My husband and I have used Richard over the last couple of years. My husband has shoulder pain for being on the computer a lot, and he also suffers with his back. I had pulled muscles in my leg and groin and a bad back that went when I got out the chair. Richard is a lovely man who is 100% reliable. He is very very knowledgeable and has years of experience. It's great because he comes to our house so we don't have to travel. I completely recommend Richard to everyone.
