Over 400 people, mostly employees, were at the big 100th anniversary celebration.
Company and community leaders say hitting this century mark shows economic stability and pride for the Mohawk Valley.
"One of the largest contributors to this community financially, millions of dollars over the years, it's a wonderful day and I hope they're here another 100 years,” said New York State Senator Richard Hanna.
Congressman Richard Hanna was among the hundreds of people that came out for the 100th anniversary celebration of Utica national. His excitement for the local group's milestone was shared by all.
"To have their presence here in this community, to keep people working and to contribute so much in so many ways is a great way for us to recognize 100 years," said New York State Senator Joseph Griffo.
"100 years in this community and they played such an important role in some of the major disaster that we experienced here in New York," said Roan Destito of the New York State office of general services.
Company leaders say the company has evolved tremendously over the 100 years.
"We started out as a very small worker's compensation company in Utica and now we're licensed in 50 states and Puerto Rico and we're one of the top 100 insurance companies in the United States," said Utica National CEO J. Douglas Robinson.
Throughout the evolution one thing has remained constant, their home base.
"There's a wonderful workforce here there's a work ethic here that's hard to repeat anywhere else in the united states and we have offices all over the United States but this is still home," said J. Douglas Robinson.
"We're real excited here this is just really affirmation that the Mohawk Valley and central New York is a great place to live, work and do business," said Utica National President Richard Creedon.
The company also made a big announcement tonight.
They donated one million dollars to the community foundation to look at root-cause issues in the area.
