Leadership
Sean McElwrath - Founder
Sean McElwrath is the Founder and Managing Principal at Bedrock Supply, overseeing all vendor and customer relationships, sales, and company operations.
After graduating from the University of Texas in 2007, Sean cut his teeth in the oil & gas business working for E&P operators based in Houston and Austin, Texas. Switching gears in 2019, Sean jumped at the opportunity to launch the Central Texas branch of a construction materials supplier with a decade worth of experience servicing concrete subs and self-performing general contractors. Over his five years with the company, Sean grew the customer base to include concrete subs, GCs, and developers across the residential, commercial, and public infrastructure space, providing material solutions for projects in all the major Texas markets. In late 2023, Sean got the itch to start something of his own headquartered in Central Texas, taking the lessons he’d learned with the company to start Bedrock Supply.
Outside of the office, Sean spends most of his time chasing his 3 children Tommy, Jack, and Amy around Austin with his wife, Sarah. They are avid supporters of UT Athletics and members of Covenant Presbyterian Church.
Bryan Gilliland - Operations Manager
Bryan Gilliland is the Operations Manager at Bedrock Supply, overseeing all aspects of logistics, inventory management, and warehouse management.
While completing his studies at Alabama and Texas A&M, Bryan worked earnestly to gain hands-on experience in the construction industry. He started in the field as an installer for a commercial glass fabricator and then as a custom home building superintendent for Sitterle Homes.
Having grown up in East Texas, Bryan feels most at home in the great outdoors. He enjoys fishing and hunting all over Texas with his puppy, Maya. In his spare time, you can find Bryan hiking some of Austin’s beautiful trails, playing guitar downtown, or sparring at a local boxing gym.
