Leadership credentials are typically measured by title, tenure, and business results. By those metrics, Daniel J. Cullen — Director at Precision Metal Fab, nearly two-decade veteran of construction and manufacturing, and Delafield, Wisconsin-based executive — holds his own against any peer in his industry. But a fuller picture of who Cullen is as a professional and a person requires looking at what he does when the work day ends.
Rock Steady Boxing: Instruction With Real Stakes
Among the more distinctive lines on Daniel J. Cullen’s profile is his role as a Rock Steady Boxing instructor. Rock Steady Boxing is a specialized fitness program designed for individuals living with Parkinson’s disease. The training — rooted in non-contact boxing — targets the neurological and physical challenges that Parkinson’s presents: balance, coordination, strength, and reaction time.
Instructing in this environment requires more than fitness knowledge. It requires patience, attentiveness, and the ability to adapt in real time to participants whose needs and capabilities vary from session to session. For Daniel Cullen of Delafield, this role is a direct extension of the same people-focused orientation that characterizes his leadership at Precision Metal Fab. It is work that demands presence, care, and consistency — and it matters in ways that are immediately visible to the people in the room.
Teaching at Waukesha County Technical College
Daniel J. Cullen also presents at Waukesha County Technical College, contributing to the development of students preparing to enter professional and technical fields. That engagement places him in a role that many executives with comparable experience rarely take on: direct, face-to-face knowledge transfer with the next generation of workers.
For someone with nearly twenty years in construction and manufacturing, the value of that contribution is concrete. The gap between academic preparation and workplace reality is a persistent challenge in technical fields. Professionals who step into that gap — who bring real operational experience into an educational setting — do something that curricula alone cannot accomplish. Daniel J. Cullen of Delafield is among those professionals.
Service at St. Anthony’s on the Lake
Cullen serves as a catechist at St. Anthony’s on the Lake, a role that reflects a different kind of commitment — one rooted in faith and in the responsibility of passing along something that matters beyond professional achievement. Catechesis is a teaching vocation, and it draws on the same core disciplines that distinguish effective leaders in any context: clarity of communication, sustained engagement, and the willingness to show up consistently for others.
This dimension of Daniel J. Cullen’s life is not incidental to who he is professionally. It is part of the same coherent character — someone who takes the transmission of knowledge and the development of others seriously, regardless of the setting.
A Published Author
Cullen is also a published author — a discipline that demands a quality of sustained intellectual focus that is distinct from the demands of executive leadership, even as it complements them. Writing at a publishable level requires the ability to organize complex thinking, sustain an argument across length, and communicate with precision. That Daniel J. Cullen has done this alongside an active career in manufacturing and fabrication leadership speaks to a breadth of engagement that is, by any measure, uncommon.
What the Full Picture Reveals
Taken together — the executive role at Precision Metal Fab, the Rock Steady Boxing instruction, the college presentations, the catechesis, the authorship — the profile that emerges is of someone for whom leadership is not a job function but a consistent orientation. Daniel Cullen of Delafield brings the same qualities to each of these roles: preparation, accountability, and a genuine investment in the people he is working with.
In manufacturing, those qualities have tangible business consequences. At Precision Metal Fab, they are shaping the company’s direction. Beyond it, they are leaving a mark on the individuals and communities Daniel J. Cullen engages with every day.
