Dr. Mar has great expertise as a physician, and is just as noteworthy in his interactions with others. He takes the time to understand each of his patients and treats them as equals. He is very accommodating to the unique needs of each patient and each family. He is brilliant, considerate, and passionate about his service for others. I could not recommend him highly enough.

Very understanding and willing to help me make sense of my thoughts and feelings. Great analogies with situations I put myself in which help give me an outside perspective when I am so blind to my own reality at times.
