training career back in 2014. He loves helping
others achieve their fitness goals and building
new relationships. Drew truly believes that
fitness programs must be designed for the
individual rather than the group: “People
should be approached with an integrative
perspective in terms of lifestyle,
nutrition, and movement.” His goal in life
is to help many people reach their goals & to
create and nourish those relationships so that
they can last a lifetime. His ideal client is
someone willing to learn and humble enough to
attack their weaknesses and to be held
accountable.He was admitted to SCCC’s physical
therapy assistant program & worked as an aide
in a physical therapy clinic.He decided to opt
out of that program because He believes
he can make a larger Impact in the gym
