Eric Sims Jr

For an attorney with decades of trial experience, true authority does not come from posturing. It comes from having seen it all, remaining steadfast in difficult moments, and never losing sight of the human being sitting across the table. Eric Sims Jr. brings that rare depth of perspective to the firm as a Senior Attorney.

Eric discovered his calling early, realizing in middle school that the legal system was meant to protect people during vulnerable moments. After earning his degree in Mathematics from Fort Lewis College, he completed his legal education at Southwestern University School of Law in Los Angeles. He began his path in public defense as an intern in 1993, joining the Public Defender’s Office full-time upon his admission to the Colorado Bar in 1995. Over eighteen years as a public defender, Eric handled high-stakes litigation, including seven homicide cases, and served on the Colorado Criminal Defense Board. In 2013, he founded his own practice, Flatirons Litigation, running the firm for over a decade before joining the team. Alongside his practice, he has trained rising trial attorneys as an instructor for CU Boulder’s Trial Advocacy course since 2009.

Having navigated the heaviest corners of the court system, Eric understands how overwhelming legal disputes feel for families. He cuts through the chaos of divorces and custody matters with a calm, grounded presence, helping clients separate raw emotion from strategic decisions. Eric believes every person has a story worth telling, and his focus in every consultation is simple: listen intently, offer complete honesty, and build a clear path forward.

What you may not know: Outside the courtroom, Eric stays grounded in the Colorado outdoors as a passionate mountain biker and gravel racer—even conquering the grueling Leadville Trail 100 MTB. A long-time vegetarian, Eric is married, comes from a close-knit family with four siblings across the state, and shares his home with two pugs named Clementine and Barrister. Beyond his legal career, some of his proudest memories stem from grassroots political activism, having spent time on the ground organizing for national campaigns.
