Dr. Tomaszewski is awesome. He actually takes time to talk to his patients & never makes anyone feel like he is rushing.

My wife and I agree this is the best primary care physician we've ever had. He takes the time to truly listen, never rushes appointments, and explains things clearly and thoughtfully. We always feel heard, respected, and confident in the care plan when we leave. He combines clinical excellence with genuine compassion, which is rare. We trust him completely and feel very fortunate to have him as our physician.
