Roberto grew up in the Church of Jesus Christ of Latter-Day Saints. He graduated from South Mountain High School in 1973 and attended Phoenix College and Northern Arizona University in Flagstaff, AZ.
In 1981, he started his career working with the state Medicaid program. Through this work he recognized the needs of Phoenix’s vulnerable populations and decided he needed to do more to help. This led to work in county and city government programs as an advocate for the homeless, elderly and mentally challenged. In 1995, he began his long and successful career with the City of Phoenix. He was dedicated to improving the physical aspects of neighborhoods and improving the quality of life for residents. He worked tirelessly with community advocates in the Garfield and Maryvale communities and was passionate about advocating for the needs of all individuals who wanted change in their neighborhoods and safe living conditions. He received multiple awards throughout his career for his dedication and was loved by many colleagues and community members.
While working at the City of Phoenix, Roberto met his second wife, Maria. They dated for many years and married in 2020 during the pandemic. She supported Roberto throughout his long battle with cancer.
Roberto was an avid reader, enjoyed hunting, listening to music, spending time in northern Arizona and watching sports (Go Raiders!). He loved being a dad and grandfather.
Forever in our hearts, rest in peace.
