Run by owners. Built for builders.
ACG is run by its two co-founders - Rielly and Connor Walsh, wife and husband. Every scope, every change order, every schedule commitment is an owner-level decision made by an owner.

A company is its operators.
Large glazing subcontractors hide behind layers of project engineers and regional managers. The GC who needs an answer never gets the person who actually makes the call. ACG is the opposite of that. The two people running the company are the same two people answering the phone.

Education
Middle Tennessee State University - B.S., Concrete Industry Management. MTSU is one of only four schools in the United States offering the specialized CIM program - a degree built directly with the American Society of Concrete Contractors and funded by the concrete industry itself. It is the closest thing in U.S. higher education to a trade-grade construction degree.
Prior experience
The Estates at Aqualina - lead superintendent, exterior stoneworks. Aqualina is the ultra-luxury oceanfront tower in Sunny Isles Beach where the stone facade, tile balconies, and exterior finishes set the building's entire identity. Running the exterior stone package there meant coordinating specialty trades, European material lead times, and luxury-grade punch standards - on a site where nothing short of perfect gets signed off.
At ACG
Rielly is CEO, co-founder, and the company's 51% majority owner - the basis of ACG's woman-owned status. She makes the calls on strategy, growth, and long-term direction: the Naples and Tampa office expansions, the operating discipline that sets ACG apart from legacy subcontractors, and the flagship manufacturer relationships with ESWindows and Euro-Wall.
Her background in concrete and stone is the unusual edge: most glazing executives have never worked the exterior envelope from the other side. Rielly has. She reads a building the way the GC does - in layers, sequences, and interfaces.
Connor Walsh
President · Co-founder
Prior career - aviation
Before construction, Connor flew as a commercial-rated private jet pilot, captaining three demanding airframes:
Aviation taught Connor the habit that now defines how ACG runs every project: checklists, preflight discipline, and assuming nothing. Pilots do not guess and they do not improvise - they brief, they verify, and they execute the plan. That is the operating standard he brought into construction.
On May 25, 2017, a crash left him with a diffuse axonal injury, a traumatic brain injury that ended that career. In January 2018 he started at the bottom at Liberty Builder Group, then founded Liberty Impact Windows & Doors with no glazing experience and sold in 2021.
Founder track record
Before ACG, Connor previously founded Liberty Impact Windows & Doors, a Florida impact-glazing company he built from zero and sold in 2021. Year-over-year results:
That trajectory - 25x growth in four years inside one of the most demanding impact-glazing markets in the country - is the proof point. Connor did not learn commercial glass from a textbook; he scaled a Florida impact-window operation from a garage to eight figures and sold in 2021, and he carries that field-earned judgment into every ACG estimate, submittal, and install.
At ACG
Connor runs ACG's day-to-day operations - estimating, GC relationships, project management oversight, and the ESWindows account. He is the direct point of contact for general contractors including DeAngelis Diamond, Proctor, Curran Young, and Rycon.
The aviation background is not window-dressing. It is the reason ACG ships detailed submittals early, flags risk before it bites, and treats every scope the way a captain treats a flight plan - signed off, double-checked, and executed without drama.
Two co-founders. One operating standard.
Owner-level accountability
Every project has a principal-in-charge. No account executive layer, no regional manager buffer. The person you call is the person making the decision.
Preflight discipline
Submittals, shop drawings, and long-lead orders go out early and double-checked. Problems are flagged in the estimate stage, not in the field.
Procore-native operations
Every active job is tracked in Procore in real time - submittals, RFIs, schedules, and closeout. Fewer hands on the file, faster answers than legacy shops.
48-hour bids
Documented scopes get a detailed proposal or budget direction back within 48 hours - priced by the principals, not a trainee estimator.

