About Omni

Omni was co-founded by Corrie Van Horne and Melissa Preston, who are both Licensed Professional Counselors (Corrie is a candidate) and Registered Dietitians. Corrie and Melissa both worked first as dietitians but realized that supporting the whole person, rather than just the nutrition and food aspect of their client's experience was something they desired. That is what led them to pursue their counseling degrees.

Corrie and Melissa have over 25 years of combined experience. They came together to create Omni Counseling and Nutrition to provide a community resource and to serve as a space where clients can come to receive counseling support fused with nutrition therapy. Corrie and Melissa utilize Health At Every Size® and Intuitive Eating in their work with clients. 

Inclusivity is in Omni's mission statement and is a top value that guides their work. Everyone on Omni’s team honors each client as an individual and recognizes that every person has a unique story that has impacted who they are. Omni Counseling and Nutrition aims to be inclusive of people of all backgrounds and identities regardless of gender identity or expression, religion, race, ethnicity, sexual orientation, ability, size, class, political leaning, etc.

I was always told growing up that I was “too sensitive”. I thought this was a flaw and I needed more of a backbone. I’ve come to accept and embrace this because this is my gift that I give to you. My sensitivity means I probably know exactly how you feel. I’ve dealt with crippling anxiety and depression in the past, so when you describe these feelings to me, there’s a good chance I know what you’re going through. And if you try to use food or change your body to cope with these uncomfortable feelings, then I’ve definitely been in your shoes.

In 2005 after a 10 year battle, I recovered from my own eating disorder.  Clients report that my history of struggle and recovery helps them feel more fully understood, and gives them hope that a life without disordered eating is possible for them. And it is possible for you too! I have worked for 5 years combining counseling and nutrition and find it to be the best marriage for working with people with eating disorders. Omni’s mission of whole person nourishment is exactly what I do with clients in every session.

I am likely the most honest person you will ever meet. If you want a soft and fuzzy therapist that just wants to talk, I’m probably not your gal. My style is reflective, relational, and very action-oriented. I don’t want you to live one more second with your eating disorder. Let’s do this.

The loves of my life include my partner, friends, and perhaps most important, my dog Pepper (all you dog lovers know what I’m talking about). On the weekends you’ll find me hiking in the beautiful mountains of Colorado, cooking crazy concoctions in my kitchen, and trying my best to put my phone down and read a real book.

**My education and licensure: I have been a Registered Dietitian for 15 years (registration #RD 933352). I graduated with my Masters in Counseling in May of 2013 and I have been a Licensed Professional Counselor since May of 2015 (license # LPC 12455).

My journey to food freedom and body peace was often times slow and arduous, but the rewards are overflowing - I now have liberty, serenity, and acceptance in my relationship with food and my body. Through my own process, I have learned that we grow and heal in and through connection with ourselves and others. I love connecting with my clients and walking with you on your journey to recovery from eating disorders and addictions, and in the development of a better understanding of yourself.

My hope in working with you is that I can provide a safe space for self-exploration and growth. My approach is weight inclusive and holds a social justice lens. Through our relationship, we will examine the role stigma and oppression have had in your relationship with food and your body. My intention is to incorporate Omni’s philosophy of whole person nourishment into each of my sessions. We will work together on your journey to developing a peaceful relationship with food and movement.

It is my belief that food nourishes us in many ways and is also meant to be a source of pleasure, connection, and celebration (among many other things)! I believe that our relationship with food and our bodies is most health promoting when we let go of labels and control and begin to learn to relate in a way that honors our whole selves: mind, body, and spirit.

I am passionate about the work I do and also love my down time! Connection is my top value which means time with my loved ones - my family, friends, and my dog Roxy - is always recharging. Other loves of mine include taking advantage of the great Colorado outdoors, checking out any live music, or sometimes playing some of my own tunes. I guess some might call me a foodie too, as I have a weakness for trying out new restaurants and creating new concoctions in my kitchen. My favorite daily ritual is sipping a hot cup of coffee in the peace of the early morning. 

**A little about my education and licensure. I have been a RD for 11 years. I graduated with my Masters in Counseling in December of 2017, and I am now working towards licensure in the state of Colorado (candidate license # LPCC 15788) . Carmen Cool is my supervisor.

