As a registered dietitian, athlete, and mom, I work with high-performing professionals, overwhelmed parents, exhausted binge-restrictors, curious teens and college students… And people just like you who want something better without losing themselves trying to get there.
Our work is flexible, judgment-free, and based in evidence.
You don’t have to figure it out alone.
Behind the Scenes!
Who I Am
Hi, I’m Marissa Beck (and I really love food).
I say that because as soon as people find out I’m a dietitian, they assume I live off kale salads and protein shakes… and that I push that kind of nonsense on my clients, too. Sorry, Charlie, I eat all kinds of food, (including chocolate gelati, my favorite treat).
I’ve been a Registered Dietitian Nutritionist since 2009 and, over the years, I’ve worked with some of the biggest names in tech, supporting employees and their families through wellness and nutrition counseling. But eventually, I wanted more autonomy, and more impact.
So I started REVV Health to help people like you (and your loved ones) shift gears, break free from diet culture, and build a truly sustainable, feel-good relationship with food.
Originally from Queens, NY (Let’s go, Mets!), I now live in Seattle with my husband and our two amazing daughters (ages 7 and 10). I’ve been an athlete my whole life and still love moving my body in ways that are fun, freeing, and a little bit fierce.
My Philosophy
I believe that true health isn’t following rigid rules or seeking perfection, but rather, finding ways to feel nourished, balanced, and living 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 working 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 grounded in respect, ensuring that you are sincerely 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 break multi-generational cycles of disordered eating.
Why I do this work
I never thought I’d wake up and not feel like the scale dictated my day. That I could go a full day without counting every calorie or questioning every bite.
But here I am. And I want that for you, too.
I used to believe that control, that is, over my food, my body, my performance, was the key to feeling good. As a high-achieving college athlete, I chased perfection academically and physically while silently battling PCOS, IBS, and years of disordered eating. From the outside, I looked like I had it all together. Inside, I was exhausted.
Everything shifted in 2005. I had just qualified for the Boston Marathon when an injury forced me to stop. For the first time, I had to listen to my body. And I realized how much healing I had been avoiding.
That wake-up call led me to pursue a Master’s in Nutrition and Exercise Physiology. Not because I wanted to obsess over food more. But because I wanted to understand health differently.
And I did.
I learned that the goal isn’t perfect eating or perfect health. It’s trust. That’s at the foundation of REVV Health.
Now, I help people heal from the cycle of restriction, guilt, and over-doing it 24/7, so they can rebuild a relationship with food that actually supports their life.
As a mom, I model that for my own kids every day: enjoying ALL foods, honoring our bodies, and letting go of diet culture’s grip.
If you’re ready to stop chasing perfection and start living more fully – I’m here to help.

My Bio
Hi, I’m Marissa Beck!
I’ve been a registered dietitian nutritionist since 2009, helping people heal their relationship with food, quiet the perfectionism, and feel better in their bodies.
Before founding REVV Health on November 1st, 2022, I led nutrition programs at companies like Nintendo and Microsoft, and worked with employees at Google, Facebook and other tech companies. My corporate wellness career began in NYC, where I built and managed health initiatives at a fast-paced eCommerce startup. Whether I’m supporting a busy executive, an athlete, or a parent navigating family food dynamics, I bring curiosity, compassion, and evidence-based strategies to the table.
I earned my Master of Science in Nutrition and Exercise Physiology from Columbia University and hold a BA from Tufts. My approach is highly personalized, because even if the symptoms look the same on paper, your story deserves more than a one-size-fits-all plan.
As a former gymnast and collegiate athlete, I know what it’s like to feel pressure around food, performance, and body image. These days, I find joy in movement through Peloton rides, skiing, and hiking around Seattle, where I live with my husband and two daughters.
Outside of work, I’m a proud foodie who loves exploring new cultures through cooking and sharing meals with family and friends. To me, food should be nourishing, satisfying, and joyful…not a source of stress.
If you’re looking for expert support 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.”
