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!

The best in Brooklyn probably the world

We worked with Will on the sale and purchase of 2 properties in Brooklyn. He was already readily available for all our questions and to walk us through documents and procedures that were new to us. He was the upmost professional in a particularly challenging closing conversation and has always been o...n our side. I would recommend Will to anyone

Thank you, Will! You are the best attorney we've worked with!

Wife and I just sold our house in Brooklyn from our new home in California. Will was hands down the best attorney we've worked with and he made the process clear and easy, from start to finish - this was made especially challenging given COVID and being across the Country. Will had our confidence fro...m the first minute and kept it throughout the closing - and he came with a very strong recommendation from our broker, so his reputation is known widely across the Brooklyn market. Thank you, Will, for making a challenging experience a pleasure. If we have real estate attorney needs in NY again, we will be coming back to you. Thank you!

Skilled real estate professional

Had an excellent experience. He handled last minute problems that inevitably popped up, right to the morning of the closing, masterfully. Always responsive to our questions and concerns. Will certainly use him again for future real estate transactions.

Outstanding Service

I would highly recommend Will to friends and family. He was knowledgeable, attentive and consistently went above and beyond to ensure my successful real estate closings.

What determines Avvo Rating?
  • Experience & background Years licensed, work experience, education
  • Legal community recognition Peer endorsements, associations, awards
  • Legal thought leadership Publications, speaking engagements
  • Discipline Disciplinary information may not be comprehensive, or updated. We recommend that you always check a lawyer's disciplinary status with their respective state bar association before hiring them.
