Bio coming soon.


Board Member - Angela M. Maiorano

I am a McKinley County resident, living in Gallup for over 20 years. My husband and I raised 5 children here, who have given us three beautiful grandchildren so far. My husband is a career law enforcement officer who has served McKinley County residents for the last 23 years. I have worked short term jobs and volunteered for nonprofits throughout my child-rearing days, all of which were in the areas of public works, public safety and service to my community. All our children are grown now and have moved away so I have decided to increase my activity within our local communities. I enjoy researching McKinley County history with my most recent project being the research of those laid to rest in the now abandoned Hillside Cemetery on Gallup’s northside.
