The doctor was very kind and listened to all my questions. I think he was very understanding of my situation and made me feel good, like he was listening and paying attention. I think he did an excellent job with me, and I would definitely recommend him to anyone looking for this service. Thank you so much.

Dr. Karki makes me feel like I'm his only patient, like his best patient. He sits down, he's interested in what I have to say, and he always helps me problem solve. I've never experienced a doctor like this in all of my years of receiving healthcare.

This is all good, but don't waste my time with a phone call and an email.

Dr. Karki was able to not just show me why I should continue taking certain medication, but was able to recommend me to the appropriate specialist to find the actual cause of certain headaches that I was receiving. And I'm just so grateful that he took the time to listen and to understand my needs to get me to the appropriate place to get the results that I have today. Thank you.

Dr. Karki and his staff were great! I loved the personal attentiveness I received from both doctor and his staff. I was so relieved to have my problems explained to me in a manner I could completely relate to and understand...I had nothing but a fantastic experience!

Dr. Karki explains things to you almost like an alien intern so you can understand everything he's saying. He's a very good communicator and I would recommend him to anybody.

absolute confidence in Dr. Karki and trust his abilities and could not ask for a better

The only problem I had was when I was put in the room, the doctor didn't know I was in there. I had to go open the door, and they didn't even know. The doctor said, oh, nobody told me that you were in there. So it was mainly his assistant that was the issue for me. She put me in the room, and he didn't know about it. And he apologized, and he was a great doctor. I feel like I don't want to go back because of the treatment that has been provided. Thank you.

Dr. Karki listened to my concerns, frustrations and Dr. Karki spoke of different options available to my care. I was at ease, comfortable and my questions were answered. I made a next day Appt. For a voiding Ultrasound and I am so Happy with PIH Hospitals, and Radiology and surgical Departments. Thank you for the much needed information Dr. Karki; I feel like there is hope for my situation. I am very Pleased so far.

Dr. Karki was amazing. He took the time to carefully review my medical history with all the previous PIH doctors and showed a clear understanding of my condition. He asked several thoughtful questions and had a strong sense of direction for next steps in my care. One thing I'd like to mention is that during our conversation, I told him how lifting my legs helps alleviate the pain I've been experiencing. I didn't see that reflected in the visit notes, and while I really appreciated his thorough recap overall, I wish there had been a section that included the methods I personally use to manage the pain - like using a cane for two years, only being able to walk about 200 feet before needing to sit down, and elevating my legs. These are important details for me, especially as I'm in the process of applying for Social Security benefits. Overall, I'm very grateful for the quality of care I received.

Dr. took his time with me to explain everything that was going on with me in a simple and easy manner for me to comprehend since my mind is not working very well. I really appreciated that!
