Excellent knowledge on most aspects of primary care. Will spend as much time with you as you need, which can lead to you having to wait beyond your appointment time to see him, but that is the cost of him being willing to spend more than the standard "15 minutes" that some docs will insist on. Explains his reasoning, diagnosis and treatment very well. Have had him as my family doctor for going on 23 years - since I was born and have found him to be easily one of the best doctors I've had the pleasure to see (and I've seen a fair few in my time!).
