"I was referred to Mike by another appraiser to handle the valuation for my divorce case, and I'm so glad I was. He was professional, easy to work with, and delivered the report faster than I expected. The appraisal itself was extremely well supported — every part of it was backed by clear market data and solid reasoning. Both attorneys commented on how strong the report was, and the other party had nothing they could challenge. It made a stressful situation much easier to navigate. I couldn't recommend Mike more."
