Rachael Weatherbottom

The Chemistry Whisperer
With over 15 years of experience in pool maintenance, Rachael knows water chemistry like the back of her hand. She started testing pH levels in her family’s pool business as a teen and later worked with resorts to perfect their water quality systems. Now, she develops our calculators to ensure they’re not just accurate—but actually easy to use. When she’s not balancing alkalinity, you’ll find her kayaking or explaining to her neighbors why their pool is cloudy (again).
Marcus Thornfield

The Pool Mechanic
Marcus spent a decade designing and installing custom pools before realizing most homeowners just want straightforward advice. He specializes in equipment efficiency—from variable-speed pumps to robotic cleaners—and breaks down complex systems into simple fixes. His pro tips have saved thousands in unnecessary repairs, and his calculator tools help you diagnose issues before they become disasters. Off-duty, he tinkers with vintage pool pumps (yes, really).
Lila Fairholme

The Clarity Coach
A former competitive swimmer, Lila has spent more time in pools than on land. She transitioned from coaching swimmers to coaching pool owners, teaching them how to maintain pristine water with minimal effort. Her troubleshooting guides and seasonal care plans are fan favorites for their step-by-step clarity. When not testing new pool gadgets, she’s probably convincing friends that saltwater pools aren’t “scary.”
