Board of Directors

League Officers and Directors

President  Alice Duffee


Trained as an architectural historian and historic preservation planner, Alice specializes in evaluation, recordation and inventory of historic resources, and provides consulting services through her company, APD Preservation, to satisfy cultural resource compliance requirements at the federal, state and local levels. Architects, contractors, and home owners retain her when they have a vision for their property and can't wait months or years of trying to navigate the complex business of city planning and environmental compliance.

Vice President Martin Laney

Having been raised in Sonoma, and lived in the valley most of his life, Martin’s involvement with the League for Historic Preservation is a natural extension of his appreciation for the opportunity to live in a wonderful location with such an important historic heritage. It’s not an overstatement to say that Sonoma is the birthplace of modern California, and as such, occupies a unique position, spiritually and physically, in the history of our state. Martin’s thinking aligns closely with the League’s purpose of preserving, protecting, and promoting that history, along with educating residents and visitors about the importance and impact of what has transpired here in our valley, and where our history actually took place. Being a recent retiree from the  telecommunications industry, he looks forward to being able to devote some of his new found time to helping the League further advance and expand upon that mission.

Director Michael Hospelt

I remember that I always had a camera. My father, who documented World War II, taught me how to photograph when I was still a child. Winning First Prize in a youth photography competition when I was twelve steeled my resolve to become a photographer.  After I finished school I had the opportunity to apprentice as the assistant to the well-known architecture photographer Hans Schafgans in Bonn Germany. This technically challenging education threw open the doors of the elite art school Folkwangschule in Essen for me, where for six years I honed my visual horizons by studying photography and design.

During the ensuing years I traveled the world as fashion and advertising photographer, my clients encompassing international magazines and ad agencies.  Directing commercials and documentaries lent itself as a natural progression, which led to my work with the renowned Filmhaus production company, where our advertising clients included such international brands as Volkswagen, Beck’s Beer, Sony, Philip Morris and many others. 

Anticipating the emerging internet media platform, I later founded NEWTECMEDIA with two partners.  I served as its CEO in Hamburg, Germany until 2001, when I moved to the United States. After having put my camera down so many years ago, I slowly begun to enjoy my old love photography again. First photographing Landscapes, and then, in 2015 through introduction, I begun photographing architectural exteriors and interiors for professionals in the building industry, coming full circle.

Director Nina Small

The fascination with architectural design at a very early age led Nina to pursue a degree in art from West Chester University in Pennsylvania and subsequently a successful career, not as an architect but as an art director. She worked with many high profile companies and clients in the healthcare, automotive, retail, financial, tech and pharmaceutical sectors. She has also served as a Human Resources professional for Nason Construction, a design build firm on the east coast. She holds two professional certifications in Human Resources and is currently on the board of the Northern California  Human Resources Association representing the North Bay Region. Formerly she served on the Arts Guild of Sonoma board and has been an active volunteer in many of the non-profit outreach programs to advance art programs in Sonoma Valley. Currently she is working in customer relations at the corporate offices of Restoration Hardware.

Director Susan Staggs

A native Californian, Susan received a BA in English and an MA in Management and Organization Development. She had a career in Human Resources Management at various high-tech companies in Silicon Valley before retiring in 2000. She and her husband, Havard, then moved to the Sierra Foothills during which time Susan became active as a community volunteer. She was a member of the Sutter-Amador Hospital Foundation Board and the Amador County Mental Health Board, President of the Friends of the Amador County Library, the Amador Branch of the American Association of University Women, and the Sutter Creek Woman’s Club.

After moving to Sonoma in 2015, she served for 3 years on the board of Sonoma Valley Newcomers Club and currently serves on the Grants Committee for Impact100 Sonoma. For the past couple of years she has also served as the Docent Coordinator for the League’s Maysonnave House.
