Dr. Leong is an efficient easy going professional who gives me good information up front and takes time to listen and answer questions or entertain discussion about his diagnosis. Illinois Eye Institute (eye specialists) are very professional and monitor my medications and eye health very closely.

Dr. King Leong has always been professional and has always shown an active interest in my health. He encourages me when I do as he instructs and gets on my case when I take my health for granted. Although he chastises me, it's never critical or harmful/harshly. He is committed to getting me healthy to live a productive life. Bottom line is that Dr. King Leong cares!

During my visit he stated I may have a brain tumor based on me reporting that I have been smelling a smoky strong scent for several months. Then he ordered ENT and brain cat scans. Very insensitive since there are more conditions related to my symptoms.

Reviewed on November 11, 2018 6:00 PM

I had made a doctor's appointment for suspected BV and when the doctor came in and I told him what was wrong, he seemed completely disinterested and rushed. I could tell that he wanted to hurry up and be done with me. He immediately prescribed 2 medications (one I didn't feel like I needed) upon talking to him for not even 1 minute. I asked him if he would do an exam on me and he essentially said that he didn't need to because my issue was something I had had before. When he told me my prescription (metronidazole), I told him that I had never needed to take the second medication (for yeast infection) in the past and he shrugged as if to say "whatever". I had to stop him from walking out of the room to ask what form my medication would be in, pill or gel. It was only then that he asked for my preference. Because he did not want to listen to me or examine me, I essentially had to diagnose myself. It was an extremely unpleasant experience. I plan to never be that egregiously ambivalent to the concerns of my patients in the future.

I was not pleased at all with my visit with Dr.Leong. The appointment was very rushed; I was only with Dr. Leong for no more than 5 minuets. I scheduled an appointment for a yearly exam and to establish care. I assumed that I would be getting a full physical. Nor did Dr. Leong ask any questions pertaining to my health. I'm actually really disappointed because I'm very familiar with Advocate Heath care and have always a received great care. Now I have to find a new provider because I still have concerns regarding my health.

From the start there were problems: 1 - nobody called me to inform me that my appointment had to be rescheduled so I showed up after leaving work early only to have to reschedule it for another day, which could have been done over the phone.2 - Dr. Leong was the worst PCP I've ever had. He hardly spoke to me about any of my general health or concerns I may have had. He did not seem to listen to what I was telling him. He did not ask at all about my past medical history or family history. He only used the stethoscope to check my lungs, but literally did nothing else to assess my physical wellness. He was a bit rude when he asked "why are you here?" followed by "why would you move to chicago?" after explaining I just moved here for a job. Overall he was very unprofessional, I wanted to discuss some health concerns I had but all he did was recommend me to a surgeon without explaining why or what for. And I've wasted my annual physical for the year despite leaving with more questions than answers about my physical. I will NOT be coming back next year.
