Management Team

Mariner founders Peggy and Peter bring a combined 50 years of experience working with associations to Mariner Management & Marketing. They also brought 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.  

PeggyPeggy M. Hoffman 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 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 and is past chair for their Component Relations Section Council and currently serving on the Executive Management Council. She served on the development team for the Principles of Components Relations web-based course and wrote a chapter in the Components Relations Handbook: Tools & Tips for the Component Relations Professional. She was also involved in ASAE & The Center’s groundbreaking Decision to Volunteer research project. Peggy was part of the team that helped develop ASAE’s communications certificate program in the early 90’s and taught two of the segments.

She has been a writer and speaker for ASAE & The Center and various other organizations. 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. If Peggy wasn’t here, it’s very likely she’d be out training for her next triathlon.

PeterPeter 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 18 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. He also serves on the AAE Technical Section Council. 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.
