I’ve worked with several galleries in the past, but Goodson Gallery and Mike Vallone stand out because of their personalized service. They took the time to really understand my interests and goals as a collector.

I needed help selling a few high-value antiques that had been in my family for generations, and Goodson Gallery made the process incredibly easy. Mike Vallone connected me with top auction houses and collectors, securing prices far above what I had expected.

Working with Mike and Goodson Gallery was a game-changer for my art collection. I was looking for very specific pieces, and their team not only sourced exactly what I wanted but also negotiated excellent prices on my behalf. The entire process was seamless from start to finish, and I couldn’t be happier with the investment. Highly recommend them for anyone looking to expand their art portfolio!
