What do you enjoy most about instructing?
What I enjoy most about coaching is helping kids reach their goals both mentally and physically. The process of teaching is what keeps me going. 

Who is your favorite type of client to work with?
I love to work with all athletes from beginners to professionals. The beginners come in wide-eyed and ready to learn, but the upper-level players can focus on the mental side of the game that is so under-appreciated.

In which area do you excel the most in your job?
I provide a ton of energy in my lessons. I like to focus on mechanics, but know when to let somebody loose and compete.

When did you start working for DiamondFit?
I started at DFP in September of 2014.

What baseball teams have you played for?
Sanderson HS ‘08
PittCC ‘10
Radford University ‘11-‘12
KC Royals ‘12-‘17

Tell us about any special talents or unique things about you that are unrelated to your career.
I love to quote any Will Ferrell movie and I can remember song lyrics better than anything I learned from math class.
