What impressed me most was how thoroughly he addressed my concerns - especially regarding an elevated test result. He took the time to explain what it meant in simple, understandable terms and offered an alternative approach to help manage the issue, which made me feel reassured and supported. He answered all of my questions patiently and never made me feel rushed. I truly appreciate his thoughtful, compassionate, and informative care.
