MBCO/OEI a Partnership


Who We Are

OEI, Oller Engineering, Inc., was formed in 1989 in Lubbock, Texas by Rich Oller to serve the municipal clients in west Texas and the Panhandle; cities, counties and townships from small to large communities.  OEI’s professional services include the full gamut from infrastructure development and water systems improvements to engineering design for roadways and highways, and environmental services including Phase I EA’s to remediation of Brownfield sites.

While the Texas and engineering communities already know and respect OEI’s reputation, it is the years of hands-on experience that Rich Oller brings as an operator in water and wastewater treatment plants; an advantage that few, if any, other engineering firms can offer. Not only does he understand the operations of these facilities, he can design them for the utmost operational efficiency. OEI brings that old-fashioned “boots on the ground” approach to solve the problem and stays beyond to assure the systems work as designed.

OEI serves as a mentor to MBCO Engineering, a woman-owned civil engineering firm in Houston. “We are more than mentors, we are partners with this young firm. We will teach by example and promise to focus on what is really important to the people we work for—to create reasonable solutions and meet their needs first.”
