Robert Sweat

My career in private investigation began after working for an attorney, which naturally led me to this field. I passed all state licensing exams on the first try, a testament to how innately this work suited me. I believe I just have an inquiring mind. While the work demands hard work and dedication, I genuinely love solving problems. When I'm given a task, I'm as committed as my client to getting to the bottom of it, and I always strive for a positive outcome.
