Gereon Wiese provides personalized real estate guidance in English, German, Chinese, and French, creating a seamless experience for clients from diverse backgrounds. With clear communication and local expertise, every step of the journey is handled with confidence and care.
A political scientist and former German diplomat, Gereon Wiese brings careful preparation, skilled negotiation, and an international perspective to real estate in New Jersey.
Before entering real estate, Gereon’s career in diplomacy and foreign policy required sound judgment, discretion, and the ability to navigate complex situations. Today, he applies those same qualities to helping clients buy and sell homes, with clear communication and close attention to detail throughout the process.
We have been living in the same home for 40 years, and Gereon understood all the emotions, he guided us to help find the right buyers for our home. Even during complex transactions with multiple moving parts, Gereon never drops the ball. Gereon constantly goes above and beyond his actual responsibilities to keep everything exactly on schedule. Beyond his phenomenal professional skills, his honesty, genuine character, and noble integrity truly stand out. He only wants the best for his clients and handles multiple transactions at once with absolute ease. You cannot go wrong choosing him—hiring anyone else is a mistake!

Working with Gereon was an absolute game-changer. He is incredibly hardworking, always available, and meticulously tracks every single detail, meeting, and inspection. We first met Gereon while looking for our dream home. Along this journey, I met a lot of agents, none however, came close to his level of care, follow-up and help to find our dream home.

We’re so happy we chose to work with Gereon on the purchase of our new home. Throughout the entire process of selling our home and buying a new one, we found him to be our most trusted resource. In what was arguably one of the most stressful experiences of our lives due to factors out of our control and other parties involved, Gereon never once disappointed us and for that we are truly grateful. To say he went above and beyond for us would be an understatement.

Gereon was meticulous throughout the entire process! Actually both processes; he helped us with a challenging sale of our large mixed-use property, as well as helped us rent a cozy townhouse to call our new home. He always went above and beyond what was expected. Plus he genuinely cares and I’m happy to have met him. He’s not just a great agent; I consider him a friend.

Gereon is an excellent agent who we highly recommend for anyone's real estate needs. He was attentive through the whole process, keeping us informed of every move, making us aware when paperwork was emailed for signatures or review. He is such a good agent that he noticed we could use help in clearing a room for our open house. Without hesitation, he helped us clear that room. It was spotless in about 1.5 hours, which helped the open house to be very successful, and we were offered a price above our asking price. Excellent job! Due to his diligence, we were able to purchase our new home in PA the same week as ours sold! Gereon is a very thoughtful, kind person, and I am sure he will be very successful in his future dealings. He makes you feel like he is a friend rather than just a real estate agent.

He was amazing with the purchase of our dream home and was always attentive to our needs! He was amazing to work with as well and always ensured we were good to close.

Gereon, almost immediately after we inquired about a listing, reached out by phone & email, walking us through the rental process since we never dealt with an agent before, set up a viewing date within days for multiple properties & inside of 10 days negotiated and locked up a lease for us. I never had such a quick turnaround (2 weeks after finding out we had to move!) & we owe it all to this guy. In a normal world we would have been searching for months. The only problem now is...we can't pack fast enough!

We had a wonderful experience with Gereon. From start to finish, we worked together very closely. He consistently made sure to keep us informed, and was always available to answer any questions.

We were extremely pleased with Gereon Wiese and Sotheby's throughout the process. He is an excellent agent, attentive to every one of his client's needs and incredibly responsive at every step of the way. We were very fortunate to have him work with us on both the sale of our home and the purchase of a new one. In a very competitive NJ housing market, we couldn't be happier with the outcome. His in-depth knowledge of the market dynamics was a significant factor in the success we realized. Without question, we would highly recommend Gereon to anyone looking for an agent in NJ.

We recently moved our family of four from a New York City apartment to a house with a garden in New Jersey, and working with Gereon made the process remarkably smooth. It was a pleasure to speak with someone who understands both our languages - and our needs. He preselected such great homes that we only had to tour homes for one day. He's personable and wonderful with kids. Throughout the entire process, Gereon made us feel comfortable and was always reachable - even checking in after we moved. We couldn't have asked for a better partner in finding our new home.

Gereon is truly one of the best realtors, his knowledge, dedication to his clients and his ability to go above and beyond was exceptional. We are really very blessed to have met him and had the opportunity to work with him on both my purchase and the sale of our home!
