Local Allstate Agent: Meet Deirdre Erin Cosgrove

I have been an Allstate agent in the White Plains, NY community since 1996. The best way that I can explain White Plains is a mini Manhattan tucked in the suburbs of Westchester. My favorite places to go in town is Francesca’s Restaurant and Lola’s.

My family consists of my husband, Tim Fay, who is also an Allstate Agent in Rockland County. We have 2 sons, Timmy and Chris, and 1 daughter, Michaela. All of our children are involved in sports within our community in Suffern, NY. They play football, lacrosse, baseball, basketball, wrestling, and soccer. I come from an Allstate family, my father was an Allstate Agent for over 25 years. I have 2 brothers that are both Allstate agents.

I am very involved with charities and non-for profit organizations such as PTA, the Ladies Ancient Order of Hibernians, President of the Suffern Girls Youth Lacrosse, and I help coach our local girls youth lacrosse teams. I support Loyola College Athletics, Sacred Heart Church, Sisters of Life, Purple Purse, JDRF, Autism Speaks, Viola Elementary School and local Fire and Police Departments. Some activities that I enjoy are running, going to the beach, and spending time with family and friends.

I became an Allstate agent because I enjoy working with people and helping them to properly protect themselves, their families, and their assets. My office is located near the intersection of Mamaroneck Ave and Old Mamaroneck Rd, across from Italian Pavilion Pizzeria. Stop in today and get a quick quote. You can also email or call us if you are in a hurry.
