TMHS Senior Parent Organization (SPO) is a non-profit educational organization serving Tomball Memorial High School. Our primary purpose is to plan and prepare for Project Prom. Our goal is to provide a safe and fun place for TMHS students to go after Prom free of alcohol and drugs, and also to provide many fun activities for their senior year. This is done by 1) raising funds and obtaining donations from individuals, business groups, corporations, foundations and other donors in the community, and 2) using the funds to provide prizes, games, entertainment, decorations and food for the numerous events for our high school seniors including Project Prom.
At Project Prom Seniors can win amazing raffle prizes such as dorm refrigerators, microwaves, virtual reality system, gaming consoles, etc. The more raffle tickets your student has the better their chances to win. There will be several opportunities for you to earn raffle tickets for your student by volunteering or donating items as the year goes on.

Membership Levels:
There are three SPO membership levels which include different benefits. After you have chosen a level, please fill out your contact information, shirt size, etc. and click "Add To Cart" to initiate payment.
