Thomas Keane, the head of the Boston Society of Architects, abruptly quit Friday, citing “important philosophical differences” about the organization’s goals and his role in pursuing them, a spokeswoman for the organization confirmed Wednesday.

“This was extremely disappointing news” to the board’s chairman, Lawrence Chan, said Karen Schwartzman, the spokeswoman.

Keane, an investor and former Boston city councilor, held the job for less than a year. He declined to comment for this article.

Despite Keane’s departure, a committee of the board continues to review a possible move to the new Russia Wharf project on Boston’s waterfront, Schwartzman said.

In a letter to members, the society’s board cited Keane’s “important contributions” during his short tenure.

The letter said there were differences “about the dynamics of leadership, independence, consultation and partnership related to the role of executive director.”

During a recent interview, Keane said increasing the society’s public exposure was a top priority.

“For years, the BSA has been talking about a more visible and public presence for itself,” Keane said in the February interview.
