Reliable and pleasant to work with.

As a real estate broker I have confidently recommended Will Gillen as a go to attorney for my clients without hesitation. Working with Will and Christina ensures a smooth transaction no matter what issues may arise throughout the buying and selling process. Responsive, intelligent, and always with pl...easant demeanors, Will and his staff have always been reliable teammates. You can confidently choose Will Gillen for your real estate and wills and estates needs!

Smooth transaction

Will is very knowledgeable about Brooklyn real estate. He made the buying process easy and fast for this out-of-town buyer.

An excellent lawyer

William Gillen updated my will and established a trust for me. He also handled the change in ownership of my coop apartment to the trust abd advised me about how to handle many issues involved in these changes.

Great real estate attorney

We used Will for closing on the house we sold, and the house we bought. He was extremely helpful and knowledgeable, and always got back to me when I had a question to ask.

Two time home buyer and seller - Now Good Friend

Will has been a fantastic resource as we worked through both of our home purchases and subsequent sales. Will is extremely diligent, accomplishes tasks quickly, and is always willing to spend time working through complex topics with me. Will is flexible with his time and is always looking fo...r an opportunity to save money during negotiations. Working through legal paperwork involving these major life decisions can be extremely stressful and I would never want to put my family or my finances at risk. I can confidently say with Will as my lawyer I never once felt I was at risk or was putting myself in a bad position for sake of "getting the deal done". Truly a great professional, skilled at his craft, and has built an excellent team around him... would always recommend as the go-to lawyer.
