What is a Health Coach?

As the new owner and coach at Diet Mentor, I'm incredibly honored to carry on something that has meant so much to my family and to the many clients who have trusted Diet Mentor over the years. I took over the business following Sheri's retirement in July 2026, and I'm excited to bring my own passion for coaching to the next chapter of Diet Mentor.

Kaitlyn Fedele

Owner

My own experience with weight management is a big part of why I believe so strongly in this program. I've tried diets, restricted, pushed myself, felt frustrated, and wondered how I was ever going to make lasting changes. I know what it feels like to feel stuck, and I also know what it feels like to finally find something that works for you.

That's why my approach to coaching is rooted in compassion, honesty, and absolutely no judgment. I want my clients to have a space where they can be honest about their struggles, celebrate their successes, and work through the challenges one week at a time.

I truly believe that everyone can get to where they want to be, we just don't all get there in the same way or on the same timeline. I'm here to help you find what works for you and support you along the way.

Previous Owner & Coach

Health Coaches partner with clients seeking self-directed, lasting changes, aligned with their values. This promotes health, wellness, and well-being. In the course of their work, health coaches display unconditional positive regard for their clients and a belief in their capacity for change, honoring that each client is an expert in their life, while ensuring that all interactions are respectful and non-judgmental.

Sheri Zillioux

Previous Owner

In 2008, I was diagnosed with breast cancer and then again in 2010 which required multiple surgeries. Then in 2014, I was considered clinically obese and my doctor told me for the first time in my life I had high cholesterol, high triglycerides, was pre-diabetic, and had a fatty liver. I was also not sleeping well, started having a lot of migraines headaches, and was stressed out! I knew my diet was to blame. I was also asked in front of a group of co-workers when I was due, but I was not pregnant!

In December 2014, I started my weight loss journey and by May 2015, I had lost 42 pounds! All my blood work is now normal and I no longer suffer from migraines or feel stressed out due to lack of sleep. I take no medication. This was by far the easiest, healthiest diet I had ever done (and I've done them all)! I was not hungry and had a lot of energy.

I opened Diet Mentor to help others lose weight and teach them how to keep it off!

Information Processing

I have worked in healthcare my entire life starting out as a medical and insurance transcriptionist. I then moved on to become the Practice Administrator for two area medical practices for many years managing all areas of both practices. I realized I wanted to be more hands-on helping people learn to live a healthy lifestyle so I opened Diet Mentor in 2016.

All of our coaches have a passion for health and wellness and strive to help people make a difference in their health through their weight loss journey. Although we strive for you to meet with the same coach each week, there are times you will be seen by various coaches throughout your weight loss journey due to time off.

Thank you for choosing Diet Mentor as your weight loss service provider!
