We provide comprehensive, precise, and confidential fine art appraisal services.

Our reports are USPAP compliant and adhere to the Code and Ethics of the Appraisers Association of America.

When the unexpected occurs, having an experienced advocate in your corner makes all the difference. We work closely with collectors, institutions, and their insurers to deliver accurate, well-documented valuations that protect the full value of your holdings. Our process is thorough and sensitive to the urgency these situations demand— helping you to safeguard your valuables and secure peace of mind.

We determine the accurate replacement value for coverage compliance within your insurance carrier's requirements. The appraisal document includes color digital images and full descriptions for each item, with values supported by appropriate market comparables. 

In the event of damage or loss, we can also advise on conservation, restoration, or sale and assist in settling claims or disputes. Reports are accepted by all major fine art insurance carriers, with direct integration for streamlined quoting. 

Giving art a meaningful second chapter is one of the most rewarding aspects of this work. We provide IRS-qualified appraisals for charitable contributions to museums, universities, and nonprofit organizations, ensuring that your generosity is properly recognized and your deduction is fully optimized.

We take the time to understand the significance of each piece you choose to give, bringing the same care to your philanthropic goals as we do to every other facet of our work.

All non-cash charitable donation reports are backed by transactional data and market analytics, and are fully compliant with IRS requirements for qualified appraisals.

Our work is conducted with discretion and deep respect for the legacy you have built — helping to ensure that your collection is understood, valued, and stewarded according to your wishes for generations to come.
