Hank: President & CEO
Hank Thompson was born to build amazing pools. As a 12-year-old, he watched with fascination while his neighbors built an intricate custom pool—and fell in love with the way the backyard was transformed. As he watched, he copied their construction phases in his own yard and built a small pond for his ducks. Then, while studying business at Texas State University, he worked construction to put himself through school and learned the fundamentals of building in the unique Hill Country landscape. When he finished school, he and his soon-to-be wife Theresa started Cascade Custom Pools, and it’s been his passion ever since.
In the last 40 years of serving Austin and the surrounding area, Hank has been hands-on with his clients, personally checking each step of construction to ensure the highest level of quality. His goal is for every pool—from the smallest to the grandest—to enrich the lives of the family using it. He has a special talent for some of the most challenging designs, including hillside construction and other difficult build sites.
Hank is grateful to be able to spend his time working in the pool industry with his wife and son, TJ. When not building pools, he enjoys his time managing wildlife on his Hill Country ranch, listening to country music and riding his Harley-Davidson.

Additionally, TJ boasts a plethora of certifications from leading manufacturers, underscoring his dedication to maintaining the highest standards of craftsmanship.

These designations represent the highest levels of education in swimming-pool engineering, construction, and watershape design, requiring hundreds of hours of advanced training in hydraulics, structural engineering, materials science, and architectural design.
Beyond the confines of his professional endeavors, TJ’s zest for life finds expression in his passions beyond the pool. An ardent music lover, he attends frequents concerts.

Throughout it all, she continued to guide Cascade’s finances, and as the company has grown, she has returned full‑time to help lead its next chapter.
Theresa loves being part of a family business and building something meaningful together. Outside of work, she enjoys yoga, traveling, and spending time with friends and family. Theresa (also known as GiGi) is finally a grandma to beautiful little Rowan and has a grandson on the way.

Jason Ellis, Master CBP, CPI: Senior Project Manager
My professional passion is turning ambitious backyard concepts into well-executed realities. I work closely with homeowners, builders, designers, engineers, subcontractors, and suppliers to solve the day-to-day challenges that can slow down or compromise custom construction. Whether that means resolving field conflicts, protecting schedule momentum, coordinating specialty trades, or catching critical details before they become costly problems, I approach every project with a practical, detail-driven mindset and a strong sense of accountability.
Before my time in construction management, I served in the United States Army as a Combat Infantry Dismount Team Leader with the 3rd Infantry Division and completed a 15-month deployment in Baghdad, Iraq, during 2007–2008. During that deployment, I was awarded the Combat Infantryman’s Badge, the Army Commendation Medal (2x), and the Army Achievement Medal. That chapter of my life shaped the way I lead, communicate, and perform under pressure.
Outside of work, I have been happily married to my wife Jess since 2022, and together we have two dogs, Lena and Hank. My Christian faith is fundamental to my day-to-day life and plays a fundamental role in how I carry myself, treat people, and lead with integrity. In both my personal life and my work, I strive to be dependable, steady, and committed to excellence in everything I do.

Patrick Bagwell: Design & Sales Consultant
From an early age, Patrick Bagwell had an appreciation for architecture and outdoor living spaces. For his high school senior project, he actually chose landscape architecture as the career to explore. After graduating with a degree in construction management, he first learned the intricacies of augmenting property value by flipping houses in his hometown, Augusta, Georgia. Though he enjoyed this position, it lacked the need for creativity and design he found so rewarding. He took a position with a custom pool builder where he took on the most complicated design requests. He went on to spearhead the company’s goal to be the go-to builder for outdoor kitchens and covered structures. These years proved valuable to help hone his craft of transforming a plain backyard into a fully functional oasis.
In 2015, Patrick came to visit one of his best friends who was then living in Austin; after only a few days, Patrick fell in love with the city and the beautiful Hill Country landscape. During his time designing in Austin, Patrick has won multiple APSP design awards and continues to explore cutting-edge build techniques to continually impress clients. Whether it’s designing free-flowing natural landscapes or straight-lined modern pools, he enjoys the challenge of designing spaces that fit the given landscape well while also keeping client’s respective budgets paramount.
When not creating beautiful designs, Patrick loves golf, is an avid fan of live music, and is a bit of a foodie.
