  Mark is an incredibly competent yet relaxed real estate professional. He was both super responsive as well as patient -- two important qualities for a broker to have! And he was able to minimize the stress of the home-buying process. I highly recommend him.

  I highly recommend Mark O'Brien. He is extremely knowledgeable about the NYC real estate market and went above and beyond in guiding us through the process. He took the time to understand exactly what we were looking for and tailored our search accordingly. We found the perfect apartment the first day of our search and closed a few months later. 5 stars!

  LOVED working with Mark and his team. Mark is very knowledgeable about real estate from condos to coops and everything in between. We enjoyed viewing apartments with him as he always pointed out something we wouldn't have considered about the building, unit, etc. He was extremely helpful during the initial offer to contract negotiation and very hands-on during the coop application / board interview process. I'd work with Mark again and recommend him to friends and family.

  Mark was incredibly patient and easy going. When we first approached him, we had no idea what we were getting into. He listened to all our crazy ideas, and spent plenty of time showing us properties.
  As a New Yorker, he knows the market well and tried his best to educate us.
  When it was time for the closing, he helped us every step of the way. Mark and Courtney (his assistant) made the process less painful.
