Trisha joined the Creative Tonic team in 2017 and her contagious smile is the perfect addition to every room. She feels blessed to work at a company that celebrates passion and finds great personal satisfaction doing what she loves in a creative place dedicated to bringing clients’ dreams to reality.

Born and raised in rural Wharton, Trisha is proud of her small town Texas roots. She is a graduate of Sam Houston State University, where she holds a BA in Interior Design.

Trisha developed a passion for interiors early on, building off artistic interests passed down from her father, a successful lighting designer. She studied design starting in high school before moving her interest more permanently into her college curriculum. Trisha further honed her skillset at Contour Interior Design in Houston during the latter half of college before her time at Creative Tonic.

Trisha’s positive outlook, attention to detail, and determination to please her clients are central components of her workflow, and Trisha’s work ethic is one of Creative Tonic’s biggest assets. She works to constantly weave the most current technology and up-to-date ideas into the Creative Tonic workspace. 

When Trisha is not at Creative Tonic, you can find her spending time with her fiancé, family and Dixie, her Australian Shepard.
