I have been using Eva Lohrer as my accountant and tax preparer for the last 9 years. She is great! Quick to respond, accurate, and very knowledgeable. And her fees are reasonable considering the quality of the work performed.
I have gone to their auctions both in-person and online. They handle everything very professionally, which is not true of many other companies. They understand what the value of items should bring at auction and run everything in a very caring way. I would trust them with my parent's estate.
