My Mission

My mission is to empower clients to live the healthy lifestyle they aspire to. Knowing that this is different for everyone to achieve, maintain and improve upon, I will listen, provide feedback and ultimately individualize client's plans to meet their goals while having fun and learning!

"The secret to getting ahead is getting started."

Why Train With Me

Colleagues describe me as having a non-intimidating demeanor. When starting a workout plan or health journey, you want to feel comfortable and have a coach to not only guide you, but to teach you the "why" behind the nutrition and exercise suggestions. That coach can be me! When you need motivation, have a question or need ideas, I can help problem solve and get you back on your feet!

My go-to workout

My tried and true workout is running. I also like HIIT and strength training.

Healthy food I love

Berries, cottage cheese, mushrooms and chicken of any kind!

Healthy food I hate

You won't find me eating any raw fish!

Client stories

"Before finding Kickoff, I wasted so much time sitting in my car at the gym trying to google the "best" workout for the day. Now I never fret over workouts - they're sent to me with clear instruction in the Kickoff app. Working with my trainer via text has been such a benefit. Having that accountability was key - I beat my goal by 10 lbs, losing 40 lbs before my wedding day!"
