Erin Erenberg, co-founder and CEO of the nonprofit Chamber of Mothers (CoM), has worked tirelessly advocating for maternal rights in the U.S. As the organization enters its fifth year, Erenberg reflects on the fight for paid leave, affordable childcare, and improved maternal health - the three main focus areas for CoM. With over 10,000 members across 48 chapters in 33 states, Erenberg has built a powerful coalition of mothers to push for policy changes at the local, state, and federal levels.

Why it matters

The Chamber of Mothers is the largest nonpartisan nonprofit advocating for maternal rights in the country. By pooling the political will of mothers, the organization aims to ensure supported motherhood experiences for all, addressing key issues like paid family leave, affordable childcare, and maternal health that impact millions of American families.

The details

Erenberg founded CoM in 2021 after seeing the overwhelming challenges mothers faced during the pandemic, from juggling remote schooling to managing increased caregiving demands. Frustrated that issues impacting mothers were not being prioritized, Erenberg assembled a group of 8 other mothers to build a coalition focused on driving policy changes. Over the past 4 years, CoM has grown rapidly, establishing 48 chapters across 33 states with over 10,000 members. The chapters, typically led by 3 volunteer facilitators, take action based on the needs and legislative opportunities in their local communities, ranging from testifying before state legislators to simply joining the mailing list.

  • CoM was founded in November 2021.
  • The organization has grown to 48 chapters across 33 states in just 4 years.
  • In 2026, CoM is celebrating its 5th anniversary.

What they’re saying

“Until moms' concerns become mainstream concerns, our politicians are not focused on them. By collecting our political will, we will create change.”

— Erin Erenberg, Co-founder and CEO, Chamber of Mothers

“Moms have way more in common than we're led to believe. The division that has happened among moms– Do you breastfeed or formula feed? Do you send your kids to daycare or are you a stay-at-home mom? —many times is a false structure that is meant to keep us fighting and distracted so we don't come together and insist on what we need.”

— Erin Erenberg, Co-founder and CEO, Chamber of Mothers

What’s next

In 2026, the Chamber of Mothers plans to continue expanding its network of local chapters and pushing for federal legislation to provide paid family leave for all American workers.

The takeaway

The rapid growth of the Chamber of Mothers demonstrates the power of mothers uniting to advocate for policy changes that support families. By building a nonpartisan coalition and focusing on issues with broad public support, the organization is making meaningful progress in ensuring all mothers have access to the resources and support they need.
