Our Board

Message From Our President

Dear PEMA Supporters:

We appreciate your support and welcome your ideas and continued involvement.  PEMA seeks to involve all in the professional environmental community, from owners to regulators to consultants, contractors, and vendors for the purposes of networking, educating, informing, and sharing business opportunity information. PEMA became an even more important connector in the virtual environment we found ourselves in 2020 and 2021. In 2022, we look to return to more in person events that we have all missed these past two years. We continue to grow as an association by numbers and knowledge, and are now more diverse than ever. This diversity is instrumental to an organization serving the environmental industry, which intersects almost every industry, profession, and person in some way … and PEMA strives to connect these dots. ​In 2022, our goal is to build upon the success of the past and position our members, and the community in which we serve, for continued success in the future.  With your support we can reach this goal – educating, connecting, and giving back to the community more than ever before.  Our aim is to continue to increase our footprint and membership, develop new and relevant speaking programs at our monthly meetings, and continue to create an environment that creates value to our members, guests, and our speaker organizations, as well as the charities and educational programs that we financially support.​ On behalf of the PEMA Board of Directors, we are excited for the opportunity to serve our members in 2022, and I am honored to be leading the way as your President.
