Testimonials

"Erika has been wonderful since day 1. Right away she got to know what my struggles, obstacles and concerns were and she dove right in with an assessment and a plan. I initially chose her because of her friendly and warm disposition and extensive educational background. She is incredibly knowledgeable and a great teacher. She is never judgemental and is very understanding, passionate about what she does and kind. She has been guiding me through my journey step by step and I have seen consistent progress weekly. Within the first week I lost 5 lbs and my mental health and well-being drastically improved. Her expectations are realistic and grounded in science but she is also very human and makes eating well fun as well as comfortable and healthy. She was the light I needed after the toxic diet fads I was exposed to on social media. She has shared a wealth of knowledge as well as beautifully made recipe cards that have been significant in me staying motivated and organized. It truly feels like I’m talking to a trusted friend and she is one of the nicest people I’ve ever met. She is so flexible and accommodating with her time and resources and makes herself available and engaged. I can’t recommend her enough! Thank you Erika for helping me find hope and supporting me at a time when I thought it would be impossible to get better."

"Erika was super knowledgeable about approaching a new diet that ultimately fixed the issues I had been having for years. She was professional and responsive throughout, whether via Telehealth video chat or messaging. If I ever have the chance to refer her, I will."

- Kyle H.

"Working with Erika has granted me understanding and complete control over my diet. I have tried countless programs, trendy diets, and even fasting routines. Nothing worked long term. Her advice and guidance has helped change my life forever. Her sustainable and professional guidance has proved to be invaluable to my overall health. I feel the overall level of care, ability to customize strategies that worked for me, and professionalism separates her from others."
