"David was great to work with. He took the time to understand my concerns, made meaningful improvements to my agreement, and clearly explained the reasoning behind his recommendations. He was thorough, responsive, and easy to communicate with throughout the process. I’m very happy with the final result and would definitely work with him again."

"David was excellent to work with. I brought him self-drafted documents for an LLC membership transfer and asked for a review instead of a from-scratch draft. He turned it around quickly, strengthened the agreements with protections I wouldn't have thought of, and answered all my questions clearly. I'd gladly hire him again and highly recommend him."
