Finally, a Responsive Managed IT Partner for St. Louis & Chicago Businesses. You deserve better than voicemail hell and endless ticket queues. We pick up the phone live—24/7.
It’s the most common complaint we hear from new clients: "Our old IT guy takes days to call back." In today’s fast-paced digital economy, you cannot afford to wait. A server crash or a network outage isn't just an inconvenience—it's a direct hit to your revenue and reputation.
We are a second-generation, family-owned business founded in 1984. We understand that behind every support ticket is a person trying to do their job. When you call us, you speak to a live, local expert who can start solving your problem immediately—often within minutes.
No automated phone mazes. Real people, real answers.

We stop problems before they disrupt your business.
A commitment to excellence that has earned us a spot on the Inc. 5000 list.
At Computerease, we understand how important trust, consistency, and a personal touch are in choosing an IT partner—because we’ve built our business that way from day one. Our story started back in 1984 when Ike Haislar founded Computerease with a mission to help small businesses make sense of rapidly changing technology.
Today, Ryan Haislar, CISSP, carries that same mission forward—adding cutting-edge cybersecurity expertise while keeping that family-first mindset. Whether you’re an office manager looking for reliable support or an IT director needing a trustworthy co-managed partner, our commitment to integrity, transparency, and long-term relationships is built for you.
“You deserve an IT partner who’s fast, dependable, and delivers old-fashioned customer service – every time.”

We don't believe in guessing games. We have honed a proven process over 40 years to ensure every client receives consistent, high-quality results.
We start by listening. We conduct a deep-dive audit of your current network, security posture, and business goals. We identify hidden risks and opportunities for efficiency.
We don't just fix what's broken; we plan for where you're going. We create a 3-year technology roadmap that aligns your IT budget with your business growth objectives.
Our dedicated onboarding team ensures a smooth transition. We document your network, deploy our management tools, and stabilize your environment to eliminate recurring issues immediately.
This is where the magic happens. We monitor your systems 24/7, patch vulnerabilities, and optimize performance. We meet with you quarterly to review progress and adjust strategies.
In a co-managed model, cybersecurity is where a partnership truly shines. Many internal IT teams are brilliant generalists but may lack the niche, up-to-the-minute expertise of a dedicated security professional. Our CISSP-led team doesn't just install software; we provide strategic guidance.

NATIONWIDE SERVICETechnology is complex, but your relationship with your IT provider shouldn't be. We simplify the complex through strategic leadership and proactive care.
Missed opportunities, damaged reputation, and data recovery costs. Studies show a single hour of downtime can cost small businesses thousands of dollars.
Hackers have industrialized cybercrime using automated bots 24/7. They scan for any open door to encrypt your files and demand payment.
The traditional office is changing. Cloud computing makes it possible to scale up or down and work from anywhere in the world.
Most small businesses cannot afford a full-time CIO. Our Virtual CIO service bridges this gap to translate goals into tech requirements.
Hiring for specialized IT skills is expensive and time-consuming. Building an internal 24/7 SOC is often financially unfeasible for most organizations. A co-managed partnership gives you immediate access to a deep bench of talent on a flexible, operational expense basis.
Our co-managed model provides access to all this expertise and more for a predictable monthly fee, allowing you to scale your capabilities up or down as projects and business needs change.
Don't let another day go by dealing with slow computers, unresponsive support, or the fear of a cyber attack. Join the 200+ businesses in St. Louis and Chicago that trust Computerease to power their success.
