Face to face? None. I've never met anyone I've worked with or work for at my current gig in person and I am well over three years in on it. There is no point in arguing that face to face time isn't beneficial though. If it feels necessary/feasible/practical to meet your client in person, then do it. If it can be avoided and you work well together despite the distance, then just roll with it.
