Insero & Co. has acquired Rochester, N.Y.-based Marquise Business Solutions LLC. The acquisition is part of the firm’s initiative to expand its Small Business practice.

Marquise, which was founded in 2007, specializes in accounting, finance and strategic business consulting for startups and small to medium-sized businesses.

Paul LeFrois, who is the former managing member of Marquise, will continue to provide these services as part of Insero’s Small Business Group.

“We have worked with Paul in the past and are very pleased that Marquise Business Solutions is now an integral part of our team,” Insero managing partner Nancy Catarisano said in a statement. “We are continuing our major push in small business because we believe small business is still a growth area in Rochester.”
