The doctor and staff were very friendly and professional . The doctor took time to examine
March 27, 2026Anthony N.Verified patient
My experience from my first visit to this doctor's office was exceptional, from the receptionist to the lab tech, everyone treated me with respect, the way every patients will want to be treated when they go to see their medical providers.
I was warmly welcomed by the doctor. who showed impeccable bedside manners. He was very attentive to details, and informed me important findings from lab results handed over to the receptionist upon my arrival.
Left the place very hopeful that I am in good hands with one of the best doctors in this field. I highly recommend Dr Samuel Agahiu.

I am very particular about who I select, being severely undeserved by medical providers in the past. All the great reviews I read on Dr. Samuel Agahiu was my very exact lived experience. I felt like I was speaking to a family member. He was thorough, patient, kind, treated me with the utmost respect, professionalism, compassionate and understanding. He listened to me go on on. He put me at ease the moment he stepped into the room. I'm so happy to have found him. Also his team was so warm and welcoming. I truly felt like I exhaled the moment I said good morning to the lovely human at the front desk. I can't speak highly enough of my experience. Totally top tier all around!!!

August 12, 2025Boguslaw K.Verified patient
Dr Zelkowitz was great at explaining test results. He took the time to hear our concerns with my mother’s reason for seeking a visit. Can say enough about him. He is a very good doctor.

I am beyond pleased with the exceptional care I received from Dr. Zelkowitz. From the moment I arrived, I was impressed by how immaculate the office was and how friendly and welcoming the entire staff made me feel.
Dr. Zelkowitz demonstrated remarkable professionalism, compassion, and patience throughout my visit. After dealing with hematuria for over five years, I was finally referred to his care, and I am truly grateful. He took the time to thoroughly explain the potential causes of my condition, discuss diagnostic options, and outline a clear treatment plan — all in a way that was easy to understand and reassuring.
This medical practice sets a high standard for patient care. My overall experience was outstanding, and I would highly recommend Dr. Zelkowitz to anyone seeking an exceptional kidney specialist.
