Family owned and operated for 53 years

Tucson and Green Valley

Casa Blanca Exxon was founded by Rex & Lenora McKenzie, parents of Cheryl McKenzie Cox. Rex started in the service station business on Tucson's south side in 1956.

Bill Cox was right out of high school when he started working for Rex. Shortly after Bill & Cheryl's marriage in 1962, Rex and Lenora purchased a second Exxon station - Casa Blanca Exxon at Oracle and Rudasil. Bill operated the south side location and Rex and Lenora moved to the north side location. The south side locations was sold in 1968 when Bill left to pursue another career in the tire business.

In 1977 Rex McKenzie suffered a stroke and Bill Cox returned to help with the business. Within five years, Bill had increased the business to numbers that persuaded Exxon, USA to rebuild the Casa Blanca site. Exxon also encouraged him to purchase a second site in Green Valley. This being Green Valley Exxon, established in December 1984.

Coxco's growth from this point is attributed to many years of hard work, long hours, and dedication by every member of the family. Corey Cox, son and DeVon Bronson, daughter, started in the business during their high school and college years, doing everything and anything that had to be done. Joe Picchioni, nephew in law, started training at Casa Blanca Exxon in June 1984 and moved to manage the first Green Valley location (Esperanza Exxon) when it opened in December 1984. Louisa Cox, daughter-in-law, started with the company at Casa Blanca Exxon in February 987 prior to her marriage to Corey. Scott Bronson, Son-in-law, started at a C-store location in February 1990. He moved to the Super Center location when it opened in August 1991 and has been building the Coxco C-mart business ever since.

This family business has developed and grown year by year to become the COXCO of today. Bill and Cheryl attribute this growth to one thing....The total involvement of the entire family over the years to do whatever it takes "to get the job done right".

Coxco today consists of 3 locations that include Premimum Gasoline, Convenience Stores and now Dairy Queen at our Casa Blanca store . The "mom & pop" service station of yesterday has become Coxco Corporation of today with that same "mom & pop" feel.
