Top 100 firm Kahn, Litwin, Renza & Co. Ltd., has agreed to merge with Fay & Associates.

“The merger provides us with the opportunity to continue to deliver the outstanding client service and personal attention that our clients deserve and expect from us, but with more resources and a wider array of services” Fay & Associates partner Stephen Fay said in a statement. “We are pleased to find that our firms share the same values and vision of quality and excellent client service.”

The newly conjoined firm will operate as KLR. Fay & Associates has already relocated to KLR’s Waltham office. The pairing will boost KLR’s staff to 170 professionals.

“We are excited about Steve and his team joining KLR and welcome all of the Fay & Associates’ clients, friends and colleagues to the KLR family,” KLR managing director Alan Litwin added. “The merger expands our footprint and impact in the New England marketplace and adds a very talented group of professionals to KLR.”
