Detroit, MI -- Spalding DeDecker Associates, Inc. (SDA) acquired Dietrich, Bailey and Associates, PC (DBA) on Wednesday, February 4, 2009.

Both firms are Professional Engineering and Surveying firms who have served Southeast Michigan for many years. DBA is headquartered in the City of Plymouth with a second office in Monroe while SDA is headquartered in the City of Detroit with additional offices in Rochester Hills, Brighton, and Trenton.

SDA President, David Lakin, PE said, “The combination of SDA and DBA will make both companies stronger.

DBA will continue to serve their client base out of their Plymouth and Monroe offices, and Michael Bailey, PE will remain in his current capacity as President in charge of DBA. “We are very excited to join forces with a strong company like SDA while providing an ownership stake for me and DBA’s employees. This bodes very well for the future of DBA, our clients, and our employees,” said Michael Bailey.
