Who We Are

Lea Emery

Managing Partner


Ms. Emery has a 20-year career in fine art and private wealth management.  She was Deputy and then Acting Director at the Neuberger Museum of Art and the Deputy Director at the Taft Museum of Art leading that institution through a major capital campaign, restructuring and ambitious design and construction project. Upon returning to US Bank after graduate school and 8 years at the Taft Museum, Ms. Emery became the Managing Director of Charitable Services, Private Client Group, US Bank, where her team served individuals with philanthropic intent and non-profit institutions throughout the country. Ms. Emery worked as a financial analyst at Christie’s during end of the 1980s art market boom and rejoined in 2012 as SVP, Business Director leading American Art, Latin American Art, Prints & Multiples, Books & Manuscripts, Photographs, and 20th Century Decorative Arts in the US.

After completing Christie's Management Development Program, she became Deputy International Commercial Director where she structured terms to secure the most coveted property for auction worldwide through guarantees, third-party guarantees, advances, enhanced hammer agreements and other profit sharing structures. Ms. Emery returned briefly to private wealth with the growing NYC office of Glenmede Wealth Management, an investment advisor that began as the family office of the Pew Charitable Trusts. Finally, Ms. Emery combined her experience in finance and art in art lending with Emigrant Bank Fine Art before joining a leading international fine art forensics firm, as its Consulting Director, US and founding Holly Tree Partners. She has a unique, well-rounded perspective on the portfolio value of art and luxury assets, understanding keenly how the tangible and intangible contribute. 

  • As MD, Charitable Services, Private Client Group at US Bank, she helped public and private foundations establish giving parameters, risk and endowment management strategies, branding, governance structures, mission/vision building, and served as the gatekeeper for several large private foundations. Ms. Emery also conceived and implemented mergers between foundations that were not efficient or sustainable on their own. Her previous experience as a portfolio manager, equity analyst and relationship manager at US Bank gave her the foundation to lead the Charitable Services Group.

  • Her work at the Taft Museum of Art (c. 1932, National Historic Landmark) required adapting the culture to raise public awareness, conducting a needs assessment among peer organizations, and implementing strategies to become a more integral part of the community in preparation for the Museum's first capital campaign. Ms. Emery lead fundraising and design/construction, but also developed the pro-forma post-expansion budget, double the previous budget size, and ensured that new programs and an appropriately expanded and equipped facility were in place to meet it.

  • For a three-month project at the Museum of Modern Art, Ms. Emery conceived and conducted a cost-benefit analysis of the proposed expansion considering equally the financial, social and mission enhancing aspects of the project to make the argument. The City of New York awarded MoMA $65m based on the resulting grant, which clearly demonstrated MoMA's economic and cultural benefits to NYC - past, present and post-expansion.

  • Returning to Christie's as SVP, Business Director, Ms. Emery leveraged her knowledge of finance, operations and the parameters of the art market to analyze her operating position and make quick, easily implemented changes that increased net profit in her group by 25% in one year. She created new financial reporting on an existing P&L platform that recast the information so that her team could understand and use it more strategically. Underpinning this financial success was a thorough review of operational risk and major changes to shipping and storage, successful negotiation and closing of outstanding insurance claims and legal disputes, and leading the internal facilities team through simple adjustments to warehouse HVAC to secure a major upcoming consignment.

Ms. Emery earned a BA in International Relations with a concentration in Art History from Mount Holyoke College, a MBA from the Carl H. Lindner College of Business at the University of Cincinnati and a MA in Arts Administration from the University of Cincinnati College Conservatory of Music.
