He is the best I have ever seen doctor in my life that why he has a lot patients.

Despite moving to a new state, I have still kept Dr. Seng Leong, as my provider. Dr. Leong is an excellent, top-tier provider who listens to his patients, understands them, spends quality time with them to perform a thorough assessment and follows up with a treatment plan to ensure his patients' well - being. Moreover, he is prompt to respond to messages via the app or missed phone calls, and he is professional, polite and courteous. I highly recommend Dr. Leong as your PCP. Advocate Aurora, overall, is an excellent health system I have enjoyed being a part of. The services are professional, prompt and handled very well. The facilities are clean and up to date. The staff is courteous, receptive and helpful with respect to scheduling, billing, and any other concerns. I have stayed with Advocate for nearly a decade and do not plan on changing soon, outside potential scheduling issues due to my recent move.

Dr Seng Leong and his staff are incredibly knowledgeable, compassionate and friendly! I recommend him every chance I get Bill Hoidas
