Mark has over fourteen years of experience in the museum sector, augmented with an MA in Museum Professions from Seton Hall University. He is passionate about the role of museums in our society and believes firmly that #MuseumsAreNotNeutral.

Since 2015, he has been on staff at the New-York Historical Society where he is the Registrar for Collections. He oversees new acquisitions, manages the Society's active outgoing loans program, organizes the registrarial logistics for travelling exhibitions, and collaborates on select in-house temporary exhibitions. Prior to that, he was on the registrarial team at the Solomon R. Guggenheim Museum.

From 2014 - 2017 Mark proudly served on the Board of Directors of ARCS (Association of Registrars and Collections Specialists) where he was also the Chairman of the Education Committee. In that role, he founded and managed the first fifteen editions of #ARCSchat, a monthly Twitter-based conversation on topics related to museums and collections management. You can now find this ongoing, lively, and relevant chat in its new iteration via the ARCS YouTube page.

In 2013, Mark founded @ITweetMuseums, a popular, non-affiliated, independent Twitter-based initiative which now has 15000+ followers. The account was created to encourage and support all cultural workers to tweet about museums from their personal accounts. For a look into museums from the point-of-view of the dedicated staff who work in them, seek out the hashtag #ITweetMuseums on Twitter, Instagram (where 15000+ photos have now been tagged), and other social media platforms. Or, check out these Wakelet posts of summaries from past events, chats, and university lectures, including various how-to resources.

Mark is also keenly interested in foreign languages. In addition to a BFA degree in Design, he has a BA in French, and is proficient in Castilian Spanish. He studied and worked in France and Spain for twelve years, and looks forward to any opportunity to travel abroad for either work or pleasure.
