John Ghassan, DO


Practices In: Downers Grove, Naperville, Plainfield
Patients Seen: Children and Adolescents

My name is Dr. John or Dr. Ghas­san, whichev­er you and your child pre­fer. I went into pedi­atrics to help elim­i­nate any med­ical, emo­tion­al, behav­ioral or social bar­ri­ers that your child may encounter as they grow and devel­op into young adults. I want every child to have the oppor­tu­ni­ty to suc­ceed at what­ev­er they desire with­out wor­ry­ing about their health. I grew up play­ing bas­ket­ball and vol­ley­ball, so of course my per­son­al prac­tice style is team-based. The team con­sists of the child, the par­ents, me (the pedi­a­tri­cian) and any­one else we may need to include to ensure the health and suc­cess of your child. You should also know that I prac­tice evi­dence-based med­i­cine, and I am con­tin­u­ous­ly read­ing and lis­ten­ing to pod­casts to stay up-to-date on the lat­est changes in med­i­cine. I love teach­ing and keep­ing my fam­i­lies and patients informed. Last­ly, I believe the best pedi­a­tri­cians are intel­li­gent, avail­able, car­ing, fun, hard­work­ing, resource­ful and will always have their patients’ best inter­ests in mind. There­fore, I try to be all that and more for my patients and their families.

Personal Interests

My wife, Han­nah, and I grew up in Naperville, and we are excit­ed to be back home. In 2020, we wel­comed our daugh­ter, Izzie, to the fam­i­ly. The three of us love going on walks out­side, going to parks and eat­ing good food. I also still play bas­ket­ball and sand vol­ley­ball when­ev­er I get the chance.
