About the Swim Stroke Doctor Underwater Video System:

Swim Stroke Doctor was founded during the summer of 2012 by Dan Lynch of Indian Head Park, IL. Dan is a graduate of the University of Illinois with a degree in Finance from the College of Liberal Arts and Sciences. Dan swam for a year at the University under Head Coach Don Sammons, and four years at Lyons Township High School, LaGrange, IL under Coach John Weber and Coach Don Holubec. Dan’s business background is Product Development, Quality Control, International Sourcing, with additional background in Sales and Marketing.

Dan is a USA Swimming Referee and a member of the CSOA, College Swim Officials Association. Dan’s vision is to reinvent swim coaching using Visual Learning. Today’s student athletes are digital natives and visual learners and this allows the creation of a new method to study the underwater technical aspects of swimming.

As a past president of the Chicago area Intersuburban Swim conference, Dan believes in the importance of swimming and the positive effect it has on children’s lives. Dan uses a phrase often to describe the importance of swimming for children, “Swimming is a Life Sport, we are here for the kids.”

The Swim Stroke Doctor, LLC high performance swim video analysis was first tested in the summer of 2012 at the LaGrange Field Club, in LaGrange, IL.  Head Coach Scott Gourley of the LaGrange Field Club, and Morton High School thought it “provides a new and exciting perspective to the analysis of the swim stroke”. The Academey Bullets swim team was the first to offer pool time for in-water testing and development, thanks to Coach Mike Laurich Head Site Coach. Please see our testimonials section for additional comments.

Our first system was placed in 2014 to Grove City College, Grove City, PA  Head Coach Dave Fritz. We have recently installed a system at The Ohio State University for Head Coach Bill Wadley and the Bucs swimmers. We have done video analysis for 2012 Olympic Trials qualifiers, Brian Donatelli ( U of Iowa), Mimi Schneider (2012 All-American Fenwick H.S. and Academy Bullets, IL State Champion 100 fly), and several top Academy Bullets swimmers including Paulina Kaminski (2012 All-American Fenwick H.S., IL 100 Breast), as well as  many age group swimmers at clubs like the Academy Bullets Swim Club and the Hornet Swim Club.

In high performance competition, it is said, “fast kids make records.” While we certainly cannot dispute this claim, “kids with effective coaching, proper swim technique and desire set records.”
