On the 75th episode of the GreatBase Tennis podcast, Steve Smith and Brandon Flanagan have a conversation with Mark Walpole. He is a tennis coach from Great Britain who has resided in Southern California for over thirty years. As a compliment, we have labeled Mark as a trench pro. He is opposed to the assembly line found at most tennis academies as well as recruiting the kid who can already play.  We are confident that our audience will find Mark's honesty both refreshing and revealing.
