Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Temperamental and grossly negligent
Demeanor from one office visit to the next was erratic, often flippant and dismissive, or hijacking the conversation with her own personal problems. Frequently failed to do basic administrative tasks like responding to request for information from insurance providers or social security. She failed to respond to repeated requests from my pharmacy for just a basic prescription renewal, requiring no PA or special handling,for a critical daily medication, without which death could result. When confronted she agreed I needed the medication as she had previously prescribed but stated in off put and demented fashion that she was too busy and will no longer be responding to any requests from cvs (my pharmacy at the time) regarding any of my medications. Like the usual and customary communications doctors have to have with pharmacies to make sure their patients get their prescriptions was something she could just opt out of and still be a real doctor providing any standard of care.

Do Not Trust Your Health to This Person
Dr. Sue Lalla-Reddy Is the most incompetent, horrible, unprofessional, emotionally removed, non-caring, individual. These shortcomings are reflected in her office staff, and total lack of patient care. She should absolutely not be licensed to practice medicine.

Never met her in two years. Rude on the telephone and highly arrogant, uninterested in patient care. Terrible experience. I do not advice seeking medical help from her or her office.

Amazing doctor and I would highly recommend her , I have been going to Dr Reddy's office for over 3 years now. Her staff are the kindest, her office manager is great at assisting me with any questions I have. Dr Reddy herself is always timely with me, and she always asks me if I would want an appt with her or other providers available for fastest service. I recommend her office and staff to all my friends and family.

Dr. Reddy is a caring and honest physician. She is always up front with me and asks about my emotional as well as physical health. She directly connected me with services to get help with my medication payments and housing assistance. She really cares about her patients and feels like a family there.

I'm a real patient that actually consistently goes to doctor Reddy and therefore my review is legit. She is awesome , period. Maybe there are some patients on here that saw her and she referred them out because she couldn't help them and they were upset at the world or something. But wouldn't you want a doctor that knows her strengths and knows when another professional might be better off? I feel reviews shouldn't be published because of a doctor's referral you were unhappy with? what does it have to do with the doctor at hand?
