Six former attorneys from Seiden & Schein P.C., a real estate boutique law firm, have joined the commercial real estate law firm Adler & Stachenfeld LLP: named and founding partner Alvin Schein, Hillary A. Potashnick and Stacy E. Jacobson, as well as three associates and members of the Seiden & Schein professional team.
“This is an exciting time at Adler & Stachenfeld,” said Managing Partner Terri Adler. “Alvin, Hillary and Stacy are natural fits for A&S and are joining us at a time of significant growth. The additions to our NYC Real Estate Tax & Zoning Incentives Practice Group, and the creation of a Condominium & Cooperative Practice Group, will amplify our ability to serve our developer, owner and lender clients in guiding them through the ever-changing and highly complex landscape of New York City real estate and policies.”
“Adler & Stachenfeld’s sole focus on real estate and deep bench of expertise are the perfect fit for my background and the team of talented professionals that have joined me in this perfectly timed move,” Schein said. “This will enable us to continue to meet the growing demands of our high-profile developer clients.”
A recognized expert in cooperative, condominium and affordable housing law. Schein will co-chair the NYC Real Estate Tax & Zoning Incentives Practice Group with YuhTyng “Tyng” Patka, a partner at Adler & Stachenfeld who has chaired the practice since 2019. He has spearheaded the filing of more than 200 inclusionary housing plans with the NYC Department of Housing Preservation and Development and is one of the few attorneys in New York whose practice includes the representation of sellers and purchasers of inclusionary air rights.
Potashnick will chair the firm’s new Condominium & Cooperative Practice Group. The practice will represent developers of condominiums and cooperatives — including market-rate, income-restricted, and mixed-use projects — across New York City. Potashnick has more than 30 years of experience in acquisitions and sales of real estate; cooperative/condominium new construction and conversion projects; all aspects of registrations and representation of developers, lenders and co-op and condo boards; financing and workouts between purchasers and developers/lenders; advocacy before the New York State Attorney General’s office and general real estate practice.
Jacobson has joined as a partner and will focus her practice on a broad array of real estate transactions, financing, leasing and development matters, as well as practicing in inclusionary housing. With almost 25 years of experience, Jacobson counsels her clients on the acquisition, financing, leasing, development and disposition of real estate and real estate-related assets of all property types.
Associate David W. Lu will work with Potashnick in the Condominium & Cooperative Practice Group, and Associates Scott A. Schreiber and Efram Klipper will work with Patka and Schein in the Real Estate Tax & Zoning Incentives Practice Group.
