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.

TJ Thompson: Vice President of Sales & Operations

As the son of Cascade’s founders, TJ Thompson has been at pool sites since before he could walk. Not surprisingly, he’s developed a strong sense of creativity and an eye for details, designing amazing pools and waterscapes for the last 15 years. Many of his designs have won international awards. He’s worked his way up from construction on job sites during college summers to project management, design, and sales. He currently oversees processes and operations and is very involved in the company’s overall strategic planning.

TJ was born and raised in Austin, TX, and attended Lake Travis schools from kindergarten to high school. TJ is a perpetual student of the pool industry. After attending college in Colorado, he brought 3D pool design to Cascade and is constantly studying the industry to learn the latest trends in construction and design. TJ is one of the few who holds a certification as an Associate from the Genesis school of Watershape Designers and has his certification through Water Shape University as a Verified Watershape Profesional. He is currently serving on the Central Texas chapter of Pool & Hot tub Alliance (PHTA) as one of its youngest acting members.

Theresa: Vice President of Finance & Administration

Theresa Thompson is the heart behind Cascade Custom Pools. She and Hank started the company in 1982 after graduating from Texas State with a degree in business. She’s been involved in many aspects of operations ever since, keeping things running smoothly for both employees and clients. Constructing pools requires a lot of moving parts, and she is a huge asset in keeping everything flowing with her people skills and business knowledge.

While raising their two sons, Theresa gained experience in other fields, including five years as an elementary teacher in Lake Travis ISD. She worked as a property manager for a commercial developer and continues to manage her own real estate investments. Even as she expanded her skill set, she oversaw the company’s finances, and as the company has grown, she has jumped back into the business fulltime.

Theresa loves being a part of a family business and growing something great together. When not helping with the pool company, she loves yoga, traveling, and spending time with friends and family.

He has built numerous award-winning pools for both international and national competitions while also having served as a judge for the 2014 APSP International Awards competition.

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.
