The reviews about the unprofessionalism of this place are dead on. Like others, we were attracted to them as experts who could offer more than basic lifestyle modifications for our teenage daughter with POTS and EDS. Her mother also has POTS and saw Dr. Abdallah (the husband) who got her on a good medication mix. But trying to get our daughter treated there has been a nightmare. Like the reviews from 1-2 years ago, they would continually cancel appointments and rebook us for 6 months out, then cancel again. No explanations f... read more

This review is for Dr Abdala at CHI: Terrible admin and scheduling. Our first appt was cancelled two weeks ahead of time but we were told we needed to come in the following day (i.e. "told" not "asked.") -- That didn't work for us, so we rescheduled to this morning at 9am. I have multiple texts, voicemails, etc confirming the 9am time. At 8am, I get a text that the appt has been moved to 10:30am with no explanation, apology, or "request" -- just "your appt is at 10:30am."

Then her symptoms worsened and they tried an additional drugs that made her worse and then a 2nd additional drug thay made her even worse than that. I tried calling to see th... read more

My appointment was less than a week away and I was JUST NOTIFIED they now use a “concierge medicine model” with an annual fee of $5,000. I promptly canceled my appointment. Completely unprofessional to bait and switch your patients after they wait months to be seen.

Dr. Hasan Abdallah and Hala Abdallah have compassion and curiosity. They listen. The care I've received with them is significantly different from what other POTS doctors/Clinics are doing. Why is that? They dig into the cause. They run lots of tests. For me those tests led them to a neurosurgeonwho was able to give me answers. Now I can focus on fixing the real issues and not just manage. This year I finally move on the next step of this journey. I have a direction and that is becauseof these doctors and their dedicated work... read more
