I'm Jon Erdmann — 18 years in the trenches of business IT, most recently as CIO of a community bank. Erdella LLC is how I bring that same hands-on judgment to your technology decisions: no reseller kickbacks, no consultantware, just clear recommendations you can act on.

Services
Every engagement ends with a written executive report — findings, prioritized recommendations, and a defensible action plan.
A top-to-bottom evaluation of your current services, network, infrastructure, and daily workflows. You get a prioritized roadmap that reveals redundant spend, security gaps, and quick wins.
A hands-on evaluation of your Microsoft 365 tenant — admin permissions, conditional access, identity hygiene, mail flow, and data protection — mapped against Microsoft's Secure Score and real-world attack patterns.
A practical, non-hype assessment of where AI actually moves the needle for your business — with clear guardrails around data privacy, licensing, and vendor lock-in.
How we work
30-minute working session to scope goals, stakeholders, and constraints.
Read-only tenant & infrastructure review — no disruption to production.
Written findings, prioritized recommendations, and rough cost/effort estimates.
Live walkthrough with your leadership and — optionally — your MSP or internal IT.
About
I started in IT in 2008 fixing broken laptops on a help desk. Since then I've been a technician, a consultant, an IT administrator, and — for nearly eight years — the Chief Information Technology Officer of a Fargo-based community bank, where I was responsible for everything from Active Directory and Microsoft 365 to firewalls, virtualization, and vendor management.
Today I'm the Information Systems Manager at Bravera Bank, and I founded Erdella LLC to bring that same operator-level judgment to businesses that don't have a CIO of their own. Every recommendation I give is one I'd make (or have already made) in a production environment I'm accountable for.
I don't resell software. I don't take vendor kickbacks. I write plain-English reports your leadership team can actually read, and I only take on engagements where I'm confident I can deliver real value.

Why Erdella
Erdella is deliberately small. You work with me directly — not a project manager, not a rotating bench of juniors. That means faster answers, tighter engagements, and no game of telephone between you and the person doing the work.
We don't resell software. Recommendations are based on fit, not margin.
Every engagement produces an executive-ready document you can share with your board.
Clear price for each engagement. No open-ended hourly billing.
NDA-first process. Findings and data are never shared with third parties.
