Dr Cohen has been exceptional throughout my diagnosis and treatment for Cushing's syndrome. After years of unexplained symptoms including weight gain, fatigue, nocturia, muscle weakness and other health issues, he quickly identified the underlying cause and arranged the necessary investigations and treatment. He has always taken the time to explain results clearly, answer questions and ensure I understood the next steps. His proactive approach has made a huge difference, and I finally feel that I am receiving the care needed to get my health back on track. I would highly recommend Dr Cohen to anyone looking for a knowledgeable, thorough and caring endocrinologist.
