Leading Elegran Real Estate Teams Join Coldwell Banker Warburg's Expanding Agent Roster

Elegran's Asset Advisory Team and Waterview Advisory Group join three additional agents who recently moved to CBW

NEW YORK, Aug. 12, 2025 /PRNewswire/ -- Coldwell Banker Warburg (CBW), the premier brokerage that's been at the forefront of New York luxury real estate for more than 100 years, is pleased to announce that two high-performing teams are joining the firm from Elegran Real Estate: The Asset Advisory Team and the Waterview Advisory Group. In recent months, 25 real estate brokers and agents have joined CBW from Elegran and other leading brokerages and firms.

"We're thrilled to welcome not one, but two exceptional teams to Coldwell Banker Warburg. The fact that they've chosen CBW as their next home is a testament to the culture we've built, the standards we uphold, and the future we're creating together," said Kevelyn Guzman, Regional Vice President of Coldwell Banker Warburg. "The Waterview Advisory Team is a powerhouse — they're analytical, growth-focused, and bring a modern investment approach to every deal. The Asset Advisory Team leads with integrity, collaboration, and a strong track record of client success. I'm excited about the road ahead and proud to support their continued growth."

The Asset Advisory Team, which has amassed more than a quarter of a billion dollars in lifetime sales, is led by Ashley Reidy Quinn and Nick Montalbano. Quinn co-founded the team with Montalbano, and in addition to overseeing and generating the team's sales and rental transactions, she leads its operations, marketing, and client experience strategy with precision and a commitment to excellence. She also earned the distinguished Real Estate Board of New York's "Rental Deal of the Year" award during her first year in the business. Montalbano leads the team's business development and sales strategy. The team's transactional range spans Manhattan, Brooklyn, and the Hamptons, and includes work within prominent properties such as 212 Fifth Avenue and 33 East 74th Street.

"We are truly excited to make this transition to CBW and honored to join such a distinguished and respected firm. The level of support and professionalism we've already encountered has been exceptional," said Quinn and Montalbano. "We're confident this move represents the best path forward — not only for our clients, but also for the continued growth and success of our team."

The Waterview Advisory Group has an impressive quarter of a billion dollars in transactions across New York and globally. It provides a wide range of agent and advisory services, ranging from residential sales listings, buyer representation, rental listings, property investment analysis, in addition to commercial real estate sales and rentals. As a whole, the team prides itself on a balanced left-right brain approach to real estate — identifying intrinsic real estate value, while staying mindful of the heart and soul of its clients' goals. The Group is led by its founder, agent Jules Garcia, a former regional vice president and 20-year financial services industry veteran. He focuses on upscale townhouses, new developments, and multifamily properties in Brooklyn and Queens.

"As a team, we believe in long-standing partnerships, and joining Coldwell Banker Warburg gives us the ability to maintain a specialized boutique approach, while accessing a behemoth of a global network of real estate resources," said Garcia. "The more research we did as a team, the more we knew that Coldwell Banker Warburg would be the right partner going forward, due to its goal of elevating both the residential and commercial real estate markets."

Below is an overview of each team's agents, with a bit about each individual:
