By every genre, I am going to assume that you mean he does portraits, weddings, nature, wildlife , architectural, etc. My initial question would be - is he for real? I think, sometimes, that photography is a bit like medicine - you have generalists and you have specialists and who make the most money(?). I am not a pro, and I have been doing wildlife, nature and landscape photography as a serious hobby for more years than I care to think about and there is so much more for me to learn - I don't even go anywhere near photography that has anything to do with having people in pictures, unless it is travel snapshots of my wife in front of our safari jeep. He must have access to a lot of equipment(?) to do every type of genre...
If you look at the very good pros who are recognized for what they do, they have one thing in common, they specialize in one specific genre and do it very, very well. Even if you look at the great masters (my opinion) such as Adams (landscapes), Yousuf Karsh (portraits), Breton (candid street photography), you find that they all specialize in very specific aspects of photography, even to the point of folks like Bill Doster who specializes in photographing water sports, wakeboarding, water skiing, etc, and Michael Clark who specializes in action and higher risk sports - mountain biking, mountain climbing...and then you look at those who today specialize in things like landscapes and nature, Alain Briot, Galen Rowell, George Lepp, and as you are from my part of the world, look at the works of Edward Burtynsky (old master), Malak Karsh (Yousuf's brother who was a very good photographer in his own right), Darwin Wiggett, Mike Grandmaison, John Marriott, and Ethan Meleg, to name a few. You can also have a look here for more "specialists" -

Personally, I fail to see how one photographer can do all genres and be any good at any of them...sort of a "jack of all trades and master of none" kind of thing. In my opinion, it is important to pick one area and get very good at it, particularly if you are going to try and sell your images. Anyway, my 0.02¢ FWIW.
