PSG Tees started back in 2006 when I designed and screen printed all the shirts in my garage. I have been in the sleep diagnostic field for over 31 years. I was a sleep tech, worked the third shift, used the pen and ink recording systems, did research, managed several labs and currently I am a sales rep. I am also an artist and learned screen printing for fun. I designed shirts based on my experiences and sold them at sleep conferences in the Boston area. These shirts are great to wear on the night shift, as a comfy nightshirt or while working out. I was often asked if I had a website. The PSG Tees Zazzle Store allows me the ability to offer a website to offer these shirts along with mouse pads, pins, coffee mugs and many other products. Thank you for looking at my designs at PSG Tees. Sleep Well!
