Practice philosophy

Natural first. Surgery only when it's the best option.

Trained in Western surgical medicine with a proctology subspecialty, Dr. Rosenfeld practices with a holistic ideology: all patients are different, so one-size-fits-all is not the way to practice medicine.

When appropriate, therapy begins with all-natural products — unadulterated psyllium fiber, plant-based bioflavonoid antioxidants, probiotics, L-Glutamine.
