Built in St. Louis. Built for Business Owners Like You.
Drake Service Partners is a St. Louis-based commercial MEP and fire suppression contractor and partnership platform founded by Mark Steiniger and headquartered in O'Fallon, MO. Mark is responsible for driving the company's strategic vision, operational excellence, and continued growth across Missouri and Illinois.
He leads the execution of the Drake Service Partners vision — focused on partnership, standardization, excellence, and building a culture rooted in trust, accountability, and ownership. The Steiniger family has deep roots in the Missouri construction industry through Kuesel, and Mark brings that same commitment to quality, integrity, and people-first leadership to Drake Service Partners.
Become the Most Trusted MEP Platform in the Midwest
Elevate Local Trade Businesses
We partner with strong St. Louis and Missouri MEP, fire suppression, HVAC, electrical, and plumbing companies — not dismantle them. Our goal is to lift capable local shops onto a platform with bigger resources, not erase their identity.
Deliver Single-Source MEP
Building owners and general contractors in St. Louis deserve one accountable partner for mechanical, electrical, and plumbing. We are building the integrated MEP team the Midwest market has been missing.
Preserve Jobs & Craftsmanship
Too many good trade businesses are stripped for parts by outside buyers. We keep technicians, project managers, and field crews in their roles, protecting the craftsmanship that keeps Missouri facilities running.
Create Real Owner Exits
For founders who have spent decades building something real, we offer a partnership path with equity upside — not a cash-out-and-disappear deal. You stay connected to the success of what you built.
A Missouri-First Growth Strategy
Our plan is straightforward: identify the best commercial MEP, fire suppression, HVAC, electrical, and plumbing operators across Missouri and Southern Illinois, bring them under one shared platform, and give every partner better tools without forcing a re-brand or culture transplant.
We are starting in the St. Louis metro — O'Fallon, St. Charles, Chesterfield, Wentzville, and across the Missouri-Illinois border region — because this is where we live and where our relationships run deepest. From there, we expand intentionally into Kansas City, Springfield, Columbia, and beyond.
Partner with Proven Local Operators
We target Missouri MEP, fire suppression, and trade businesses with solid reputations, strong safety records, and owners ready for their next chapter — but not ready to walk away entirely.
Integrate Back-Office & Safety Systems
Every partner gets shared HR, marketing, estimating, vendor relationships, and documented safety programs — the infrastructure small shops rarely have bandwidth to build.
Win Larger Commercial Projects Together
As a combined platform, we qualify for bigger design-build, multi-trade, and facilities contracts across Missouri and Illinois that individual shops cannot carry alone.
Reinvest in People & Regional Expansion
Profits go back into training, equipment, and opening doors in new Missouri markets — Kansas City, Springfield, Columbia, and Jefferson City.
Why St. Louis? Why Missouri?
St. Louis is one of the most active commercial construction corridors in the Midwest, with a constant pipeline of healthcare, industrial, education, and multi-family projects. Yet the MEP and fire suppression trades here are still fragmented — dozens of solid HVAC, electrical, plumbing, and sprinkler shops operating independently without the scale to compete for the largest regional contracts.
Missouri also has a generational transition problem. Thousands of trade business owners are nearing retirement without a real succession plan. Their kids chose different paths. Private equity buyers want to flip them in three years. Mark Steiniger and the Drake team offer something different: a local partner with a proven family legacy in Missouri construction through Kuesel, who knows the market, respects the legacy, and shares the upside.
No Succession Plan? You Are Not Alone.
If you own an HVAC, electrical, plumbing, fire suppression, or mechanical contracting business in Missouri and you do not have a clear path to retirement, you are in the majority. Most trade business owners in St. Louis, St. Charles, and across the state are facing the same question: what happens to the company I built when I am ready to step back?
Mark Steiniger understands this firsthand. As part of a family that has built and operated successful Missouri construction businesses for decades, he knows what it means to care about your people, your reputation, and your legacy. Under his leadership, Drake Service Partners is built on a family-first approach — one that delivers tremendous value to employees and clients while giving owners a path forward they can feel good about.
The options most owners consider:
- ×Sell to a competitor who may dismantle your brand and lay off your team
- ×Pass the business to family who may not want it or are not ready to run it
- ×Sell to private equity and watch your culture disappear in 36 months
- ×Gradually wind down, leaving employees and customers without a home
What a Drake partnership looks like:
- +You retain meaningful equity and participate in the combined platform's growth
- +Your team keeps their jobs, benefits, and day-to-day leadership structure
- +Your brand stays in place until the timing is right for a transition
- +You gain back-office support, marketing reach, and access to bigger commercial projects
- +You work with Mark Steiniger — a local partner who knows St. Louis and Missouri, not a distant fund
You do not have to choose between a bad exit and working forever. There is a third path — one that honors what you built, protects your people, and gives you a real stake in the next chapter. If you are a Missouri MEP, fire suppression, HVAC, electrical, or plumbing business owner exploring your options, we would welcome a confidential conversation.
