What People Are Saying About Us

"I was thrilled to hear about the merger of The Levy Partnership and MaGrann Associates. We have had the privilege of working with both organizations and it is easy to see the synergies between them. This is clearly a case where the whole will be greater than the sum of its parts.”

- Mitchell Forlenza, Senior Vice President – Construction, AvalonBay Communities, Inc.

“We couldn’t have done it without [MaGrann]. LEED Version 4 Platinum certification enables us to enhance the marketability of each unit and therefore lowers the utility cost. It’s been a great experience”.

– Joel Wallace, RPM Development Group 

“Working on the project with MaGrann Associates was a sheer pleasure. They were very knowledgeable about their fields and quick to form solutions when issues arose.”

– Allen Cowling, Torti Gallas
