Philosophy of care | As a neurosurgeon, I believe in delivering precise, evidence-based care grounded in thoughtful decision-making and deep respect for each patient’s unique experience. My goal is to guide you through complex diagnoses with clarity, compassion and honesty – always prioritizing what is safest, most effective and most aligned with your values. Sometimes that may even mean no surgery at all. Ultimately, I see neurosurgery not just as a technical discipline, but as a human one – where careful listening, deliberate action and lifelong learning are essential to achieving the best outcomes. | Why I entered medicine | I was drawn to biology by a fascination with how the body works – particularly the complexity of the brain. But what ultimately drew me to medicine was the opportunity to apply that science in a way that directly improves people’s lives. I find deep purpose in using the rigor of neuroscience and the precision of surgery to help patients through some of their most challenging moments. Medicine allows me to engage both intellectually and personally – bringing together knowledge, skill and compassion to make a real difference each day. | Community involvement | I’m proud to be joining the Lehigh Valley community and committed to providing the highest level of neurosurgical care right here at home. I will be working to become embedded in the fabric of the medical community of this region such that primary care and specialists are all working together to better educate and take care of those who live here. | Personal interests | I enjoy staying active (running, swimming, biking) and spending time with my family. My wife is a physician as well and we have two young children. Together, my family brings me joy and keeps me grounded daily.
