  • John and his associates at Gasdaska Conlon are top notch professionals. It was a very smooth, easy and overall enjoyable experience working with them to buy and sell our apartment in NYC. They are motivated and efficient, and very easy to communicate with. I highly recommend them to any buyers / sellers out there!

  • I wanted to share the excellent experience I had dealing with the GVC Real Estate Team at Douglas Elliman. I worked with John, Daniel and Jessica to sell my condo. Once listed, the team promptly coordinated all aspects of the process including photos, video, staging. They worked tirelessly and conducted open houses and showings until we were in contract. They even handled the final walk through items. I would only work with this team in the future.

  • I 1000% recommend choosing the Gasdaska Conlon team. 1) As a first-time buyer, I could not have asked for a more supportive team. John and team were always ahead of my needs. 2) Touring apartments can get overwhelming really quickly. John made the experience so enjoyable I secretly hoped I'd never find a home. Great thought partner, always looking out for you, tells you the truth even if not pleasant/not what you want to hear 3) The team (specifically Daniel) was extremely diligent and communicative, ensuring all my questions were answered 24/7. 4) Patience. I really appreciated John and team's patience throughout all the times I changed my mind about what I was looking for.

  • John Gasdaska and Jonathan Conlon are truly outstanding. When we first decided to buy an apartment in Manhattan they listened to us very carefully and during a short visit, found us the perfect match. They and their great team held our hands and navigated us throughout the entire, unfamiliar, purchase process. Then at the other end of our ownership, when we needed to move on, they achieved an excellent outcome for us in a very short time, despite a challenging market. We could not recommend them more highly and hope to do business with them again.

  • I have had many experiences buying and selling Real Estate. My experience with the GVC Real Estate team was by far the best. They were honest and very experienced from start to finish. They handled everything, from the listing, pictures, to staging the Apt. for us. They were able to make recommendations and service providers to paint, clean and get the Apartment ready. We did not need to do much. I highly highly recommend the whole John Gasdaska team at Douglas Elliman.

  • My family worked with the GVC Team over the course of 2+ years to successfully sell two apartments in a small UES co-op in the East 70s. John and Jonathan and their entire team were professional, very responsive and outcome oriented. I would recommend them to anyone needing co-op sale assistance. Top rate!

    Edward Whittemore
  • I worked closely with John Gasdaska on the purchase of my first apartment. He was communicative, honest, kind, and exceedingly helpful throughout. Buying an apartment in New York City is a complicated--often terrifying!--process, and John was there as both a guide and a friend for the entire process. His team, namely Daniel Champoli, made the co-op board process a breeze due to his exceptional organizational skills. I am by nature a skeptical anxious person, and so at every turn I was expecting disaster, but the GVC team made sure that I was completely taken care of from start to finish.

  • I am a realtor in Orange County, California and I referred a client to John Gasdaska to work with. They were first-time home buyers. I knew John was the right recommendation for my client based on his knowledge and his style. He successfully navigated my buyer to a successful closing which my client is super happy with and had a great experience.
