Dr. Semyon Kostko, MD

Outstanding practice. Cordial, efficient, very approachable staff and techs, Viktor and Julian, along with affinity driven seasoned, brilliant, outstanding Cardiologists. Currently see outstanding Dr. Vilkas, at this office on Wednesdays. He speaks English, Russian, Hebrew and undoubtedly other languages. The office works very cohesively together with a terrific staff. My parents, now long gone, would've each been overjoyed to be their patient. Sincerely, you cannot go wrong,being a patient here. Speaking for myself: The care is terrific.

This office has very rude customer service. They book appointments and then change the time without informing the patient. It’s unprofessional and shows no respect. I’m only coming because of Dr. Gregorian. but I would never come back to this office because of the staff, the front desk really needs additional training on how to communicate with clients!

The system is outdated, there’s no app for information, and it takes a week to hear back from the doctor. Reception is rude and unfriendly. Poor service — no wonder they’re losing patients.

This is the worst medical office. Dr. Kostko is great but the administrative staff is terrible. I called the office several times to get a refill for my blood pressure medication, but the front desk said the doctor could only send if the pharmacy sent them a request. I called the pharmacy, they said they had already sent a request twice. I've been off medication for three days. My blood pressure is 160/104, but no one seems to care. I usually don't write reviews, but I decided to do this time.

It is the worst medical office I know. I usually don't leave reviews, but this time I had to. Dr. Kostko kicked out my parents who are in their seventies from the office when they came to their scheduled appointment time for IV infusion, because his nurse didn’t show up, and he didn’t even want to speak to my mom same day to follow up after her hospitalization because she came one day early before her quarantine was suppose to end. He screamed at my mom calling her names. Another very important thing is when they do their blood tests, they must come to the office again, just to hear from him that everything came back normal. He will never do it over the phone, since he is so desperate in billing clients insurances multiple times for no reason. But when we actually get those results on hand, I would see so many abnormalities in their results. Also, there is a so called manager Eduard Fuzaylov, known as a psychologist. It doesn't even seem that he is licensed in anything. He is beyond arrogant, rude, and not educated what so ever. I don't even want to waste my time talking about the front desk staff. They are all USELESS.

Zero stars of I could give Receptionist staff (HORRIBLE/ UNPROFESSIONAL. ) ON PHONES TEXTING/. Dr kostko was a pleasant surprise. Also the medical assistant fyi shes new to the staff and In take nurse were nice ......

The doctor treats me ok but the problem i have is that I have a problem so I had a agency called to get a script approved by the doctor. The agency told me it was denied by his office manager that I had problems with prior. The doctor wasn't at the office the staff look and knew that I have a medical issue based on the medication the Dr. Prescribed and the manager still told them no. First the office manager is not my doctor to be making calls that he now's nothing about. I'm very disappointed with how they handled a script that I needed to be approved so that the agency could send me supplies on a monthly basis .

Caring, like the doctors of the past, went over every detail of my report. Fought with the insurance to get my approval. I can't be thankful enough!
