I had a very good experience with Dr Lacy at my first consultation. She was calm (much needed in a stressful health situation), knowledgable, patient and explained every part of the process in great detail. She also went out of her way to accommodate for my next appointment later this week to have a procedure done. I felt reassured, understood and professionally evaluated.

My visit to see Dr Katie Lacy, who diagnosed Lyme's Disease that others had failed to recognise for months, was not only thorough, she arranged a comprehensive series of tests with the appropriate specialists. She was patient, attentive, caring and reassuring. I had seen Dr Lacy for skin Melanoma 3 years previously. I am extremely grateful to her and have no hesitation in recommending her to any future patients
