What exactly do I do?

I’m a polymath with a strong background of both academic and practical work involving the prized possessions of mankind, their creation, and their custodianship. I apply and share that knowledge in tailored USPAP compliant documentation that is supported by rigorous testing against industry standard criteria;

I appraise.

I’ve been lucky enough to work with many large names in luxury, departments of the US government, museums, foreign and domestic dignitaries, celebrities, royalty, and other high net worth individuals for many years.

I’ve also had the opportunity to collaborate with some of the finest professionals in the field, and maintain a strong network of specialists that I can reach out to for specific guidance and assistance when my own experience on an item proves thin. Individuals like this are an invaluable resource to any serious appraiser.
