  • John Costello to streamline development functions as CDO

  • Nadia Sesay to lead new Community Growth and Development team


October 29, 2020 [DETROIT] – Bedrock is pleased to announce today the addition of three C-Suite leaders to help guide the 9-year-old Detroit-based real estate company into its next decade of visionary development. Ivy Greaner, Chief Operating Officer (COO), is to start Nov. 16., and John Costello, Chief Development Officer (CDO) will take on his new role beginning Monday, Nov. 2. Nadia Sesay will become Bedrock’s first Chief Community Growth and Development Officer starting Dec. 4.

“Ivy, John and Nadia are the perfect additions to the talented team at Bedrock as we continue the important work of curating vibrant spaces and places, while working together to uplift the broader community,” said Kofi Bonner, Bedrock CEO. “Our programs and developments must represent and support the full diversity of Detroit and whenever possible encourage growing wealth and improving health outcomes, and I look forward to working with these leaders to better accomplish these imperative outcomes.”

Greaner has nearly 30 years of experience as a real estate executive and investment leader of retail, commercial and multi-family projects in every region of the United States, from the Midwest, to the South to the West Coast. Most recently, she served as Executive Vice President and COO of Chicago-based InvenTrust Properties, a premier retail Real Estate Investment Trust (REIT) that owns, leases, redevelops, acquires & manages open-air centers totalling 11 million square feet. In one of her prior roles, she was Partner and COO of Ram Realty Services in Detroit and was on the leadership team that developed the city’s first Whole Foods Market in Midtown.

In Greaner’s new position as COO at Bedrock, she will be responsible for the day- to-day administrative and operational functions, ensuring a seamless experience for our visitors, residents, and tenants.

Costello joins Bedrock from FivePoint Holdings (formerly Lennar Urban) where he served as Executive Vice President of Commercial for the last five years. Over the course of his 35-year, bi-coastal career in development, he has built upwards of 10,000 residential units and a total of some 21 million mixed-use, residential and commercial square feet across the United States.

In his role as CDO at Bedrock, Costello is tasked with streamlining overall development functions across the enterprise at a pivotal moment for landmark projects like the Hudson’s Site and Book Tower, and as Bedrock makes its first foray into the industrial sector.

In a brand-new role for Bedrock, as Chief Community Growth and Development Officer, Sesay will be leading a team focused on making meaningful connections between Bedrock’s expertise and the growing communities of Detroit and Cleveland.

Sesay comes to Bedrock from the City of San Francisco’s Office of Community Investment and Infrastructure, where she served as Executive Director. In this role, she was responsible for the economic development of the new Transbay, Mission Bay and Hunters Point Shipyard neighborhoods, which collectively provide over 20,000 new housing units, including approximately 7,000 affordable housing units, 400 acres of parks and open space and 10 million square feet of commercial space.

In addition to the above leadership additions, CEO Kofi Bonner has created a Strategy and Innovation Team comprised of four professionals charged with sourcing and incubating special projects and programs.
