My son has been under Prof Lack care for a number of years. Prof Lack is always calm and reassuring, we never feel rushed and leave feeling positive and knowledgeable. The new ACE clinic is brilliant, the staff welcoming and it’s great that all the allergy services needed are all in one place. Couldn’t recommend Prof Lack and the team at ACE more.
