Luke Sullivan

Owner of Pinnacle Fitness/Certified Personal Trainer

Luke moved to Arizona in 2006 to pursue his dream of making the 2008 Olympic team as a discus thrower. Injuries ultimately hampered his training so, despite qualifying to compete at the 2008 Olympic Trials, Luke chose to listen to his body and prevent further damage. After dedicating 20 years to training and competing, Luke officially retired from competitive discus throwing in June, 2008.

Now Luke’s focus is dedicated solely on changing peoples’ lives through fitness. Using the success he created over the past (9) years of transforming personal-training clients of all body types, Luke launched Pinnacle Fitness.

Fitness has always been a part of Luke’s life. As a teen, he was a three-sport athlete in his hometown of Verona, WI. He used his athletic abilities to earn a full scholarship to UCLA to compete on their Track & Field team, eventually being named Team Captain in 1999 and achieving All-American status four times during his collegiate career with the Bruins!

Luke stays connected to his hometown roots in Wisconsin – his parents maintain their residency in Verona as does his older brother. He continues to develop young Wisconsin throwers through two annual throwing clinics and guest speaking engagements at schools and banquets.

Lorenzo Marino 

Certified Personal Trainer

Fitness has taken a huge leading role in my life. As a kid and a teenager I was considered
morbidly obese, and doctors would consistently tell me that I had to lose weight. And so with a
lot of trial and error I was able to lose over one-hundred twenty-five pounds! During this weight
loss journey I fell in love with the gym, and after some hard work and commitment I had finally
weighed in at under two-hundred pounds despite weighing over three-hundred at one point! I
regained so many things that I took for granted. I can tie my shoe without becoming out of
breath, run, and fit into clothes at the store. I wanted others to experience this freeing feeling.
So, I earned my personal training certification from the National Academy of Sports Medicine
and set out on my journey to become the best version of myself as a coach!
During my tenure at the gym I started competing in the sports of Powerlifting and Strongman.
This has given me an extensive knowledge of ways to strengthen and condition the body. But as
someone who was still rather heavy, I had to work around many injuries and deficits in the way
that I moved. Being so injury prone, I chose to earn my Corrective Exercise Specialization from
the National Academy of Sports Medicine, this allowed me to rehabilitate myself and existing
clients through movement!
My favorite things outside of work are spending time with my wife, keeping up with the current
trends in the world of strength sports, and DIY projects that go horribly wrong 90% of the time.
Even though I’ve lost a lot of weight, I still enjoy trying new and fun foods from time-to-time and
would love suggestions!

Nathan Vasquez

Certified Personal Trainer 

Nathan was born in Chicago, Illinois and comes from a big family with 2 older sisters and 3 younger brothers. Having a father who has been in the marines for 25+ years meant that the family has moved 6 total times throughout Illinois and California. During high school, Nathan was a 3-sport athlete athlete playing football, wrestling, and track & field all 4 years. Being active started at a young age, when he first started playing sports and his father took him to workout. Since then, remaining active active has been very crucial in his life, especially when he decided to attend Arizona State University.

At school he joined the powerlifting club, worked at the school gym, and was an intern at EXOS working with MLB athletes. Nathan earned his bachelor’s degree in Clinical Exercise Science in 3 years and his personal training certification through ACSM (American College of Sports Medicine).

ASU is also where he met his girlfriend who also graduated in 3 years, but in Criminology & Criminal Justice. This is who he loves to spend any free time he has with. Post-graduation he moved away from home in Chicago to get away from shoveling snow and was working at the Boulders Resort as a maintenance man since he loves working with his hands. Now, he couldn’t be any happier to be back in the gym environment and to be part of a crew with amazing clientele.
