You should pass me the details of your doctor - I always spend a little time at the end of a project going through and trying to eliminate vias if I can as I see everyone of them as a potential failure point - and it's very satisfying to re-run the drill report and see the hole count drop!

Mind you I'm not obsessive though.  I worked with one relatively inexperienced PCB designer once who spent a whole week designing a power and deflection PCB for a televison and managed to do it all without any vias or wire jumpers.  Unfortunately his design would never have worked with segregation between the primary and secondary sides of the transformer and 0.3 mm traces carrying high voltages and currents!
