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.
For years, I thought if I just controlled my body enough, happiness would follow. I chased perfection as a competitive collegiate athlete: acing classes, dominating in sports, and climbing the career ladder.
From the outside, I looked like I had it all together. But inside? I was struggling. PCOS, IBS, and years of disordered eating had left me exhausted.
In 2005, I hit what should have been my peak: I qualified for the Boston Marathon and looked like I was in the best shape of my life. But when an injury from overtraining forced me to stop, I realized I was falling apart on the inside.
Something had to change.
That wake-up call led me to earn my Master of Science in Nutrition and Exercise Physiology, not just as a career path, but as a way to truly understand and heal myself. And in doing so, I discovered what I was never taught: the goal isn’t rigid control. It’s trust.
I now help people move up Ellyn Satter’s Hierarchy of Food Needs, because when their food foundation is strong —when food security, satisfaction, and variety are in place — you reach the top. And at the top, you eat healthfully because you genuinely want to, not because of guilt, fear, or control. That’s where freedom lives.
And what does life look like on the other side?
- It looks like waking up excited about the day ahead instead of worrying about what you ate yesterday.
- It means food fits into your life, not the other way around.
- You sit down to meals without guilt, enjoy food for what it is, and move your body because it feels good—not as punishment.
- Your body is no longer a problem to solve, but a home to care for.
As a mom, I’m showing my children how to:
- Embrace all foods
- Foster a healthy relationship with their body
- Reject diet culture’s toxic grip
Most importantly, I’m showing them what it means to truly live.
That’s why I created REVV Health.
My goal is to offer you what I wish I’d had: personalized, compassionate support that goes beyond the numbers on a scale. I’m here to help you build a healthy, lasting relationship with food.
Family has always been my anchor, and I know how powerful that connection can be. Whether it’s strengthening your own family’s bond through food or creating a supportive care-team when you need one, I’m here to help.
REVV Health exists because I know firsthand how damaging the pursuit of perfection can be. I’m here to help you find beauty and peace in your perfectly imperfect life.
Are you ready to start living that way?
Let’s make it happen.

My Bio
Hi, I’m Marissa, the founder of REVV Health, an award-winning dietitian, and a non-diet nutrition counselor with over 15 years of experience. My passion lies in helping people heal their relationship with food, rediscover the joy of eating, and feel better in their bodies… without the exhausting cycle of diets and perfectionism.
I’ve had the privilege of building and scaling nutrition programs for some of the biggest tech companies in the world.
Before founding REVV Health, I served as the Nutrition Program Manager at Nintendo through CareATC and as a dietitian at PRO Club, where I counseled and gave talks to employees of Microsoft, Google and Facebook. My journey in corporate wellness started as the Director of Wellness at Next Jump, a New York-based eCommerce startup, where I managed wellness platforms, developed programs, and created engaging health content.
Throughout my career, I’ve counseled thousands of individuals, from busy professionals to parents looking to break free from diet culture and create healthier family food dynamics. My approach is rooted in compassion, curiosity, and evidence-based practices, blending the science of nutrition with real-life strategies that actually work.
I earned my Master of Science in Nutrition and Exercise Physiology from Columbia University and my Bachelor of Arts from Tufts University. But beyond the degrees, what truly shapes my work is being able to assess the problem in front of me. No two cases are the same, and even if on the surface the issues appear similar, the approach and treatment will be different. This ability to understand the unique context of each person’s experience is what guides my work.
As a former gymnast and collegiate athlete (field hockey, track, skiing, and lacrosse, and half-marathoner), I understand the pressures that come with performance and body image. These days, I find joy in movement through activities like Peloton rides, skiing, and exploring the beautiful outdoors of the Greater Seattle area, where I live with my husband and two daughters.
Outside of work, I’m a foodie at heart. I love discovering new cultures through food, experimenting with recipes, and sharing meals with family and friends. I believe food is more than fuel: it’s family, tradition, and a source of comfort and joy.
If you’re looking for support to feel better in your body, whether it’s through 1:1 non-diet counseling or a group talk with your team (corporate, athletic or small group) I look forward to connecting!
“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.”
