Mario Rosas

Mario began at Groves Electrical Service in 2006 as an Apprentice Electrician. After working in the field a couple years, he was transferred to the estimating department. Mario has applied his “in the field electrical knowledge” to the wealth of knowledge Charles has gained over his 30 years estimating to become a vital part of Groves’ estimating team. In 2015, Mario proudly received his Journeyman License. Mario loves the challenge bidding large jobs presents.

Mario has worked in the field on Great Wolf Lodge Waterpark, Schell Elementary School, Plano Rehab and Nursing Facility, Tom Muehlenbeck Center, and The Beat Condos. As an estimator, he was part of the estimating team that bid and was awarded such notable projects as SMU Tennis Center, HEB Auxiliary Building, Arbor Creek Middle School, SMU Ford Stadium Suites, Judy K. Miller Elementary School, Viridian Elementary School, James R. Newman Elementary School, Janice Stahly Scott Elementary School, J.L. Boren Elementary School, and Alice Ponder Elementary School.
