His functional fitness focus training started in 2015 when he started doing CrossFit. Tim was introduced to CrossFit by a friend that encouraged and pushed him towards CrossFit by explaining how close movements are/prepare him for his job as a firefighter. After years and years of putting it off Tim finally went in early 2022 and got his L1 certification. Tim has been a firefighter for 9 years and a full time firefighter for 5 years. Tim loves to see athletes evolve and become a better version of themselves everyday. He currently lives in Delaware with his wife, Caiti, and their two boys Liam and Tucker.

Annie Schertzer coach at Burg CrossFit Sunbury

Nutrition Coach

Annie Schertzer

Hello! My name is Annie and I am your Nutrition Coach at Burg Crossfit Sunbury! I have 2 daughters and a husband. My girls are 10 and 13 years old. My German Shepherd, Murphy is 6 years old, named after Michael P. Murphy, Navy Seal.

I’ve been doing CrossFit for 10 years – I started with a Groupon when I was 8 weeks, post-partum with my 2nd daughter. I planned on only doing CrossFit to lose my baby weight. As a former athlete, I fell in love with the sport and never plan on stopping. I meet each client where they are and work with them first to create good habits to help them reach their goals. I want to understand how they spend their day, how much they move their body, what their stress levels are, and how they sleep. I am not a nutrition coach who will just hand out calorie goals. I want to help create healthy habits that will not only improve their nutrition but their life as a whole.
