in Mission Viejo |
Dr. Manasson has excellent follow-through. She always calls me with results of testing, even on the weekends. She spends time with her patients, making sure that everything is covered, from diagnosis to recommendation and referrals. I have never waited longer that 15 minutes and she doesn't schedule her patients so often that you are waiting forever to see her. I would strongly recommend her.

Dr. Manasson is very details oriented. She is great about referring to another physician speciality when she feels this is necessary. She explains her concerns & her resolutions.
in Mission Viejo, CA |
I always have a wonderful experience with Dr. Katherine Manasson and her office medical assistant. Dr. Katherine takes the time to thoroughly examine me, explain her observations, answer all my questions and come up with the best professional action plan. I have the highest praise to Xochtl (Dr. staff member). She is extremely helpful with insurance, referral letters and scheduling issues. I would highly recommend Dr. Katherine and her staff to anybody.

Dr. Manasson treats her patients at higher grade. She is very responsible, her referenced specialists are the best in the area.
Huntington Beach, CA |
Dr Manasson has been the primary physician of my mother for over 7 years and she has given the best care since. Not only is she very knowledgeable, she is very thorough and caring. I have not experienced a doctor who truly takes the time and attention each time my mother visits her. Very recommendable!
in Irvine, CA |
Dr Manasson is one of the most knowledgeable and caring doctors I have had over the years. She repeatedly went out of her way on my behalf to make sure that my insurance company covers the prescribed treatment.
in Aliso Viejo |
Doctor Manasson is just ok but her staff is extremely rude and disrespectful. The receptionist has really bad attitude all the time and does not follow on anything. I was referred to a specialist and she has never faxed papers that she supposed to send to him. She will not follow on anything even after multiple calls. I will never recommend to deal with this office . Two years in a raw I had morning appointments and was waiting for an hour, nobody came on time.
in Laguna Niguel, CA |
She listens well and spends plenty of time with patients and is very caring about her patients. Her judgment is very good and she follows with test results and provides detailed instructions on prescription drugs and diet. Overall I found her more caring than many doctors I had in the past who mostly focused on the business rather than wellness of their patients.
