About Us
Three Decades of Putting Clients First
Tech Collaborators was built on a simple belief: businesses deserve unbiased technology advice from people who have actually done the work. For 30+ years, that's exactly what we've delivered.
Our Story
We Listen. We Match. We Deliver.
With many years of experience in the telecom and I.T. industry, we are able to marry clients' essential telecom and IT needs with our wide array of solutions from many vendors.
We started selling for a regional carrier, then for MCI and eventually working for Lumen in the Enterprise level helping multi-location, multi-national accounts. In between, Mark Calonder, the president bought a Samsung certified Interconnect in Chicago. There, his firm was one of the 1st companies in the city to successfully sell and install VoIP systems. All along, being 100% consultative drove the successes. Key to the process: uncovering pain points, budgets, and goals before ever recommending any solution.
That approach hasn't changed. What has changed is the breadth of our portfolio. Today we work with 50+ technology partners across voice, connectivity, cloud, and managed services — which means we can always find the right fit, not just the most convenient one.

What We Stand For
Our Values
Integrity Over Commission
We are compensated by vendors, but our loyalty is to you. We will never recommend a solution that doesn't genuinely fit your needs — even if it pays us more.
Accountability
One point of contact. One number to call. We own the outcome from first conversation to final delivery — and we stay available long after the contract is signed.
Expertise You Can Trust
Three decades in the field means we've navigated every technology shift — from analog PBX to cloud-native UCaaS. We bring that depth to every engagement.
Simplicity
Telecom and IT can be overwhelming. Our job is to cut through the noise, translate the jargon, and give you a clear path forward.
What Vendor-Agnostic Really Means
We Work for You — Not the Vendor
Most technology resellers have preferred vendors — the ones that pay the highest commissions. We don't work that way. Our portfolio spans 50+ carriers and technology providers, and our recommendation is always based on what's right for your business: your size, your budget, your workflow, and your growth plans.
That independence is our most valuable asset — and yours.
