Welcome to Haven Nutrition!
I’m so glad you’re here. If you’ve found your way to this space, you may be longing for a different kind of relationship with food, your body, or your health—one that feels grounded, compassionate, and sustainable.
That’s what this space is about. I help people rebuild trust with their bodies, quiet the noise of diet culture, and find more ease and freedom with food and movement.
Meet Marni Mackey, RDN, LDN
For the past 10 years, I’ve had the privilege of walking alongside people from all different backgrounds on their journeys with food and health. Over time, my passion led me to specialize in supporting those navigating eating disorders and disordered eating.
My approach is compassionate, non-judgmental, and grounded in the belief that healing your relationship with food is possible. Together, we’ll focus on building trust with your body, finding balance, and creating a path toward peace with eating.
I grew up in New Jersey, where my love for food, nutrition, movement and helping others first began. After earning my B.S. in Nutrition and Dietetics from Syracuse University and completing my dietetic internship, I spent over a decade working with clients — from treatment centers to outpatient settings — before starting my own practice.
These days, I’m happily settled in West Chester, PA with my husband, our two kids and our dog, Diego. Life is full, busy, and filled with plenty of fun (and snacks!).
When I’m not working with clients, you can often find me teaching Pilates reformer, practicing mindful movement through exercise, venting to my mom friends, or sneaking in a little reality TV downtime with the hubby.

Client Reviews
“I've been working with Marni for awhile now and she has been a massive support in my eating disorder recovery. She is attentive, compassionate, educated and knows when to push/challenge.”
“I love Marni!! She’s been helping me build structure around my meals and it’s not only helped me but the rest of my family!! Can’t thank her enough!
“Love my sessions with Marni! She is so knowledgeable and I know that, with her, I’m in a safe space. I’ve been a patient for a year and a half and it’s been consistently easy for me to get appointments and begin to heal.”
“I’ve struggled with binge eating disorder for most of my life, and working with Marni has helped me arrive at a genuine place of peace with food and my body. I now find myself navigating triggering moments with self-compassion (and even humor!), and although my relationship with food can still challenge me, it no longer feels like a battle I’m destined to lose. Marni’s nonjudgmental, deeply therapeutic approach has brought me to a place I once thought was impossible.”
“I've had a wonderful experience meeting with Marni. Scheduling and communication have been really easy and in our sessions I feel like I have gained a really different perspective on my eating. She creates a really comfortable environment where I've been able to open up about all the areas of my life that contribute to my issues with eating. Highly recommend!”
“Marni has really helped challenged me while still showing empathy. I don’t know I would’ve been able to take these big steps in recovery without her.”
Let’s start with a complimentary consult call — no pressure, just a chance to connect.
