I’ve just met with Dr. Sana once and will soon have a procedure. He wasn’t in a rush to leave the room as doctors sometimes seem, he answered all my questions, was very informative, friendly and had a good sense of humor. Nice man.

Dr M. Sana was very proficient, professional and thorough and also had great bedside manner. He listened to my concerns and answered my questions. I would recommend him to anyone with acute or chronic conditions. Spring ‘23 I first saw Dr Sana after 7 yrs of chronic diarrhea and gut inflammation. No one could help until Dr Sana, for whom I am eternally grateful. This time, labs ordered by Dr Sana revealed undiagnosed Salmonella. Previous med interventions only tested for flu which I didn’t have. SMH. I had severe diarrhea and gut inflammation. Dr. M Sana is top notch. So knowledgeable, thorough and excellent in his service provision. He is kind, compassionate and listens. He also has a good sense of humor- a good soul. I will continue to travel almost 2 hrs to see him. He is more than well worth it. Chef kiss.
