August 2026

I'm writing this on behalf of my mom who is a patient of Dr. Rajni Sinha. The level of kindness, compassion and professionalism of this doctor is unmatched. From day one, we felt a level of comfort from her that calmed both of our spirits. My mom got diagnosed with breast cancer at the age of 83. As a 21-year breast cancer survivor myself, you can imagine my dismay and disbelief that my mom who walked me through all of these years was now experiencing breast cancer. She will turn 88 this year. She survived surgery and was referred to Dr. Sinha for continued care. That was the best decision ever! I could go on and on, but will just say that if anyone can walk you through this journey it would be Dr. Sinha. We have no problem recommending her to anyone.
