Staff Writer

About

In his decades-long career in tech journalism, Dennis has written about nearly every type of hardware and software. He was a founding editor of Ziff Davis’ Computer Select in the 1990s, senior associate editor for PCWorld in the 2000s and creator of CNET’s Workers’ Edge blog in the 2010s. For Forbes Advisor SMB, Dennis covers HR, payroll, payment processing, business formation and many other products and services for small and midsize businesses.

No matter the assignment or topic, two principles guide Dennis’ writing: being fair to vendors and being honest with readers. Business decision makers can trust that they will find an unbiased and thorough evaluation of each product and service Dennis writes about. And in his more than 30 years as a tech writer, Dennis has written about thousands of them: from multifunction printers to ERP solutions.

Dennis knows what’s on the line when a company makes a tech buying decision. Choosing the best option for its unique needs requires timely and complete information, including the pros and cons of various options. When Dennis evaluates a product, he does his best to test it in real-world situations to ensure it functions as advertised.

In addition to working as a senior associate editor for PCWorld and technical editor for the Windows Secrets newsletter, Dennis has owned and operated his own small business, so he’s lived through the ups and downs of starting and managing a company. His career changed trajectory in 2010 when he enrolled in law school. He was sworn into the State Bar of California in 2017 and has provided pro bono legal services for nonprofit organizations since then.

Dennis has dedicated his career to helping people make the most of the technology in their lives. From the earliest PC communications software to today’s phone apps and AI-powered business services, he explains how organizations and individuals can apply digital tools in ways that enhance their professional and personal lives.

Tech vendors deserve a fair shake when their products and services are put to the test, just as readers deserve a comprehensive and honest assessment of the tech tools they rely on. Dennis is committed to helping service providers find the right audience for their products. Whatever tools your company uses, his goal is to help you realize peak value for your investments in technology.
