Simon’s Story

The Challenge

Simon decided to pursue a career in the United States Navy as an Aircrewman. Simon was in excellent mental and physical shape scoring excellent marks on the initial written tests. He consistently did morning PT in preparation for the Navy but there was just one series of physical tests that Simon knew he might need a little help with passing. It was a series of advanced swimming tests.
Oh, he could swim just fine and had all his life… but this was a little different. If he chose the route of the Navy’s Aviation Resuce Swimmer, he would have to prove himself extremely competent in the water. 

Simon needed to swim 400 meters in under 11 minutes, jump in the water in full flight gear and swim 15 meters underwater, stay afloat treading water and swimming for a full 10 minutes, and display proficiency in four strokes.

How Swim423 helped prepare Simon

Simon contacted Swim423 to inquire about assistance with the challenge he had before him. A plan was made after carefully reviewing his goals.
Simon was always eager to learn and diligently showed up each week.
With consistent hard work, lots of time working on stroke technique, many video tutorials including videos of Simon underwater, Simon’s confidence grew!  No doubt Simon will pass all of his future swim tests with flying colors! GO SIMON!

Imagine seeing your swimming technique for the very first time after decades! That was Bob’s experience. Underwater video wasn't around during his high school years and that’s where Swim423 comes in with professional video stroke analysis. Watching himself in HD on a big screen was a total revelation. After carefully studying his swimming strokes through crystal clear video clips, Bob and Swim423 made some vital changes to his technique. The result? A significant boost in his speed through the water and another State Gold Medal in 2025! For more on Bob's story read on...

It's a story of perseverance and a powerful comeback. In his 70s, Bob, a former high school swimmer, decided to dive back into competitive swimming. After a remarkable win at the 2024 Tennessee Senior Olympics, he connected with Swim423 to prepare for his next challenge: the 2025 Senior Olympics. His plan was bold—win at the state level again and head to the national championships in Des Moines, Iowa. Thanks to his incredible hard work and fantastic technique, Bob’s dreams became a reality. His journey is an inspiration to all

Having contacted Swim423 in early spring of 2025, I worked with him to get him prepared for the summer league swim season. He exhibited excellent dedication and was quick in his learning. This summer at the Chattanooga City League Championship, Gio made the finals in several events and even won the High Point Award for his age group! 

Look at him go… Go Gio!

Joshua’s Story

A future US Air Force Special Ops overcomes fears!

When Joshua first called Swim423, he asked if I taught adults how to swim.  Then, with some anxiousness and quivering in his voice, he said “actually, I’m afraid of water”.

Joshua is entering the US Air Force and has the honorable desire to be a part of the Special Operations Command which has many physical tests that must be passed before becoming Special Ops, including a swimming test. Joshua is a former wrestling champion and an MMA fighter. From the photo, you can see that he will pass all the land tests for sure!


It has been my honor and privilege to work with Joshua over the past couple of months. As I got to know him a little better, I found out that he had a couple of near drowning experiences in the water as a child that left him very afraid of getting back into the water.  He is now 19 years old but hasn’t been swimming until he recently reached out to Swim423. 


Not only has he overcome his previous fear of water, but he is swimming down the pool with ease. He still has some work to do to be able to swim 500 yards and tread water for three minutes, but he has a great start now.

Congratulations Joshua!!!

Martyn’s Story

Learn to swim for the first time or learn to swim better with Chattanooga Swim School.

Martyn’s Story

Martyn came to the United States recently to make the most of economic opportunities.  He grew up in a very crowded city and had no pool access and had never learned to swim.

On his bucket list of things to do was to learn to swim without fear and with confidence.

His first session here at Swim423 was a difficult one for him as he struggled to be comfortable putting his head under water.  He has since advanced quickly and he shows off his new skills in the video below.

He will be rejoining his wife and family back in China soon.

Go Martyn!
