A.D. Campbell is the publishing name used by Amber Campbell, the writer and creator behind Grit Gear Grind.

A longtime tool and DIY enthusiast, A.D. handles many projects personally—from changing fixtures and installing wired security cameras to gardening, property upkeep, and operating a zero-turn mower. The tool collection continues to grow whenever the budget permits, with cordless tools holding a particularly dangerous amount of appeal.

Outside the workshop and yard, A.D. enjoys traveling,  scuba diving, and other adventures that provide plenty of reasons to research reliable gear and practical solutions.

Not every subject covered on Grit Gear Grind comes from personal testing or hands-on experience. When a topic extends beyond projects A.D. has completed personally, articles are developed using careful research, manufacturer information, established safety guidance, and other reliable sources. The goal is straightforward: provide useful information, explain the tradeoffs honestly, and never pretend that every job should be handled without professional help.
