My family and I have been going here for several years, and the staff is always wonderful, service time is prompt and very professional doctors and great hours of operation. They have gone out of their way to get my son's physical worked in for a deadline.
I can't say enough good things about this place. I went in for a physical last month and had a great experience (well as great as a physical can get). Called in and the receptionist was pleasant and found a date and time to fit my schedule. The waiting room was clean and neat. Everyone was nice and friendly. The doc listened to me and made me feel comfortable. They have a lab on site to draw my blood. I got the results on-line and I was sent an email when they were ready! Too cool!
Usually minimal wait times. Knowledgeable Doctors who really care. Friendly. They have their own Phlebotomist so you don't need to go elsewhere to have blood drawn. Have weekday after-hours and Saturday appointments!
They are professional, like family, and very caring.
I really liked coming here and feel I was really taken good care of by my doctor. I definitely will continue to come back here as my primary care facility.
Excellent – no waiting time. Everyone was very professional and courteous.
I have had great care and attention from the busy staff and Doctors. I have never seen rude treatment by the staff. They draw basic labs with an outside provider right in the office.
My family and I have been going to this practice for years now and we love them. I would recommend it to all my friends/family.
Dr. Hwang is great. The office has always been helpful. Appointments are easy to make, hours are convenient and the modern online medical records/correspondence site is excellent. I love being able to see my appointments and tests history.
This is an all-star practice. Dr. Hwang came highly recommended to us by our doula and he has been caring for our baby boy since birth. No concern is too small and Dr. Hwang makes my whole family feel very comfortable. The nurses are kind and the office staff is very helpful. Stop looking for a pediatrician and go see Dr. Hwang!