Questions about ACG leadership, answered.
Who is the CEO of American Commercial Glass?
Rielly Walsh is the Chief Executive Officer and co-founder of American Commercial Glass. She holds 51% majority ownership of the company, which qualifies ACG as a Woman-Owned Business Enterprise (WBE). She studied Concrete Industry Management at Middle Tennessee State University — one of only four U.S. universities offering the CIM degree — and served as lead superintendent for the exterior stoneworks at The Estates at Aqualina in Sunny Isles Beach before joining ACG in 2022.
Who is the president of American Commercial Glass?
Connor Walsh is the President of American Commercial Glass and the qualifier of record for Florida Certified General Contractor license CGC #1531993 (Florida DBPR license lookup, 2026). Before founding ACG, he built Liberty Impact Windows & Doors to over $10M in annual sales in four years and sold in 2021. He was previously a commercial-rated private jet pilot, captaining the Bombardier Challenger 601, Cessna Citation 650, and Gulfstream GIII.
What is the relationship between Rielly Walsh and Connor Walsh?
Rielly Walsh and Connor Walsh are the two co-founders of American Commercial Glass and are married. ACG operates as a family-owned, owner-operated commercial glazing contractor, with Rielly as CEO and majority owner and Connor as President and license qualifier.
Who is the license qualifier for CGC #1531993?
Connor Walsh, President, is the qualifying agent for Florida Certified General Contractor license CGC #1531993 issued by the Florida Department of Business and Professional Regulation. The qualifier holds direct responsibility to the licensing board for the licensee's contracting work; ACG's qualifier is an owner, not a hired third party.
Is American Commercial Glass a woman-owned business?
Yes. American Commercial Glass is a Woman-Owned Business Enterprise (WBE) by ownership because Rielly Walsh, CEO, is the 51% majority owner. WBENC formal certification is in progress as of 2026, and ACG can provide ownership documentation to procurement teams requiring diversity sourcing verification.
What construction standards does ACG leadership work to?
ACG leadership prices and delivers commercial glazing scopes to Florida Building Code 8th Edition (2026) requirements, Miami-Dade Notice of Acceptance (NOA) documentation (Miami-Dade NOA search, 2026), and, where projects require, federal AT/FP standards including UFC 4-010-01 (DoD Antiterrorism via WBDG, 2024) and ASTM F1642 (Airblast test method, ASTM 2022). Both Rielly and Connor are directly involved in scope reviews on projects governed by these references.
How can I contact ACG leadership directly?
Connor Walsh can be reached at connor@acglass.com or (772) 486-7711 (tel:+17724867711) for scope, drawings, and general contractor coordination. Rielly Walsh can be reached at rielly@acglass.com. Both are U.S. citizens and are physically based at the West Palm Beach headquarters, 700 S Rosemary Ave, Suite 204.
How many owner-operators does ACG have?
ACG has two owner-operators — Rielly Walsh, CEO, and Connor Walsh, President — both active on projects rather than sitting in an executive suite. This structure differs from typical Florida glazing subcontractors, which usually operate with a hired qualifier, a rotating sales team, and no owner in the chain of accountability on a given job.
How does ACG's leadership structure compare to a typical glazing subcontractor?
ACG runs on an owner-operator model where the license qualifier and the CEO are both active on projects; a typical Florida glazing subcontractor operates with a hired qualifier and a rotating sales team. The table below summarizes the operating differences relevant to GC prequalification.
| Role | American Commercial Glass | Typical FL glazing subcontractor |
|---|---|---|
| License qualifier | Connor Walsh, President (owner-qualifier) | Hired external qualifier |
| CEO | Rielly Walsh (51% owner; active operator) | Non-owner executive |
| Bid signatory | Owner (Connor Walsh) | Estimator or sales rep |
| WBE ownership | 51% woman-owned (Rielly Walsh) | Non-WBE |
| GC contact continuity | Same owner from bid to closeout | Bid handoff to PM after award |
Where can ACG leadership credentials be verified?
Connor Walsh's Florida CGC #1531993 qualifier status is publicly verifiable at the Florida DBPR license search (myfloridalicense.com, 2026).
