The company is using only about 25 percent of its total Amherst office space so far and plans to expand in phases, Sasson said. Next year, it will renovate another 40 percent of the space and move into it by the end of 2018.

Strategic Financial is a new player in the local financial services sector, which has been one of the most robust parts of the Buffalo Niagara economy during the recovery, as banks and insurers sought to take advantage of lower pay scales here compared with major financial centers, like New York City.

Since the end of 2014, the region's financial activities sector, which spans banking and insurance and real estate, has grown by 5 percent, which is more than double the pace of hiring across Erie and Niagara counties during that time.

Because financial services jobs tend to pay about a third more than the average local job, the overall economic impact of the financial sector also has outpaced the local economy, rising by an average of about 4 percent a year between 2013 and 2016, compared with 1 percent annually for the entire region.

Jordan A. Levy, a local investor in Strategic Financial Solutions who helped persuade Sasson to expand the company here, said he is eager to see the office space get filled up. He likes the results so far.
