I’m John. I’m a physical therapist, swimmer, strength coach, and swimming researcher in Santa Clara, California.
I personally love the sport of swimming and started this website while receiving my doctorate at the University of Southern California (USC). At USC, I came across scientific articles on the sport of swimming which I found fascinating! After finding these, I decided to start a blog and share them online. Since then, the website has expanded and now we have an amazing group of contributors from all over the world, which all have the love of swimming and wish to improve the swimming community!


I swam my whole life, starting at the age of 4. I was lucky enough to receive a swimming scholarship to Purdue University. At Purdue, I started in Chemical Engineering, before switching to General Health Sciences. After swimming at Purdue, I coached shortly in North Carolina, before starting my Doctorate program at USC. At USC, I did some research on lung capacities and worked with many high level athletes. After graduating, I moved to Santa Clara, CA to be with my current wife (who is also a swim coach) and began doing dryland programming and physical therapy. I currently have my own physical therapy and sports performance center in Santa Clara, CA (www.trainingcor.com) and consult with numerous college and club swim teams.
If you are interested in having me work with your team or consult with you, please email us at info@swimmingscience.net.


The goal of the Swimming Science website is to educate, entertain, and improve the swimming community. We help bridge the gap between the scientific, theoretical, and practical world of swimming with our various online channels and with our diverse group of contributors.
Please feel free to subscribe to the newsletter below and get exclusive content that you cannot find here on the blog, as well as free information on how to take your swimming to the next level and the #1 dryland mistake!
