Marissa Campbell, MS, RDN, LD


I am an anti-diet dietitian, Mainer, and overall bubbly person with a Master’s degree in Nutrition from the University of Maine. 


Thinking back on my relationship with food growing up, it undoubtedly had its ups and downs. One of the most challenging times was in middle school. My middle school friend group became toxic and so did my relationship with food and my body. Thankfully, things changed entirely for me when I went to high school. New friends, activities, and academic challenges all shifted my focus way from food and exercise and I didn’t look back.


Until college. I am beyond thankful for my education but graduated with a degree in nutrition and an empty feeling like nothing I learned sparked a fire in me. Not the study of metabolism. Or trace minerals. Or food service. But, then I came across intuitive eating and Health at Every Size and my world opened up. Everything just made sense. 


After graduating with a master's degree, I knew I needed to help pave the way in Maine and help people to break-up with diet culture and heal their relationship with food and their body. Because if there’s one thing I know, it is that there is space for us all here.

And when I’m not working, it’s almost guaranteed that I’m snuggling my two cats, Milo & Oats, taking walks outside with my friends or family, laughing at random puns, or eating cheese.

Lauren Costello, MS, RDN, LD

I am an anti-diet dietitian from Western Massachusetts looking to empower patients through nutrition.


I graduated from Saint Michael’s College with a bachelor’s degree in biology and from the University of Massachusetts, Amherst with a master’s degree in nutrition. I then went on to complete my dietetic internship at Beth Israel Deaconess Medical Center in Boston. I have experience as a GI dietitian, where my main focus was providing patients with tools and support they needed to stay safe and nourished.


Along my personal and professional journey, I have seen patients and friends struggle with diet culture-- but I think that we all do at some level. I believe we are all born intuitive eaters, and in order to return to this, we must heal from the messages thrown our way by diet culture and remember how to trust our own instincts and experiences.


During my dietetic internship, I also nurtured a love for GI nutrition and have seen that for those with GI disorders, intuitive eating practices can be integral to finding peace with food as well.


I believe in celebrating the little victories on the way to finding comfort and trust with your body and self compassion throughout this process. I am absolutely thrilled to work with a team of social workers and dietitians who share the philosophy of empowering all patients through nutrition.


When I am not working, I enjoy spending time playing with my rescue dog, Mia, horseback riding, skiing, and hiking.

Karen Fisher, LCSW

I earned a B.A. from Hobart and William Smith Colleges and a Masters in
Social Work from Boston College Graduate School of Social Work. I have
worked as a Licensed Clinical Social Worker for over thirty years providing
clinical counseling services to individuals, couples, families and groups. Much of my clinical work has been focused on eating disorders and assisting clients in exploring their relationship with food. I am a supporter of the HAES model and believe that self compassion is at the foundation of all healing.

I am certified as a Am I Hungry? TM Group Facilitator which utilizes principles of Cognitive-Behavioral Therapy and Mindfulness techniques to examine the emotional reasons we use food to cope with difficult feelings and allows us to get back in touch with our internal cues of physical hunger and fullness. Most recently I have become a CDWF (Certified Daring Way Facilitator TM ) after training with Brene ́ Brown, PhD. and her team. The primary focus of The Daring Way TM is on developing shame resilience skills and developing a courage practice that transforms the way we live, love, parent, and lead. I have woven my educational background together to focus on the client as a whole, believing that wellness reflects the mind, body and spirit of every client I work with.

On a personal note, I am a connector. I love people and conversations and enjoy assisting others in making positive change and forward movement in their lives. I feel I am equal measures head and heart. You will be greeted with compassion, warmth and reason, with some humor mixed in for good measure. Some clients believe that as a counselor I must not struggle or have personal problems. Oooh, how I wish! To be human is to struggle and we all have personal problems from time to time. I am real and accessible to my clients. I am not an expert. On anything. On disordered eating, fitness, trauma, identity, shame and relationship issues, parenting, addiction, grief, etc. Yes, I have a lot of training, experience, certifications, etc. but I do not know more about you than... YOU. I can assist in helping you find the power to heal and move forward . Together our combined strengths and knowledge is a catalyst to help you achieve your goals. Sometimes it takes all the energy you have just to show up. And on those days, that will be your victory. Other times, we will celebrate together your feeling that you can move mountains. Bottom line: You are enough. You are worthy. You are perfectly imperfect and wonderfully made.

Alyssa Russell, MS, RDN, LD

Originally from the North Fork of Long Island, New York, I received a bachelor’s degree in Psychology from the University of Vermont and went on to complete a master’s degree in Nutrition, Healthspan and Longevity from the University of Southern California. I first learned about intuitive eating during an internship experience at a clinic in Los Angeles, and it

opened up an entirely new perspective for me as a dietitian. Like so many of us, I’ve felt pressure from diet culture to look certain way and I’ve seen the same effect in many of my family members, friends, and patients.

Moving into an anti-diet mindset has guided me into an area of nutrition that I’m proud to be a part of. I’m excited to be working in a setting that allows me to help patients get in touch with their inner intuitive eater, feel at home in their bodies, and cultivate self-love.


In my free time, I can be found exploring Maine, spending time in nature with my husband and our two rescue dogs, Otis and Mo, and playing the clarinet.


Rebecca Smith, LCSW


I believe that the healing that occurs in therapy forms and grows from the relationship between the client and therapist. My work is rooted in connection, compassion and empathy. I believe that each of us is the expert on ourselves and our path, and the therapist’s role is that of a supportive guide through our own individual journeys.


I discovered the Health at Every Size and intuitive Eating models years ago at a stage in my individual journey where I realized that I had a choice to make. I could continue on the path that diet culture had laid out before me: one of restriction, scarcity and shame, or I could reject it and choose intentional, hard-won joy instead.  In my own, irreverent words at the time, I could keep striving for thinness at all costs, or choose instead to live, “free, fat, and happy.” Choosing to live joyfully in a larger body hasn’t always been easy, but it has always been worth it. 


Professionally, I have utilized my passion for mindful self-compassion, body positivity, and fat acceptance to support clients of all ages, sizes, and backgrounds in discovering their self-worth and capacity for joy. After receiving my Master’s degree in Social Work from the University of Southern Maine I went on to treat children, adolescents and adults with a variety of mental health concerns in community-based settings. Through that foundational work a passion for understanding and treating the lasting effects of trauma emerged. I’m trained in both Trauma-Focused Cognitive Behavioral Therapy and the Attachment, Regulation, and Competency models for trauma treatment. I believe that exploring, understanding, and healing the effects of our past can empower us to shape our future. 


In my spare time, I’m a true home-body who loves nothing more than to stay in with a good book and a great cup of coffee. When I do venture out, I love spending time outdoors exploring Maine’s lakes, beaches and parks with my family, or, in the warmer months, hitting the local nursery to find the perfect addition to one of my flower or vegetable gardens.
