    Been going to Dr. Susan since 2014. I see only her and one of the PA's who is very nice. I get my…read morereferral with in three day longest 5 days.to a specialist. Which is needed. She is very kind and has gone out of her way to care for my health needs. She extremely busy in this two new offices. So I do not like to wait on hold for 20 mins that's an issue. But not with her it's the staff.

    This place is a joke and a waste of your time. They are extremely difficult to deal with…read more I have been going back and forth with the from office staff for nearly 2 weeks to get the medication THEY prescribed filled. EVERY time they prescribe me a prescription I have to get on the phone with them multiple times to actually GET the medication. They always mess something up. And I've reached out to both the insurance company and the pharmacy and both say the issue in on the dr. office side. I have reached out to Biegel's office atleast 6 times trying to get my medication. The office staff tells me they will leave a message with the provider (because Susan is NEVER EVER In Office. It's been Years and I've NEVER seen her). I had an appointment to discuss my bloodwork. They levels were too low they they upped my dosage. Meaning they prescribed me a new dosage of the same medication I've been taking for decades. BUT it's been 2 weeks since they prescribed it and the pharmacy says they sent the prescription but they have not approved something. I don't know that because I'm NOT a medical professional. BUT I am having to be the middle man between the pharmacy and Biegel's office becuase apparently the pharmacy has informed me that Beigel will not take phone calls directly from the pharmacy. Another inconvience of this office. At this point I should be on the damn payroll because I'm working harder than the Office staff. AS soon as I get a refill on this med I am switching doctors. It's been years if issues with Beigel. I've just been too lazy to do anything about it because I don't need the office often. FUNNY! While writing this review the pharmacy reached out to me to inform me they messaged the Dr. AGAIN to inform them they need to prescribe tablets because my insurance doesn't cover Capusles. I have NEVER had this medication in a capsule to begin with....it's ALWAYS been tablets. SO now again I will reach out to Beigel's office and be the middle man...doing their work for them. Should we take bets on how long until I get my hands on My Medication? P.S. I am now several days without the medication which I informed Dr. Beigel's office days before I ran out. BUT I have to get a blood draw in a week and a half to test my levels and see if the medication needs to be adjusted....BUT now the levels will NOT be accurate anyways. So we've just delayed my Health by atleast a month.

    I highly recommend Dr. Abdelkarim. He is incredibly patient, thorough, and truly cares about his…read morepatients. He stayed committed to my care and continued working with me until my stomach issues were finally resolved. You never feel rushed or like just another patient--he listens, takes your concerns seriously, and treats you like family. I'm so grateful for the level of care and attention I received and would absolutely recommend him to anyone looking for a knowledgeable and compassionate gastroenterologist.

    It's was my first time there on July 17, 2025 I'm praying that my experience here will be pleasant,…read morepositive and healing. I'm scheduled for a colonoscopy- I was told that the soonest they could get me in for the procedure is August 21, 2025 I have called to ask for something sooner but his scheduler said nothing sooner and if pain persists go to the hospital. Honestly this was very unsettling. I had blood work done she also stated that the PA signed off on it so if something was alarming I would have gotten a phone call- this is neither reassurance. Initially to get in with the doctor I called for 5 days looking for a cancellation as recommended by the staff to be seen sooner (no success) some of these reviews are scary . Document Everything. I was also granted a referral for the Doctor but I seen the PA . I'm not sure what the protocol is.

    This is long but worth the read. I've been a patient for over 2 years…read more The receptionist informed me I needed to pay my outstanding balance and office visit copay before seeing the doctor. I had no problem paying the required amount. At this point, the situation took an unexpected turn. When asked if I required a receipt, I indicated that I did, as I always request one due to using my FSA debit card. Upon receiving the receipt, I noticed it only reflected my total amount due and the copay. I subsequently approached the receptionist to request a detailed itemization of my payment. I was informed that it was not possible to provide a receipt for the copay. This response surprised me, as I have not previously encountered a medical office unable to provide the requested documentation for charges. I explained that my FSA administrator requires a detailed receipt outlining each charge for verification purposes. Again, I was told that she couldn't do it. All the while, she was rude and made me feel as though I was bothering her for asking. Then she brings another person into our conversation. She was just as condescending. I explained to her as well, the importance of my needing a detailed receipt and why. I went into further detail, stating to her that if I don't have a detailed receipt of charges, FSA will shut down my card and not allow me to use it for any other doctor appointments nor will I be able to pay for my prescriptions. Both basically ignored my request and I was told, "well hopefully they won't ask and if they do, that will give us time to generate a receipt or you." When I entered room 2 to speak with the doctor, I told the young woman who took my blood pressure that I was very upset--she had likely seen what happened at the front desk. I explained that I needed a receipt for the copay and the reason why. She spoke with her manager and, within two minutes, returned with a separate receipt showing my copay. That was all I wanted, yet the front desk had refused to provide one. Your front desk staff really needs customer service training. Obviously, what I asked for was doable. They just didn't want to do it or take the time to ask someone how. They didn't empathize with me AT ALL when I told them why I needed the receipt and the inconvenience it would cause me if I didn't have it.
