​​Words from Dr. Nath

"In a new era of medicine where the landscape of healthcare has increasingly shifted towards a mere numbers game premised upon patient volume,

quality of individualized patient care remains my paramount priority with patients treated as family members most deserving of my undivided attention and time."
