Years later whilst settled in Oregon, Adams performed various plays for the Oregon Shakespeare Festival.
It was whilst acting in Taming of the Shrew that Adams was spotted by an NBC executive, which led to roles in Frasier, City of Angels, and, like Bones co-star TJ Thyne, in Chuck Norris's Walker, Texas Ranger.
Jonathan Adams was a regular on The American Embassy and also acted as Henry Walker in American Dreams.
