Strategic Advising for Social Change

We live in a time where change is badly needed but difficult to achieve. True impact requires expertise and commitment. The Wren Collective provides both to clients who want to take the bold action needed to radically transform the criminal legal system.


Our Services



We design full-throttle campaigns to achieve change.  We craft messages, identify those who can effectively communicate them, and determine how and when they should be delivered.  We will show you which levers need to be pulled to obtain radical transformation, and then we help you pull them.



We design ballot initiatives and legislation and provide the research and strategy necessary to get them passed. We help clients throughout the process, tracking amendments, identifying whether proposed changes will harm the client’s goals, and developing strategies to oppose these modifications when necessary.



We provide a rapid response strategy in a crisis, helping to mobilize those voices that can help combat an attack.



We perform deep, evidence-based research to identify the solutions that will help our clients achieve their goals. We write position papers, reports, policies, and white papers, and then distill them into clear messaging to help you push for change.



We help place stories in all forms of media—print, digital, radio, and television—to get our clients' message to the widest audience possible.



As long-time criminal defense lawyers, we can provide specialized media and strategy support for your litigation.


Our Vision

The Wren Collective is a strategic advising firm that provides our clients with significant substantive knowledge, experience, and an unparalleled work ethic. We are lawyers and policy experts who deploy our considerable criminal justice system expertise to provide communication, policy, legislative and campaign support.


We are not your ordinary firm:


  • We are deeply client-centered. We are a boutique firm that is entirely focused on achieving our client's end goals—meaningful change. We are selective so that we can give our clients as much time and attention as they need.

  • We believe subject matter expertise matters. Successful communications and policy work requires people who understand both how things do and should operate. We have that expertise. 

  • We believe hands-on experience is critical. We have been in the trenches, both in courtrooms and on campaigns. We understand how to create targeted and effective advocacy.
