My coaching style

I strive to give clients the knowledge and understanding they need to make decisions about their food, exercise, and lifestyle patterns. I have a compassionate and direct approach with clients, and I love a Grade A food pun. I believe that health is defined individually, and can be achieved in any body. I am a proud ally of the LGBTQIA+ communities!

Fantastic experience! I look forward to my coaching sessions so much. Krissy not only supports me in my meal planning and macro tracking but also takes the time to teach me about the science behind nutrition. I feel like I’m learning so much.
