What our patients are saying about us:
OUR PATIENT EXPERIENCE (COMMENTS FROM YELP, SHARECARE AND HEALTHGRADES)
- Dr Katneni and her staff are on top of it and listened to my condition.
I feel I was heard and Dr Katneni is taking additional precautions to monitor for my future health as well.
Very easy to talk to , caring and knowledgable.
She also had all my records available to ask about other medications I had and know my full work up.
Patty at the front desk helped facilitate appointments and getting me dialed in.
I am very happy I chose their practice.
Sincerely
Kurt

1/26/2024My husband is being treated by doctor Katneni. I am always present during the time he is being cared for as he has problems communicating. I am an RN by profession and can tell you that Dr Katneni is very efficient, has excellent ways of communicating and cares truly for her patients. Patty at the front desk is one of the most professional medical assistant I have seen and ensures that all is going well during the visits and follow up. I HIGHLY recommend this doctor and her staff.

- 10/30/2023Dr. Katneni has went above and beyond to help my mother Virginia Purmort as a kidney specialist. I highly recommend her. She cares for my mom like it was her own. My mom adores her. She always finds a solution for her kidney care. She takes her own personal time to call my mother at home at anytime. We continue to see my mom health improving with her help.

- 10/25/2023Dr KATNENI is one of the most caring and supportive doctor I've met in a very long time.
I met her as the Nephrologist on staff at Hoag Irvine.
I continued to see her for 4 months after being discharged. She kept a very close eye on me about every two weeks, with ordering different labs. My blood pressure was not consistent until today. She was very happy with my numbers. I have continued to feel so much better than ever before!
She spent a lot of time with me on each visit. Returning my calls promptly and taking care of my need's immediately via my pharmacy.
He office manager is very friendly and always took my calls. Quality of service from all affected with her practice is friendly and professional. I was very scared when entered the hospital but I met Dr KATNENI and she will be my nephrologist forever!!
Thank you Dr Katneni for getting me back to a healthy and happy life

- 1/19/2023Dr. Katneni is kind, compassionate and genuinely cares about her patients. You can expect her full attention and a thorough examination. She is an internist that specializes in nephrology (kidneys) and hypertension (high blood pressure). Her office is small and cozy and there is always ample parking available. The office staff is friendly and attentive. Whether you are looking for a primary care physician, a kidney specialist, or even just a second opinion, you can't go wrong here. Dr. Katneni is accepting new patients. Do yourself a favor and start here.Report review

Dr Katneni has made me feel so incredibly comfortable and well taken care of. I was in awe of how she and her office helped me navigate getting bloodwork and new insurance. They guided me every step of the way and i am certain i am in the best of hands with Dr K as my doctor!

She's really good and accessible quite easily. I was able to make a next day appointment with her just before she was to close. She's also great at human relationships and extremely friendly. Highly recommend
