Our Staff


A graduate of CBC HS in 2003 Brad was a multi-sport athlete playing
baseball and basketball. Upon graduation, he went on a baseball scholarship to Quincy University in Illinois where he received all-conference honors all three years and was First Team all-Region and an All American as a Junior.

Drafted twice, in 2005 by the Houston Astros in the 31st round and again in 2006 by the Florida Marlins in the 12th round. He played for 6 years including two at AAA New Orleans before retiring after an arm injury.

For almost two decades Brad has been a private pitching instructor in the St. Louis area and a strength coach since 2012, owning his own business since 2015. He has worked with hundreds of athletes from the high school, college, and professional ranks. He has also helped coach with Bishop DuBourg High School during their state championship season as well as Webster University and St. Mary’s High School.

In the weight room, Brad has over 20 years experience on both sides of the equation, as a coach and a client. Having been an athlete for most of his life he has had access to some world class coaching. These opportunities to learn from the best in the business have helped him formulate his personal
philosophies and create the foundation for his career as a strength coach.

“My unique perspective, having been a client and a coach, allows me to see all sides of the equation. I know what works to be motivated and pushed as an athlete as well as what needs to be done as your coach. Having been a client allows me to understand the day to day struggles real people go through and how to help push through the tougher days!”

Ali Seoud

It all started when I was given a second chance. That chance was my parents sacrificing everything so they could come and live in a place where they believed their children would have endless opportunities for success. It is a reminder everyday for me to try and accomplish my goals.
With a 4.0 GPA, and making the All-Star team for my district’s soccer team, I graduated as a Student Athlete from McKinley CLA. Upon graduating high school with such accomplishments, I started looking for ways to continue studying while pursuing my passion of becoming a professional soccer player. I am now a student at Lindenwood University studying Exercise Science while playing competitive soccer.
I live every day trying my best and trying to be the best person I can possibly be. It may be true that as an immigrant you may have more roadblocks, but I try not to let that get in my way. I believe I am in a place where my goals can be accomplished.
I enjoy training because it feels like I am giving back. My ultimate goal as a trainer is to train athletes and help prepare them for what it takes to make it at the professional level. When I am not at S3 training members and putting smiles on people’s faces, you can find me playing competitive soccer.
