Alexandra 'Sasha' Suda, who has had a decades-long career as an art historian and curator, was hit with the news Tuesday morning, Philadelphia Magazine reported.

Suda, 45, was told via email that she was being fired for 'cause'. The museum board also wished her 'every success' in her future endeavors.

In a statement to the Daily Mail, the museum confirmed Suda's departure, adding that Louis Marchesano, deputy director of curatorial affairs and conservation, will lead day-to-day operations until the board appoints a new chief executive.

The museum did not offer a reason for the firing, referring to it as an 'internal matter'. Suda could not be reached for comment. 

She spent three years as the museum's leader, arriving in 2022 and immediately shaking things up.

Suda released an equity agenda shortly upon arrival that included goals such as 40 percent of employees from diverse backgrounds by 2025, 35 percent supplier diversity by 2025 and $5 million raised for African American art by 2025.

Suda has said these goals, all of which were reportedly achieved this year, were discussed behind the scenes before her tenure began. 

'It's new in that we're having the confidence to express it outwardly, but that intention was there all along,' she told WHYY-FM, a Philadelphia public radio station, in 2023.

That year, she established the Brind Center for African and African Diaspora Art, a permanent wing of the museum that was 'dedicated to the study, acquisition, and care of art from continental Africa and the African diaspora.'

This year, Suda introduced The Time is Always Now - a limited-time exhibition that showed off paintings, sculptures and drawings made by 28 contemporary black and African artists.

Suda was also a key player in securing an exhibit called the Nation of Artists featuring artworks from Philadelphia Phillies owner John S Middleton. His and wife Leigh's collection is considered one of the best in the world.

However, Suda has been on the receiving end of criticism in the last few weeks for her decision to rebrand the Philadelphia Museum of Art as the Philadelphia Art Museum.
