Pete22,
One of the cardinal rules to choosing a physician for the hair transplant procedure is that the practive should be solely focussed on hair transplant, not other things. In addition be able to view patients on the web and meet in person to discuss the procedure!!!
One of the best clinics in the world is in Vancouver, Hasson and Wong, do yourself a service and check out their site, they are more money but money should not be the deciding factors. They are world known and they have proven large megasessions are very achievable.
The other websites on Hair loss have additional doctors in your area for you to check out.
GOod luck
