The Siren Story


Siren is built on optimism, determination, and the premise that clear communication makes everything, and everyone, stronger. In 2012 co-founders Lindsey (Walenga) Grosso and Adela Piper left steady nonprofit jobs to launch Siren and nearly everyone advised them against it.


Those well-meaning folks said not to go into business with your best friend, not to be 50/50 partners, and couldn’t believe it when Lindsey and Adela left behind stable jobs when the economy was still shaky. But Siren launched anyway, because comfort does not foster growth. 


Siren started out as two fiercely motivated communication professionals who wanted to tell stories that mattered in Detroit and across Michigan. And they did. Each year Siren attracted more clients and grew its reach while growing its team. Siren defined its greatest value as strategic communication and has helped dozens of organizations craft powerful messages that resonate with their target audiences.


Lindsey and Adela have weathered the wild ride as founders and mothers, on the way to building a company that is changing the way organizations communicate with the people who need them.  Along the way they learned how to become stronger leaders and communicators.


In its first ten years Siren grew from an idea to a company creating impact across two locations statewide. 


Then, in 2023, an unimaginable loss occurred with the sudden and unexpected passing of co-founder, Lindsey (Walenga) Grosso. The loss of Siren’s first CEO, its visionary leader, and its dear friend shook the firm to its core. Through the loss, Siren remains strong and in service to its valued clients. 


Today, the Siren team is dedicated to carrying on Lindsey’s legacy through the continued success of the company. Lindsey believed that clear, powerful communication is transformative. Siren operates with that principle at the forefront of its strategy and approach, dedicated to making a lasting impact for its clients.
