Cornerstone Earth Group, Inc. had such a wonderful time at David J. Powers & Associates, Inc. 50th Anniversary Party, which took place in September on the rooftop of The Tech Interactive Museum in downtown San Jose. David J. Powers was one of Cornerstone’s first clients, and it was a pleasure celebrating not only with their staff, but with staff from many other local cities and professional firms that we have worked with on so many high-profile projects. We look forward to all that is to come during the next 50 years. Cheers!
