Chuck Wemple
Executive Director
Since its inception in 1966, the Houston-Galveston Area Council has grown into one of the largest, most expansive councils of government in the country. This kind of success is not possible without the exceptional talent, dedication, and passion of its people. Our leadership team reflects who we are as an agency. They are diverse, talented, flexible, collaborative, engaged, passionate, and most importantly, they are extremely dedicated to the success and development of their teams and to the vitality of the 7 million people living and working in this great 13-county region we serve.
However, what most impresses me about our leadership is how approachable they are to discussion, ideas, and opportunities to learn and improve. Their integrity, humanity, and humility are apparent in all they do. They invest in their people. They want everyone to succeed.
I encourage all members of our staff to reach out to a member of our leadership team, start a conversation, and make a connection. You may be seeking training and professional development. You may need advice or help with a project. You may be new to our agency and need a guide. You may aspire to be a leader yourself and need a coach. You may have an idea to improve a process, expand a program, or reach a community we’ve overlooked in the past. You may simply want to know more about a department you don’t regularly work with. We want to talk about it. Our door is always open, and we are always willing to listen.
Thank you to all our staff for your engagement and dedication to our mission, the region we serve, and to each other. We are your leadership team. We’re here for you, and we’re here to help.
