About SOSNA
As a lawyer-turned-immigrant-turned martial arts instructor who needed money to buy food, founder Andrei Sosnovsky took on a construction job in 1996 that — thanks to his determination and drive — blossomed into his own renovation business. Now, after more than 20 years in the renovation industry, SOSNA is a successful (and growing) award-winning residential renovation company. While he may not practise Sambo regularly these days, it’s not hard to find the strict discipline of the martial art as the backbone of the SOSNA process.
