LOL Greg...
Yes he can truss the roof but this would be the most expensive ($$) option.
The least expensive IMO would be to create a flitch plate beam using the existing 2x10 beam thats there. Basically just add the 1/2" thick steel plates and additional members as calculated. I believe the end post lands in between the 2 garage doors and not over the header that would be on say 1 large garage door. If this is true he would have to open up both end walls and add a 2x4 to each side of what should be a double 2x4 post there already. then he would have to temp. support the clg joists and build the flitch plate beam. Lastly he can then remove the center post in question once completed.
This again IMO would be the easiest and least expensive option.
