Dr. Curtis Siu, MD

GPs get a variety of questions and Dr. Siu is ready to opine. He is also conveniently located near Laguna Woods. Kudos to his assistant Kim as well!

This dr is unavailable and his staff do not return calls even after the 24 to 48 hrs they tell you to wait. This dr lacks any bedside manner, is rude and at times obnoxious. Luckily I found another Dr who was able to accurately diagnose and treat problems this Dr was incapable of addressing or treating. This is your warning if you are reading this, beware.

Dr. Siu is efficient, thorough, compassionate and extremely knowledgeable….He takes the time to explain things that you completely understand it before you leave the office. Also, his medical assistant,Kim ,is amazing…. A great office and experience.

Caring staff and friendly excellent service

Dr. C. Siu is the greatest. He is very compassionate and patient listening to the patients and take extra time to explain the symptoms, diagnosis and treatment plans. He is very responsive in responding to our inquiries and good at follow ups. He has been our family doctors for almost 9 years. We would highly recommend family and friends to see him as their medical doctor.

He is the best doctor ever. He takes time to explain every aspect of one’s ailment. He talks to you on your level not over your head. He is extremely knowledgeable. His office is very timely in there response to any contact made whether it be appointment or medical concern. His assistant Kim is also very attentive and personable. I drive over 45 minutes to se him and it’s worth the time

It’s always good to see Dr Siu! He doesn’t rush thru the visit, but takes all the time necessary to explain something....and he listens when we talk!! My husband and I have been under his care for several years and thankful for him and his knowledge. His assistant Kim is absolutely wonderful!!!

Dr siu saw my special needs brother. He included my brother in the conversation which my brother appreciated. He was ontime. Gave good advice and encouraged my brother to be healthy

Dr. Siu is always congenial, straight to the point, clear in his explanations and never in a rush. His assistant Kim is amazing! I’ve never had as good an experience at a doctors office as the experiences I’ve had since seeing Dr. Siu for the past four years. Please don’t change.

Dr. Siu is kind, compassionate and most of all extremely knowledgeable.... recently, I thought what I had was a sinus infection and he diagnosed me as having a migraine. He helped me to understand the difference and gave me medicine that helped me very much. Most of all he was so considerate about how poorly I was feeling with sensitivity to light and sound at the office visit.... I was very grateful to feel listened to and to be helped....highly recommend Dr. Siu.

Like other visits, Doctor Siu is a focused listener, thoughtful questioner,and straightforward communicator. More often then not he makes a diagnosis and recommends a course of treatment but will readily refer if needed. I have been his patient for seven years. No complaints to offer.

Dr. Siu has been keeping me healthy for over six years. He listens carefully and asks the right questions. He takes the time to explain and answer any concerns. He is very thorough and makes excellent referrals to specialists when needed. He responds quickly to urgent matters and doesn’t keep you waiting!

Excellent primary care doctor. So thankful that we chose Dr Siu after moving here. He and his assistant Kim are wonderful.

Dr Siu is very caring and very thorough. He explores every detail of your condition and refers to a Specialist wherever necessary

Dr. Siu has been my Internist for nearly 15 years during which time I have been an all too frequent consumer of healthcare. From the start it was obvious that he is extremely intelligent, knowledgeable, attentive, analytical, and friendly. Over the years I have come to know him as compassionate, caring, always willing to listen, responsive, and a provider of outstanding care. The fact that his Assistant, Kim, is awesome and has been with him all these years, also speaks volumes. My educational and career background were in medicine, so I speak from a place of experience. I had appointments it’s five other Internists in South OC before asking Dr. Siu to accept me as his patient. I’ll always be grateful that he did.

So far extremely happy with how thorough and attentive Dr. Siu has been.

During the past 15 years, Dr. Curtis W. Siu & his medical assistant (Kim) have provided the highest standard in medical practice & patient care. I hold the highest regard for Dr. Siu’s professionalism. Thank you.
