SCOTTSDALE, Ariz., November 3, 2023 –
On Oct. 26 (Tucson) and Oct. 28 (Phoenix), the Cystic Fibrosis Foundation, Arizona Chapter, honored Ross and Patty McCallister, owners of MC Companies at their annual gala events, [raising $459,000 towards CF efforts] with the prestigious “Breath of Life” award for their philanthropy and support of Cystic Fibrosis. They have been two of the biggest supporters and champions of Cystic Fibrosis in Arizona.
Ross and Patty grew up in New Mexico on opposite sides of the state. They met in 1971 as college
freshmen at New Mexico State University. They were married in 1974 and have two daughters,
Amanda and Anna. Their family of four moved to Tucson, AZ, in 1983. Together, they created The
McCallister Company, a real estate development and management firm owning and managing
multifamily investments across Southern Arizona. Being very active parents, they continuously
volunteered at school events, sporting events, Girl Scout meetings, and church. In 2001, they merged
their business with partner Ken McElroy to create MC Companies. Ross and Ken have expanded the
business to three states and nine cities, managing 7,500 apartment units and employing over 280
As their family grew, Patty and Ross welcomed Amanda’s husband Tom and their son Mac, and
Anna’s husband Kevin and their daughters Jolene and Cecilia. In 2007, at six months old, Jolene was
diagnosed with cystic fibrosis, and in 2012, Cecilia was diagnosed at birth. With this diagnosis, Patty
and Ross focused their fundraising goals towards the Cystic Fibrosis Foundation, a disease they had
never heard of until Jolene’s diagnosis.
As the business grew, so did their efforts in community service. One of MC Companies’ Core Values is
“Be Giving.” The MC Companies “Sharing the Good Life Foundation” was created to further that Core
Value. Together with their partners and employees, they have volunteered thousands of hours and
raised over $1 million towards finding a cure for Cystic Fibrosis. Blessed with giving hearts, Patty and
Ross also fundraise for Autism Awareness, New Mexico State University First Time College Student
Scholarships, University of Arizona College of Nursing Scholarships, and various local and regional
The Cystic Fibrosis Foundation works to cure cystic fibrosis and provide all those diagnosed with CF the opportunity to lead long and fulfilling lives by funding research and drug development,
partnering with the CF community, and advancing high-quality care.
“Though they may not actively seek publicity, their remarkable impact on our work in Arizona and
across the country has not gone unnoticed, leading the community to earnestly request a celebration
of their achievements,” said Charles Colmark, Area Director for the Cystic Fibrosis Foundation, on
recognizing The McCallisters.
