About Jeffrey Costello

Experience when it matters most! Jeff started his Real Estate career in 2004 when he went to work for a wholesale mortgage bank. That opportunity was his introduction to Real Estate. Jeff was instrumental in assisting brokers, bankers, and loan officers on qualifying, structuring and underwriting mortgage loans. In 2007 as the housing market was on the down side of it's peak, Jeff became a licensed agent and Realtor. Over the course of the next few years, Jeff went on to earn and achieve several coveted designations as well as navigate successfully through one of the toughest real estate markets of our time. Jeff attributes his experience, knowledge, work ethic and success to working through a distressed market which he believes makes him a better agent, representative, and member of his community. Jeff is currently a member of the National Association of REALTORS, Seattle King County Association of Realtors, Council of Real Estate Specialist and the Real Estate buyers Agent Council. His current endeavors include expanding his team of local experts, now known as the TribecaNW Realty Group, and educating buyers and sellers about the benefits of working with a team of full time real estate professionals over the individual agent. Jeff grew up in the Puget Sound area and has lived, worked, and played all over the region. When he isn't engaging with clients or selling homes, Jeff can be found with his wife and their three children. They really enjoy the outdoors, camping, hiking, and boating. Jeff also spends time getting involved and being active in his kids' hobbies, whether it's ballet, soccer, or swimming.

Lawrence Morris at Tribeca NW was phenomenal to work with. He worked tirelessly over four months to help me find the perfect home in Olympia, WA. He is an incredibly knowledgeable, patient, hardworking and trustworthy broker. I would absolutely recommend working with him and the group at Tribeca!

Benji went above and beyond in every aspect of our home purchase process. We've purchased many homes over the past 30 years and have never had an agent who was more helpful and available for us when we needed something. You wont find anyone with more integrity or a better work ethic. We highly recommend Benji and would definitely use him as our agent in the future.

Ben was knowledgeable, resourceful and professional. He listened carefully to what was important to me and presented me with options that would meet my needs. He was an excellent researcher and was able to gather information to help me make the best choice for myself and my future. He is a clear, kind and respectful communicator. I feel extremely confident in recommending Ben Meadow as your real estate professional.

Emily has been the best realtor! She went above and beyond every step of the way, communicating with us, making informed suggestions, and being our eyes and ears and feet on the property while we were buying from out of state. I recommend her a thousand times over. She helped us land a home we are really excited about and went out of her way to meet our needs.

We met Cameron Bruno by chance via a Zillow showing, and it was meant to be - Cameron became our buyers agent! Working with him, we witnessed his dedication and passion for his work. He cared about his clients, responded to our calls and messages almost immediately, worked tirelessly to get answers for our questions, even wrote our offer on the Christmas Day! He shared his knowledge and thoughts about the property with us to help us make an educated decision; he looked out for our interests and advised us every step of the way without making us feel pressured. He was also a creative problem solver when there was a missing storage key issue. He made buying a property easy and less stressful. His warm, caring, and responsive nature make him an above and beyond agent whom we highly recommend without hesitation. THANK YOU Cameron!
