Related’s Avi Kollenscher Joins Nightingale Properties 

Avi Kollenscher has joined Nightingale Properties as EVP. In a newly created position, Kollenscher will support CEO Elie Schwartz, leading investment activities, including investment origination, execution, and capital formation. Together with other executive team members, he will oversee development, leasing, and portfolio management efforts. 

“As Nightingale continues its rapid growth, we needed to expand our leadership team,” said Schwartz. “Avi’s extensive experience in the industry is a perfect fit for our team and our strategy, making him ideally suited to lead our investment efforts. We are all very excited to have him on board.” 

Kollenscher joins Nightingale Properties after a two-decade tenure at Related Companies, where he most recently served as SVP. There, he oversaw large-scale development projects exceeding $2 billion across multiple property types and managed a three-million-square-foot retail portfolio.  

Before joining Related, Kollenscher was an analyst in the real estate investment banking group at UBS Investment Bank.
