skate to where the puck is going;
nurture familiarity by prioritizing trust and respect;
engage in provocative and inspiring dialogue;
seek out diversity of thought;
and create a safe place to explore new ideas and initiatives

What our members say

“What I love most about the GDA are the personal relationships. I’ve had the opportunity to develop with inspiring practice leaders from across North America. I learn something new whenever we come together. And whenever I need advice, I know that I can pick up the phone or send out a quick note, and within the hour I’ll have the benefit of their friendly, practical wisdom. Extremely rewarding, both personally and professionally!”

– Jeff DiBattista, DIALOG

“Alliiance has been a long-term member of the GDA. Throughout the years, our firm has formed strategic partnerships and we have benefitted from many collaborations with other GDA member firms – and I personally have gained many deep friendships. We constantly have been able to access a deep bench of experience in all practice areas because of the diversity of members within the GDA. Even more so, I have had shoulders to lean on and people to look to for advice during these uncertain times.”

– Tom Hysell, Alliiance

“I am fascinated and enriched by all of the different ways that the companies within the GDA have chosen to organize themselves. While addressing the same big-picture industry issues, we are each working in a different organizational model. That combination of similarity and diversity enables us to have both well-informed and changeful conversations, tackling topics such as leadership, diversity and inclusion, structure, succession planning and culture in unique ways.”

– Melissa Marsh, Plastarc
