A Little Bit More Personal….

I grew up on a small farm in Southeastern Minnesota, and my first “real job,” at the age of 14, was as a busboy at a well-known 4-star restaurant and bar(s) in a nearby city. Yes, I was underage – but I knew somebody.

Have you ever spent a winter in Minnesota? I spent 17 there. Two days after high school graduation, I was on a plane heading to San Diego, California for Marine Corps bootcamp.

I wasn’t a grunt. I worked in a support position for an Artillery Regiment. I maintained records, payroll, and other stuff, and took care of the administrative needs for those men and women who were doing the real work in the Corps. It was a great experience with access to sensitive information, and I maintained a Top Secret clearance. Great job, and I really enjoyed my time in the Corps.

Immediately after my three year enlistment ended (Honorably Discharged as a Sergeant E-5), I remained in Southern California (except for a couple years back in Minnesota – what was I thinking?), and spent the next ten years or so managing restaurants and nightclubs – and did a whole lot of surfing and playing 2-man basketball up and down the coast. What a great time.

It was at this time I decided that working for someone else just wasn’t cutting it – I really wanted my own business so I could call the shots. Thus, my Judgment Recovery and Process Service Businesses were born. Next up was the Private Investigator License. The rest is history.

I have a Bachelor’s Degree in Business. I design and build all of my websites as well as write all of the content for my blog on this site and others.

You’re trying to find someone. You need a very discreet Private Investigation. That’s what we do. For a little more detail on how we go about this, let’s get going and find your subject.

I love what I do, and am currently a member of the below organizations:
