    I have been going here for a while now. Dr. GILLI's staff is amazing!!!! Either text or email and…read moreit is taken care of promptly. Dr. Gilli will tell you like it is. No nonsense. So if you don't like hearing the truth about your care, find another doctor to patronize you.

    Tracy will prescribe multiple drugs and not know side effects. She was condescending from the 1st…read morevisit but I thought it was quirky. In my third visit with her, today, I had to literally walk out and won't be back! I asked other staff if she was just having a bad day. So consistently condescending but today she was actually rude. I asked about side effects of a particular drug she stated no one had ever complained to her before and dismissed my question. Then when I asked her to clarify something she got irritated with me and started with more condescension. If you don't agree with her she will belittle you into thinking you're the one that's wrong rather than explaining like most doctors! No thanks! Update: 04/15/26 - I spoke with Dr Gilli on the phone and it's seems they are somewhat flippant and unapologetic in their attitude towards the situation. I don't feel comfortable with this response that she "always" treats patients with respect after I conveyed the opposite in a professional manner over the phone. This was damage control gone wrong imo. Black box warnings are serious and it's too bad this Dr. doesn't care to make any changes as she is a 25 year employees with the company. He's got her back regardless. I appreciate the call back but it's clear his attitude is just like hers. They don't care.

    I cannot speak to the quality of care provided by the doctor, but my experience with the front…read moreoffice staff was extremely disappointing and unprofessional. I scheduled this appointment months in advance as a new patient and even called a week beforehand to confirm everything. I was told that new patient paperwork had been emailed to me, but I repeatedly explained that I had never received it. I asked multiple times for the paperwork to be resent and even requested it through the patient portal, but the staff refused, stating they were unable to resend the email. The staff stated they had been trying to call me to confirm, but my phone records prove this wrong. Instead, I was told I would need to leave work and physically pick up the paperwork, and that I would have only 30 minutes to get to the office and fill the paperwork out before they closed for the day. They also stated that this was the only day they would accept the paperwork. I found this incredibly unreasonable and inconvenient. To make matters worse, despite having called a full week in advance and making multiple requests for the paperwork to be resent, they informed me they would cancel my appointment because the paperwork had not been completed. This was entirely due to their inability or unwillingness to provide the forms after repeated requests. Most medical offices simply ask new patients to arrive 15-30 minutes early to complete paperwork. Requiring paperwork to be completed a week in advance and then canceling an appointment because forms that were never properly provided were not returned is, in my opinion, excessive and unacceptable. Again, I cannot comment on the doctor, but the front office experience was frustrating, unaccommodating, and far below the level of professionalism I would expect from a medical practice.

    This guy needs to RETIRE NOW. I don't have the time to go into detail, but, he is way past his…read moreprime. My wife and I each had an appointment today, and it was the worst doctor appointment for us both...EVER.
