Dr. Jeffrey Zweig


“I treat each patient as I would a family member, seeing them as a unique individual, with their own set of goals, wishes, and expectations. Prior to recommending a specific treatment regimen, it is important for me to get to know them, including their background, family and interests, so that together we can form a personalized medical plan implementing the most up-to-date therapies. I believe it is also vital for patients to get to know me, as creating a comfortable patient-physician relationship allows for a strong level of trust and effective bi-directional communication.”
