Excellent cardiologist.
Great bedside manner!!
He was terrific! I made an appointment to see him in 6 months.
Excellent. Dr. Tumarkin listened to me very attentively about my cardio background. He offered a non-invasive way to temper my breathlessness, before going for an invasive procedure. An excellent idea.
Great doctor!
Personable and professional.
Dr. Tumarkin is a highly intelligent and caring Cardiologist. I would highly recommend him. You'd be lucky to have such an excellent doctor.
I was (luckily) assigned Dr. Tumarkin since Dr. Sharma retired. He was professional, kind, knowledgeable and I am glad I have been assigned to him. I look forward to seeing him again.
Ethan seemed to know his stuff and I feel like he listened and gave good guidance.
He gave me a renewed confidence, in my healing journey. He seemed to genuinely care, and took my concerns very seriously. Thank you very much
Dr Tumarkin is highly skilled in his field. Excellent cardiologist. I've never had a doctor spend the amount of time he did in following up from my 10 day Univ Hospital stay. In reference to my heart failure and ckd. When I left the appointment I was confident of what my part is in caring for myself in the future. If my daily results at home go sideways I have access to contacting him for the next part of the plan. I felt secure in my path of getting better. I highly recommend Dr Tumarkin.
Incredibly knowledgeable, professional and engaging.
Really appreciated his approach, knowledge and willingness to explain things. It was a great experience. Thank you for having such wonderful doctors.
Dr. Tumarkin provided a relaxing, reassuring visit. He paid attention to detail and communicated in an empathetic way.That was appreciated.
Maximum respect
He explained the procedure I will have well. Respectful and understanding
