Dr Theo is very nice, extremely patient and makes you feel at complete ease. He listens to you and your views before giving his professional opinion, which I believe is very important for patients to be heard too. Nothing feels rushed - Dr Theo takes the time to explain & communicate effectively.

The practice Manager Kathryn is absolutely fantastic. Always available on the phone, always replies to emails almost immediately and I don’t know how she manages that. Frankly when I call up with regards to anything, be it an appointment, a message for the doctor to call me or whatever else it’s just done, and done with extreme charm and kindness.

Dr Michael Criswell has looked after my husband and I for many years. His support and expertise has been unfailing throughout. Theo is now continuing that tradition. Michael and Theo are supported by the wonderful Kathryn and Gilda who show the same dedication and personal touch. We are incredibly lucky to be so very well looked after by the Criswell Practice. It is head and shoulders above any practice I have ever known.
