About

Welcome to the Train My Tools blog, where iPhone users can learn and share useful travel techniques and pro skills.

The mission is to connect iPhone users in Las Vegas, Seoul, and Busan; then enable bilingual collaboration and learning via Apple Intelligence.

My name is Jeff Drothler, and I am a second-generation German American, originally from Harrisburg, PA, USA. My wife is a first-generation Korean American, originally from Busan. We met in Silicon Valley and lived there for fourteen years. Now our home is in Las Vegas, featuring major conventions and trade shows, plus direct flights to Seoul.

My infotech skillset spans the entire Apple ecosystem (hardware, software, and services). I have many years of hands-on experience configuring devices, systems, and networks.
