Dr. Tjahjana takes good care of her patients.
I was very pleased with the new nurse practitioner I had when I came in on 8/22. I saw her becase the doctor and Amy was busy with other patients. It was a breath of fresh air, she had a great bedside manner and I found her engaging, funny and made me feel comfortable. I hope she will be a regular at your practice.

Always a pleasure to visit Amy and have her help with my medical matters.
Dr. Tjahjana is great! She cares about her patients. She’s very compassionate and understanding, and most thorough physicians I have seen. They do an EKG for every annual checkup. Dr. Tjahjana always takes her time to explain things to me. The lady who does bloodwork was super gentle and experienced, when she noticed my daughter was afraid of needles she not only comforted her but also changed to a small needle to accommodate her. Everyone on the team is super nice!
Always caring and attentive to patient’s issues
Amy truly cares about her patients, she takes time to help them with their health issues. She is very understanding and professional.
I had a very good experience with Amy. She responded to my call promptly and in the absence of the Doctor, she was able to provide details of my test results satisfactorily.
Dr. Ming is an amazing provider, she is very knowledgeable and very good at what she does. Thank you so much for all that you do! I appreciate you so much! ⭐️⭐️⭐️⭐️⭐️
I heard that Amy Peng is leaving the practice. I am sorry to hear this, as she has been an integral part of my and my husband's health care over the years. She is a good listener, which can be rare these days. She is also a caring, knowledgeable NP whose advice is straightforward and relevant. We are truly sorry to see her leave the practice and wish her and her family the best

She gives me all the time I need to understand my ailments and how to treat them. I appreciate the time she gives me when listening to what I have to say. She doesn't just listen "She hears what I try to tell her. Also, I love her staff. I look forward to seeing their friendly faces, and the welcoming greeting I get when I enter the office. If you are looking for a doctor who is going to meat all of your medical needs, this is the person immediately come to mind would .
Dr. Tjahjana is one of the best doctors in Internal Medicine, Diabetes, Arthritis and other problems. I moved to Florida and still cannot find a doctor like her. She cares about her patients which is what we look for. Patients in Virginia are like to have her as her Primary Doctor.
