Koleas Family founded Western Emulsions
Richard and Ramah Koleas began the Koleas asphalt legacy by establishing Western Emulsions in 1977 in Tucson, Arizona. The company started as a small player in the industry, competing against large corporations, but Western Emulsions found its niche with an emphasis on branded, specialty products and superior customer service.
Western Emulsions builds its Irwindale plant to distribute GuardTop.
Richard Koleas worked on the original formulation for GuardTop sealcoat by incorporating Western Emulsion asphalt emulsion.
Bob Koleas begins in the industry.
Robert Koleas, current CEO of GuardTop and son to Richard and Ramah, grew up in the industry.  Bob worked on seal coating crews in the summers as a kid and while in college, he designed and oversaw the building of the Irwindale plant. After graduating from the University of Arizona in 1987, he was appointed Sales Manager of Southern California.
Early 2000s
Bob Koleas named Vice President and CEO of Western Emulsions
GuardTop is acquired by Western Emulsions.
Koleas recognized that GuardTop was still the best product in the industry and was thrilled at the opportunity. After assuring the board of the company’s incredible potential, Western Emulsions acquired GuardTop in 2009.  Western Emulsions, in partnership with Advantage, was able to transform GuardTop through continual product improvement, brand protection and exceptional customer service.

Koleas was approached by Vulcan Materials Company to purchase the GuardTop division. Vulcan chose to only approach Robert and Western Emulsions. Due to Vulcan’s long-term working relationship with the Koleas Family, the company knew Robert’s team would take care of the existing GuardTop and Vulcan materials customers.

Bob Koleas inducted into the Asphalt Emulsion Manufacturers Association Hall of Fame.

Mr. Koleas received recognition for his experience overseeing the modern growth of Western Emulsions from a small family-operated emulsion plant to a regional enterprise with nearly 100 employees and manufacturing facilities in seven US states serving customers in 21 states. He led the branding and development of a line of innovative rejuvenating asphalt products providing roadways with greater longevity, with a focus on environmental responsibility.   Mr. Koleas also dedicated years of service as a member of AEMA’S Board of Directors.
