Strauss left his native Golden Lions last summer following their relegation from Super Rugby after an impromptu phone call from Townsend.
And, with the Warriors sitting proudly at the top of the RaboDirect PRO12, Strauss claims everything has gone according to plan so far.
"Gregor Townsend phoned me out of the blue and I had several extensive talks with him on Skype," Strauss told The Scotsman.
"I liked his enthusiasm and his vision for the club and it is always nice to feel wanted and that is what Glasgow did for me.
"Given the circumstances at the Lions after the franchise was relegated out of Super Rugby, it seemed the right thing to do.
"The facilities here are worldclass. The strength and conditioning was exceptional, the medical staff and everyone involved in the club had such high standards."
