The Team
Behind the Envelope
Licensed architect. Structural engineer. Building inspector. Construction principal. Project manager. All on staff, all under one contract — the in-house team behind every CRDG envelope project.
Darren Flynn
Managing Principal
“Darren started in construction and spent fifteen years on Chicago rooftops — steel, waterproofing, structural framing — learning every system in the building envelope from the top down. In 2009 he founded the firm. Today he runs a 60-person operation with in-house architects, engineers, and tradesmen, all under one contract. Twenty years in construction taught him one thing: if you're managing the building, you shouldn't have to manage the contractor too.”

Mike Ryan
Architect, Principal
“Twenty years of Chicago permits, code reviews, and Department of Buildings hearings — Mike knows the regulatory side of construction the way Tom knows the field side. He architects the scope, pulls the permits, and walks clients through what's coming so there are no surprises on their end. Facade ordinance compliance, zoning variances, structural modifications — if it needs a stamp, Mike's already working on it.”

Tom Bartosiewicz
Construction Principal
“Tom came up through heavy civil — roads, bridges, infrastructure — before turning that engineering discipline loose on Chicago's building stock. Three thousand projects later, he still walks every site before his crews touch it. Mortar joints, membrane failures, corroded lintels — he reads a facade the way most people read a blueprint. His team doesn't patch problems. They fix root causes.”

Christi Malone
Building Inspector, Architect
“Christi is the firm's lead building inspector. She has been inspecting Chicago buildings since 2015 — facade condition assessments, structural evaluations, ordinance compliance reviews — after two decades practicing architecture. She holds a Master of Architecture from Arizona State and knows what failure looks like before it reaches the surface: the hairline crack that means embedded steel is corroding, the efflorescence that traces a moisture path, the mortar joint that's taken one too many Chicago winters. Her inspection reports are where every scope of work begins.”

David Petlicki
Structural Engineer
“David is the firm's structural engineer — the one who determines whether a building can take the repair, the addition, or the load before anyone picks up a tool. BS and MS in Civil Engineering from UIUC, ten years across commercial, institutional, and adaptive reuse projects. He runs the structural assessments, calculates the lintel capacities, and stamps the drawings. When the facade report says something's moving, David figures out why.”

Kevin Wojtas
Project Manager
“Kevin is the person holding every moving piece together. He coordinates between architects, engineers, and field crews to keep envelope projects running — permits filed, materials staged, schedules tight, owners informed. UIUC-trained in landscape architecture, he thinks in systems and site logistics. Nothing ships late and nothing falls through the cracks on his watch.”
