After realising his childhood ambition to become a zoo vet wasn't for him, Mark set out on the journey to specialise in neurology. He talks about the value of seeing general practice before specialising and how failure can be a positive if you seek to learn from it. He sets out his views on the problems with corporate practices focusing too much on spend per visit, and the value of experience adding to client satisfaction. He talks about how this experience can help with choosing the most valuable tests to run, and what to do with results - especially if they come back normal.
