"For me just talking or thinking about this procedure was hard. In my mind I pictured this going totally different, and ill have to say I was way wrong. (Thank God). It was my first procedure, and the hardest part is not eating. The actual Procedure was the easiest part. If God says the same. I'll use Aris Tsiakos, M.D. for my next one in 10 years."

"Very professional and very friendly. The entire experience went very smooth. Well lubricated you could say. The warm blanket and gown were spa like touches (the back of the gown was still a bit drafty though). Everything moved foward very efficiently and yet somehow never felt rushed. Dr. Tsiakos took the time before and after to explain everything and answer all my questions. Start to finish it's obvious this office is very experienced, professional, and really pleasant. I almost look foward to the next visit. Almost."

"All the forms were readily available at the web site. They were easily printed and were quite comprehensive but easy to follow and had very little duplication. The firsts office visit was right on time. The Physician's Assistant got right to the topics and preliminaries. Dr. Tsaikos came in not two minutes behind. He had read my prior charting which goes back 8 years and the latest report 3 years ago. He fully explained the colonoscopy process, its reasons, outcomes, and the plan for any scenario. He had a pre-prepared sheet for the prep and I was immediately scheduled for the procedure. Everyone who talked to me knew exactly what to do, what to say and there was no time wasted. I was not rushed but comprehensively evaluated including the forms i filled out and left at the front desk. Dr. Tsaikos asked relevant medical questions and had my medical history in his hand. Comprehensive; professional; courteous; knowledgeable. TDDC in Plano gets an A+ in my book. Dave"