It is with incredible gratitude and great enthusiasm that I recently landed in Denver and found myself amid so many wonderful resources for helping people to work towards permanent recovery from eating disorders.  I am a Michigan girl at heart who followed her family West, and I am learning that the mountains can be as beautiful and soothing as the wonderful waters that are so much a part of my life in Michigan.  It has always been in nature that I have found the energy, direction, and motivation to seek ways to be useful in my work as well as my personal life.

 Years ago I chose to major in nutrition and dietetics because of my love of science and the link to health and wellness.  I entered into private practice early in my career, and quickly learned that I had A LOT to learn about eating disorders if I was going to ask clients to trust me with their innermost thoughts, feelings, and behaviors around food.  I have pursued advanced level training and supervision, in addition to taking two 40 hour training courses: “Diagnosis, Assessment and Treatment of Eating Disorders: A Multidisciplinary Approach” and “Treatment of Comorbid and Chronically Eating Disordered Patients”.  I knew after this education that I was “hooked” on the field, in part due to the severe need for understanding of the role of nutrition in cause as well as recovery, and also for the wonderful opportunity to work with clients on their “whole person nourishment “ as well as to work with their families and significant people that shared in the struggle and devastation that eating disorders had brought into their lives.

Things that I believe passionately: 

  • Full recovery is possible and worth the effort. (Half measures don’t bring freedom from ED). 

  • Freedom from internal obsession, rumination, and worry about weight, shape and appearance is something everyone deserves and is worthy of. 

  • Focus on beliefs and behaviors rather than body weight is the path to the aforementioned freedom as well as to optimal health. 

  • In a healthy relationship between self and food, there is no place for fear, judgment or guilt.  That would include no calorie counting, food weighing, or lengthy list of forbidden foods!

  • People that I love working with include:

  •  Chronic dieters who desperately want to give up old and unhelpful behaviors and learn to give themselves permission to eat adequately and with joy.

  •  Parents (Families) who want to raise children with positive and healthy relationships with food and weight.

  •  Individuals who desire recovery from their eating disorder, making a lasting transformation in their lives.

  •  I have experience working with colleagues from other disciplines to offer a team approach to adolescents, adults, and families.  I believe that you, the person reading this and considering entering into nutrition counseling with me, are the most important person on the team.

I am a therapist because I believe in the power of vulnerability, connection and sharing one’s story. My mission is to best support you as a whole person, including the systems you operate within and may be oppressed by. I believe so much of healing is engaging in the unlearning process. Unlearning stigma, unlearning to hate our bodies, unlearning inappropriate blame. I want to offer you a safe, compassionate space to do just that. Unlearning and detaching from hurtful stories opens up space for self love and acceptance.

 In my years of experience working in a variety of mental health settings two themes continue to show up in the room together; trauma and body shame. Research shows just how much trauma wreaks havoc on the body over time, often resulting in increased physical distress and shame. EMDR (Eye Movement Desensitization Reprocessing) is an evidence-based therapy aimed at alleviating distress and physical activation associated with traumatic memories. I use EMDR with clients whose trauma may be keeping them stuck in old negative beliefs or behaviors.  

 In addition to my trauma skillset I utilize Cognitive Behavioral Therapy and mindfulness to help clients work through uncomfortable emotions and potentially unhelpful thoughts or rules. My approach is informed by Health At Every Size and Intuitive Eating. I aim to be weight inclusive and create safety for people of all identities and backgrounds.

 When I am not working I tend to be a homebody that loves cooking, watching movies and doing yoga. Like most midwest transplants I am still in awe of this beautiful state, even 7 years later. I am the most grounded while in nature and feel grateful for easy access to hiking and camping. I try very hard to role model the work/life balance I want for my clients and their families.

 **I graduated with my Masters in Counseling in December of 2017 and am working towards licensure in the state of Colorado (candidate license LPCC #15799). Rick Kamins is my supervisor (Psychologist #1368). I was EMDR trained starting in August 2018. I am working towards certification and receiving ongoing professional consultation.
