    She listens to me. You know how important this is if you have ever had a doctor who did not listen. She takes time necessary and does not hurry to shoo me out. She answers texts via the patient portal and phones me when appropriate.

    Professional, compassionate, knowledgeable, communicates effectively, thoroughly reviews health records, (including meds, labs, referrals), and listens with a warm heart. Dr Tan is a doctor that can put us at ease whether we have a difficult condition or proud of us for being on the right tract to our well being.

    She is not my primary care physician who is Dr Tawil. My problem was cellulitis on my left leg - I know that because I had the same thing occur on my right leg over a year ago and I waited too long to see a doctor the first time, so I saw the first appt I could get which was with Dr Tan. I had to wait a long time in the waiting room but it was worth it, she was wonderful, ordered a Rx for an antibiotic and a salve for me and a return date 10 days later.

    She goes through my lab results thoroughly with me every time. She is very knowledgeable and patient. She asks me if I have any questions. It is highly likely for me to recommend her bc she is the perfect doctor for adult medicine.
