I just finished reading [the] inventory report narrative. The entire report format is so easy to read and understand. The item reporting consistency is great. What a relief it is to have this overwhelming task done so professionally and at arms-length.

Your work is superb!

Brooke helped me sort through generations worth of my neighbor’s collected items to settle her estate. She has great knowledge and instinct for value and markets and is very pleasant to work with. She is trustworthy and maintains great communication throughout the process and found creative ways to hold a safe sale in the middle of the pandemic. I highly recommend her services.

I reached out to Brooke for help in valuing my grandmother's 1927 bedroom set. She was a pleasure to speak with on the phone and quick to get back to me with the much needed information. I highly recommend her and will be using her for more valuations as I search through my mother's estate.
