About Me

Born in New York, Sue Lalla-Reddy, MD has been active in the medical field for more than 10 years.

Dr. Reddy completed her Internal Medicine Residency and Infectious Disease Fellowship in 1992 at St. Luke’s-Roosevelt Hospital in New York. She has worked in both a staff position and as a consultant at several hospitals in New York, New Jersey and California.

Dr. Reddy has certifications and experience in various cosmetic procedures, including facial fillers and Botox therapy, and specializes in HPV management for homosexual men.  Along with an abundance of teaching experience, including providing an opportunity for medical students to rotate through her office, she has given many lectures and has participated in many breakthrough clinical trials.

She is currently the administrator of the Santa Ana Jail Medical Clinic, and provides transgender and specialty medical care for the inmates. Dr. Reddy has also worked for Ryan White Programs specializing in care for HIV positive women, and has helped manage infection control in hospital settings.

She is actively launching an IV infusion center for outpatient IV antibiotics and other outpatient infusion options to help patients continue their care in their homes instead of in the hospital or in nursing home facilities.

Dr. Reddy also makes time to give back to the community and volunteers as an active board member with the AIDS Services Foundation and travels with her family to provide free medical and HIV care in various countries. She often speaks yearly at the International AIDS conference held in India, and donates her time and services for various causes.
