The executive director of the Oceanside Museum of Art has resigned as the organization embarks on a new phase of “rapid organizational growth,” the museum announced May 26.

The museum’s board of trustees has named Development Officer Sandra Chanis, a longtime museum supporter, as interim executive director in the wake of Daniel Foster’s resignation, according to the museum’s announcement. Foster has been the executive director since 2012.

“I am very proud of the tremendous, growth, accomplishments and partnerships that we have experienced at OMA during my tenure,” Foster said in the museum’s announcement. “Oceanside has a special place in my heart and I will miss working with our talented staff, board, supporters and partners.”

Museum officials lauded the museum’s growth during Foster’s time as executive director. Under his leadership, the Oceanside museum saw revenue double and membership increase by 35 percent, the announcement stated.

“Daniel is a visionary leader who has elevated our museum to a new level of recognition, professionalism and prosperity,” board President Robert Pendleton said in the announcement. “Under his guidance the quality of exhibition programing has risen to new heights, engagement of community patrons and artists has been enhanced in new and imaginative ways, and strategic planning has occurred that perfectly positions the museum for continued growth and development.”

Chanis will serve as interim executive director while the museum conducts a nationwide search for Foster’s replacement. Chanis is a longtime leader and volunteer at OMA. She formerly served as OMA board president and as co-chairwoman of a capital campaign, according to the museum.

“I am deeply honored to be chosen to lead the foundation during this time of transition and change,” Chanis said in the announcement. “While Daniel will be missed, we want to wish him all the best as he enters a new stage in his life and career.”
