Ascent Building Services

About Us

Ascent Building Services Group, LLC. was born from the same desire that led its founder, Dean Siegel, to climb mountains — the adventure, challenge, pursuit, and push for the summit. The lesson he learned from summiting Mt. Rainier in Washington was that the biggest mountains are not to be climbed alone. Preparing and implementing a strategy to safely and successfully reach the summit and get back down takes a team effort with each member contributing their best effort. The reward of a shared struggle and success is much greater than that from singular accomplishment. is a full-service commercial janitorial provider that is based in North Texas.
