Well I've never heard of him on these boards - unless I've missed his name mentioned. I would speak to people that have used him first. I chose Dr Rogers as lots of people were making favourable comments about their experience with him.
I just wouldn't take any risks on such a serious step. You've got to know that Dr Westwood's credentials are good. Don't leave it to chance - you must have good reason to choose him - you've got to live with the results.
All the best
