SLP began in 2005 as an application of the myriad experiences, skills and knowledge of its founder, Sheri L. Pasquarella. As the organization expands, we collaborate with individuals that extend their own expertise and talents to our practice and clients. Below are some of the people essential to our success.


Sheri L. Pasquarella (Owner & Director)

Sheri began her professional career in leadership positions at two contemporary art galleries: Marlborough Gallery, New York (1998-2002, Associate Director of Admin) and Gorney Bravin + Lee, New York (2002-2005, Director). In 2002, she conceived and co-founded the New Art Dealers Alliance (NADA), a 501 c-6 organization that spawned a popular, successful art fair. In 2003, she became the Curator/ Advisor of the Stanley & Nancy Singer Collection; since that time, she has built or contributed to a more than 10 important private collections of art. Due in large part to NADA’s success, in 2005 she received the Future Visionaries Award from ArtTable and was named among the “most influential in art” by New York magazine. The public launch of SLP in 2006 began with the development of the West 27th Street galleries, a real estate project that she spearheaded. Since 2007 she has been teaching & researching and in 2008 she became the founding Arts Editor of Tar Magazine; for more details on these and her other public or educational activities, please visit our Community page. Sheri received her BA (and M.A. course work) in Art History & Criticism from SUNY Stony Brook, and did post-bac work at Reid Hall, Paris in social sciences & architecture.
