Amazing visit today w Dr Szeto! My son is 30yo and autistic. She listened, spent time with us, and offered two different options for some of our main concerns; including a fecal sample done by mail and a dietician for his problems with meals given in his group home. Way to be Dr ! Ty

She is best and explaining the procedure that you did on me I was nervous and when she explained to me what she was doing and that everything was going to be all right I was super calm. Dr Winnie is one of the best doctors that you have doctors like her. God bless her and her family. 🙏❤️🙂

Dr Winnie Szeto is top notch gastroenterologist and very caring person. She will treat you with respect and you will feel like she is your friend or a family member. Very humble person and very smart Dr. Please look no further, if something is going on with your stomach areas , you need her only. This is my experience with her. You will be so happy to have her for your treatment.
