Intro to my blog

Hello. Welcome to DaJH Diagnostics, the future of Swimming Pool and Hot Tub Diagnostic Services.  This is my first attempt at having a Blog so please be patient.  I'm a fast learner and I will try to be consistent. But first, please take a moment and allow me to introduce myself.

My name is John  Harris and I was born in 1969, in Wichita KS, where I still live to this day.  I am proud to be the loving and devoted father of two wonderful children, and the Sole Owner and Service Technician here at DaJH Diagnostics, with over 40 years of experience as an electrical and mechanical Service  Technician in the city of Wichita, KS and surrounding areas.

I've spent my entire working life, almost 40 yrs, as a Service Technician of one sort of another, from Pool Boy to Pool and Spa Technician,  from Appliance Repairman to Industrial Maintenance Technician.  Constantly learning and growing, expanding my knowledge and skill level with each new experience. Hundreds of hours of technical training seminars and on line training sessions. Numerous factory training classes for brands such as Jacuzzi, Sundance, Cal-Spas, Watkins, Caldera, Hot Springs, Pentair, Hayward, Raypak, PCS, Coverstar, and Coverpools, to name a few. Over the years, I have amassed a great deal of knowledge, skill, and wisdom in the fields of Diagnostics and Repair,  especially as it pertains to the Pool and Spa Industry.  Some of that knowledge, I have certainly passed on, training and teaching many individuals along the way but, it takes a special person to be a good, Pool and Spa Technician. I can honestly say, that I am a good, Pool and Spa Technician and I love being a Pool and Spa Technician. It would be a shame to just let all that knowledge slip away, so I promise you here,  and I promise you now, that I will do my utmost, best to keep the knowledge alive and in play for as long as possible by passing it on to you in the form of a Diagnostic Video Service Call with
