I consult Dr Mark Cohen recently as an Endocrinologist for low magnesium which rather not a common but caused me lots of problem. I had forwarded current blood other results before only few days before. I was so impressed Mark was already understanding my illness when I saw him. He was very pleasant , courteous a mannerly in his listening patiently. I felt very comfortable and assured of his fully understand my problem. He explained the cause and treatment immediately. He ordered the necessary tests and referred me to immediate l treatment. He phone me back with result after arrangements and results are few days. I feel full confidence in him and glad I had chosen him in the first instance.

Dr Cohen was very welcoming during my visit, exceptionally thorough from start to finish. He was focused on finding the root cause and keen to explore further upon receipt of the initial tests. He provided a service which made me feel his investment in me as a patient.
