"After the Walls is not merely a narrative about prison; it delves into the crucial elements of accountability and integrity in decision-making. Sean illuminates how success can subtly distort our judgment and how ethical drift can creep in, one rationalization at a time. Throughout my career, I have witnessed this unsettling pattern in companies and boardrooms. Every founder, executive, and investor should read this ethical decision-making book before they face pressure, to equip themselves for overcoming ethical drift, not after." —Brad Feld, Partner, Foundry, Co-Founder, Techstars
“Sean Mueller has written an ethical decision-making book that refuses to take the easy way out. After the Walls is painful, honest, and deeply human. It addresses bad decisions, yes, but more importantly, it delves into what comes after them: accountability and integrity, humility, family, second chances, and the daily work of overcoming ethical drift to become someone who can be trusted again.”

This ethical decision-making book offers valuable lessons not only for business professionals and students but also for anyone interested in overcoming ethical drift and striving to live with greater purpose, humility, and character.”

“After the Walls is a rare and courageous account of what happens when ambition outpaces integrity. My dear friend Sean Mueller doesn't flinch from the hard truth that ethical failure seldom arrives in a single moment; rather, it accumulates, quietly and insidiously, through choices that once seemed harmless. Each decision makes the next one a little easier, until the ground beneath you simply gives way. He stood on a concrete ledge above a Denver street in April 2010 and stepped down not because the path forward was clear, but because his sons needed a broken father more than an insurance settlement. What followed was fourteen years of rebuilding, encompassing dog kennels and late-night chow hall debates, losing his mother while behind those walls, and saying goodbye to a brother via a phone pressed to someone else's ear. Eventually, integrity ceased to be just a talk; it transformed into a lived reality, highlighting the importance of accountability and integrity in our actions.
In a world that too often rewards speed over substance, this ethical decision-making book serves as a timely reminder that enduring success, genuine respect, and peace of mind are only built on ruthlessly honest conduct. What Sean carries out of that suffering isn’t merely a cautionary tale. It’s a map, drawn in the dark, designed for anyone who needs to find their way back from the brink of ethical drift. I recommend it without hesitation to anyone who leads, aspires to lead, or simply wants to live with greater purpose and intention.”

“Courageous, witty, and engaging. After the Walls is a brilliant exploration of moral drift, social pressure, and ethical compromise. Sean invites readers into the worlds of finance, fatherhood, prison, and redemption in a style that makes this ethical decision-making book hard to put down.” —Ben Boyce, PhD
“I had the privilege of knowing Sean Mueller as a friend, brother, and fellow student of personal transformation during our years together in prison. As someone who shared that journey with him, I witnessed his evolution from a man confronting the consequences of his choices to one committed to education, service, and ethical leadership. After the Walls provides a rare and candid examination of accountability and integrity, as well as the difficult work of rebuilding character after failure. It is a valuable resource for professionals, educators, and leaders, guiding anyone seeking to understand how integrity is lost, how it can be reclaimed, and why personal accountability remains the foundation for overcoming ethical drift and achieving lasting success.” —David R. Carrillo, MBA, Founder/Owner of David R. Carrillo, Consulting, LLC, Lead Facilitator Legislation Inside, Author, Public Speaker
“After the Walls is an essential read for anyone involved in fraud prevention—not just because it details how schemes are constructed, but because it highlights something far more crucial: how good people can quietly drift into unethical behaviors. Sean Mueller’s account of his own downfall underscores that ethical failure is rarely a sudden choice; rather, it develops through small compromises and rationalizations. His honesty in discussing these psychological conflicts offers valuable insights into accountability and integrity, particularly when one compromises what they know is right.”

“After the Walls is an insightful ethical decision-making book for professionals at the start of their careers and college students. Understanding compliance and legal responsibilities gains new significance when viewing a real-life securities fraud case. In After the Walls, Sean’s integrity was never the issue in high-pressure situations—his struggle illustrates the challenge of overcoming ethical drift. This narrative serves as an antidote for anyone needing heightened self-awareness regarding their values in the business world.”
