About Me

Dr. Sebastian Sylvestre holds a Bachelor of Arts degree in biology from Boston University. He also earned his medical degree from Boston University School of Medicine before completing both his residency in Pediatrics and his fellowship in Allergy and Immunology at Penn State Health Milton S. Hershey Medical Center.

Dr. Sylvestre’s philosophy of care is to collaborate with each patient by listening to their concerns and implementing evidence-based care in an individualized manner. His background in both Pediatrics and Allergy and Immunology enables him to uniquely tailor care to both children and adults alike.

Volunteerism and advocacy are two hallmarks of Dr. Sylvestre’s career. As an undergraduate student in Boston, he volunteered at the Boston Marathon. During medical school, he advocated for increased academic and support services for individuals with disabilities. Then during his Pediatrics residency, he was able to do a rotation abroad in Ghana in a resource-limited hospital.

“I have always tried to make myself available in service to others,” said Dr. Sylvestre.

Being outdoors is a special interest to Dr. Sylvestre, who stays fit by playing soccer, tennis, jogging, hiking, and skiing.

“I always try to keep moving,” said Dr. Sylvestre. “I’m fortunate that State College is so close to some really great outdoor activities and the convenience of a local airport that can connect to other major airports is also a great thing.”

    Dr. Sylvestre is an excellent doctor. My one suggestion is that he talk a little slower. I'm not dumb or deaf, but need a little more time to process what he is saying.

    Only criticism is that it was very clear that he was on the clockwhileHe answered all of my questions but I felt like I was rushing him. I felt like he knew the answer before the question was presented.

    Dr. Sylvestre talked about my breathing issues with me and recommended new medicines to control my asthma. He gave me reasons why I should take these and discussed any side effects. My other allergist (that I'm leaving) hasn't done that for me. Dr. Sylvestre was also very active on the patient portal messaging system. I didn't have to wait long for a response. He is very energetic, almost too much ha ha.

    I was just there for an allergy injection- the nurses are fantastic. I typically see Dr. Ishmael for appointments- he's great too!

“As Allergy and Immunology can often be a specialty of fine nuances, utilization of a shared decision-making process will typically guide treatment options to an answer that is best for patients and that they are most comfortable with."
