Mariner Management & Marketing LLC

Management Team

Mariner founders Peggy and Peter bring a combined 60 years of experience working with associations to Mariner Management & Marketing. They also bring a cadre of experienced professionals who round out the team as needed to provide the best service to our clients.

Our bios will provide a little background on our key team … but we’d much prefer to talk to you so give us a call to learn more.  

Peggy M. Hoffman, CAE, is president and Mariner’s resident expert on communication, marketing and building community. In addition to managing organizations, Peggy has provided training and consultation on leadership development, component relations and strategic planning to more than a dozen national associations and many local groups over the past 30 years.

From her earlier role as membership director for a trade association with components, Peggy developed a commitment to building strong communities within associations. To that end, she has been very involved in ASAE - The Center for Association Leadership and is past chair for both the Component Relations Section Council and the Executive Management Council. A key project of the council is the “Rebuilding the Volunteer Spirit”, one of ASAE’s inaugural Innovation Projects. The intent is to explore how associations can adapt to and build on the changing volunteer and develop tools and strategies that can be a catalyst for rethinking our governance and member engagement models.

She also served on the Decision To Volunteer taskforce, development teams for ASAE University’s On-Line “Principals of Component Relations” and “Advanced Component Relations” courses, and the inaugural ASAE Foundation Development Committee. She has written for ASAE publications, including a chapter in the 2012 ASAE Components Handbook, and been a frequent content leader.

Peggy loves to write and share, so you’ll find her contributing to a variety of organizations and media including Association Universe. She has presented workshops or keynotes for more than 40 volunteer leadership conferences, retreats, and webinars ranging in size from 30 to 300 participants. With Peter, she has developed and taught several volunteer management courses for the Nonprofit Leadership Development Program at Anne Arundel Community College.

In addition to a BA in Communications from The American University, Peggy is a graduate of the association management curriculum of the Institute for Organization Management at Notre Dame and has worked in the nonprofit arena for more than 30 years. She has held positions in membership, marketing and communications for several different profession and trade associations prior to starting Mariner.

If Peggy wasn’t here, it’s very likely she’d be out training for her next triathlon.

Peter Houstle is CEO/COO and the in-house expert on meetings, financial management, and strategic planning. Helping associations navigate the intricacies of effective financial planning and program development comes naturally to Peter after 30 years in association management and 10 years working behind the scenes — and on stage — in the entertainment industry. He served as executive vice president for an international trade association and industry foundation, in addition to assisting dozens of other associations.

Whether it’s a 10,000+ attendee/1,000+ booth trade show in Chicago’s McCormick Place, launching a career marketing program, building a solid membership base or putting in place secure financial management systems, he handles the details without losing sight of the big picture.

Peter has been a speaker and writer for ASAE - The Center for Association Leadership. He served on the ASAE Technical Section Council and continues to be an active ad-hoc volunteer. With Peggy, he has developed and taught several volunteer management courses for the Nonprofit Leadership Development Program at Anne Arundel Community College.

Peter earned his MBA from University of Maryland’s Robert Smith School of Business and a B.A. in Music from Ithaca College. And when he’s not helping associations achieve goals, he’s likely in the heat of a pick-up basketball game or relaxing at the piano.
