Always listens to me and what is going on, changes medication when needed. Have no trouble getting an appointment with him, even though he is very busy. I wouldn’t change doctors for anything. Takes good care of my husband also. His being so busy should tell you that others feel the same and want him to be their doctor

He is the best doctor I ever had! (22 years). He took great care of my Mother when she was alive! (11 years). And now is taking care of my Father and my daughter. He and his staff are very kind and understanding. On time appointments. Accurate diagnosis. Allways available. Easy to get ahold of.

Dr. Karanjai has been my doctor for over 20 years. Even though he is very busy, he is patient with me and my father too. He covers all our health issues and is always very happy to be with! All of his staff are well educated and very friendly! Appointments are prompt and they somehow allways have time to squeeze me in. As a doctor he has all the necessary tests done to make sure that I am healthy. I appreciate him and I am very glad that he is my doctor. Thank you and your staff for taking good care of me!!

My appts kept getting changed, each time it was an extra month to wait. I've had enough and went in to have records transferred elsewhere

Dr is very kind and makes sure to take time on all of his patients. He makes sure I fit into his schedule even when he is so busy. His staff could improve but overall, I have been seeing him for a few years now and it is great.

I like Dr. Karanjai as a doctor, and he has seen me at the worst of my health. But getting to him is always tough. The lady at the front desk, Rhonda...... who has been there for years....... has got to be by far the most insensitive, rude, and nonunderstanding person to ever work in a doctors office. She always seems overwhelmed with everything. Good luck getting through the wall of Rhonda to see Dr. Karanjai.
