The Providers

Yohan Park, MD

Attending Physician

Hello everyone!  My name is Dr. Yohan Park and I would like to introduce myself. I am a pediatrician in Bayside, Queens. Coming from a family of physicians, I learned early on, the importance of providing care and compassion to family members who have entrusted their loved ones in my hands.

Lisa Guan

Pediatric Nurse Practitioner

Hello everyone, my name is Lisa Guan. I am a Board Certified Pediatric Nurse Practitioner. I have been working as a Pediatric NP for more than 10 years. My clinical interest include management of pediatric primary care, developmental screening, asthma, allergic disorders, dermatological conditions, obesity/nutrition, and adolescent medicine.

Esther Sung, MD

Pediatrician

Hello, I am the newest provider at Bayside Pediatrics, PC.  I grew up in Queens most of my childhood and adolescent years and spent most of my medical career in the tristate area only to return to Queens where my earliest memories began.  I am enthusiastic about Pediatrics and Adolescent Medicine and observe how the changes over the years have impacted the health of our children and families.  My particular interest is in complementary medicine and nutrition and the growing influence it will have on the traditional practice of Pediatrics.  To help support the mental and spiritual health of the middle and high school students, I volunteer and serve the youth group at my church in Queens. When I am not working, I enjoy spending time with my family and son hiking, traveling, and dining together.   My personal hobbies include baking and reading.  I look forward to working with you to provide care that addresses all aspects of your child’s health.
