Our Journey
Founded in Southern California
Tom Hermstad and John Dankha founded HD Tech to bring enterprise-level IT capabilities to small and mid-sized businesses — at cost-effective pricing — to reduce risk and enhance productivity.
Growing with Our Clients
Expanded managed IT services across Los Angeles, Orange County, the Inland Empire, and San Diego. Built long-term partnerships — some of which continue 20+ years later.
The Cybersecurity Shift
Real-world experience with cyber attacks drove home that prevention alone isn't enough. Businesses lose billions each year, and most fail within a year of a breach. We shifted focus toward cyber preparedness.

How We Think About Cybersecurity
Experience with real-world cyber attacks taught us that prevention alone isn't enough. We design systems to withstand, detect, and recover.
