Dr. Zelcer was cardiologist on call at Delray Medical when I went to Emergency Room. My test were sent to him by Er doctor. He came in immediately on a Friday night and performed a life saving procedure. His aftercare was amazing and he truly stuck up for his patient ( me) when another doctor started to do something wrong! Dr. Zelcer was amazing to my husband and son and explained everything to us with perfect analogies instead of just big medical words! His personality is serious about your health but also has some great jokes. I have complete trust in him to take care of my heart and everything involved with it! I and my family will be forever grateful he was in call that night.

Dr. Zelcer is AMAZING He is the best Dr. I have ever had for my Husband he saved his life not once but twice. He is a wonderful human being and a SUPERB doctor. I just love him more and more! I am truly grateful for his excellent skills

Excellent medical professional. Progressive and non alarmist.I highly recommend him and his staff .

The doctor takes care of my husband and all of his friends.We are extremely happy with our care, and the attention we get. He has been easy to confide in, and is loved by everyone we send.

DR ZELCER IS A TREMENDOUS PERSON . HE WAS MY MOMS DOCTOR FOR 7 YEARS. OUR FAMILY THINKS THE WORLD OF HIM.

Superb office.Extremely knowledgeable doctor. Takes time to explain everything in detail.

No bedside manner, no follow up, treats employees horribly, making patients uncomfortable. Also treats family of patients with arrogance and dismissive attitude. Records charting in the hallways, no regard for privacy laws. Although seemingly extremely intelligent, he is opinionated, stubborn and just plain rude. I believe he is his own worst enemy. Avoid if possible.

We cannot comment on the doctors.When we called to schedule an appointment the woman who answered the phone was so rude, uncaring, abrupt, and impatient, that we opted for a different office. We asked the woman her name and she identified herself as Miriam. Such a disappointment that Miriam, working in a medical office, showed no kindness, courtesy, patience, or caring for a potential patient.
