I founded Pat's Pest & Repair after several years in the pest and wildlife control business, and several more years diagnosing, repairing, and providing maintenance for cars, electronics, and appliances (among other things).  I learned a lot about how technicians and businesses typically approach solving problems.  Out of this, plus my personal experience and studies, I have developed a refined approach towards isolating, diagnosing, and solving problems with a strong consideration for the events and/or 'systematic imbalance' that causes them.
