Get to Know Me

In addition to being a pediatrician, I am also a father. Being a father has been one of the best blessings in my life. I currently have a toddler and my wife is expecting another baby! I love to share my parenting tips as a pediatrician with other parents, especially parents who have children close in age to mine!  

Why I Treat Children

Children have an energy about them that is contagious. They bring joy and light to my day every day. I can’t help but smile when I hear a child giggling in the exam room or when they grab my stethoscope because they want to examine it.   

What I'm Passionate About

I am passionate about the child and the family unit. I love to see parents being involved and supporting their children. I believe that this starts when the child is a newborn. I am passionate about guiding parents during the newborn period, which can be delightful, but also challenging.  

How I Try to Make A Difference

I promise that I will be present during the encounter and listen to your child’s needs. I pride myself in being gentle and kind. I will always advocate for your child.
