A good and compassionate listener who offers good advice of how I can assist with the healing of my medical condition.
Wahiawa, HI |
Dr. Jao and his staff were just great. Handled several problems that I had, helped with rehab, new procedures. Easy to schedule a series of appointments. I am moving to the SF Bay Area, and Dr. Jao recommended several doctors, very helpful. Always had time for me, interested in how I was doing generally. Was available to me on a weekend when I had ultimately had emergency surgery (from another doctor),

Took my teenager to see him due good referral but after 3 visits didn't meet him once. Very disappointing meeting only with his "associate" who said "under his instructions" therefore went to look for another Dr who was willing to see us & make us feel wanted, valued & important enough to at least meet us once even if we need to drive to town.

Dr. Jao has the best bedside manner and caring treatment I have experienced. He truly cares about his patient's overall health and how lifestyle, wellness, and outlook on life can affect your health. Not only is he judicious in prescribing medications, he looks for ways to improve gastro problems with diet and overall fitness. Thank you Dr. Jao!

Dr. Jao, has treated me with utmost professionalism, skill and compassion. He has exhibited a high level of knowledge and competence in treating my condition. I am here today, and able to enjoy my life due to my being in the care of Dr. Robert Jao, Shiho Nakano APRN-Rx, FNP-BC, and his entire staff.
in Honolulu, HI |
Dr. Jao takes the time not only to explain what your medication problems/issues are but also to listen to your questions or concerns. After seeing several specialists, he didn't take the other doctors words as fact, but instead started at the beginning. Also, I never felt treated like I was in an assembly line. He devotes and dedicated enough time to assist me in a complete manner.
in Kaneohe, HI |
Doctor Jao is the absolutely the best for my personal Heath care! I do and will recommend him to all my friends and family!
in Honolulu, HI |
I have been seeing Dr. Jao for over a year now and I cannot commend him enough for his excellent skills in communicating with me, treating my health issues, and making me understand the importance of many aspects to health and treatment. He is a very kind, generous, thoughtful, understanding, and comfortable gastorentologist, and I would recommend him to anyone who is need of services relevant to his practice. Without a doubt Dr. Jao is one of the best doctors I have ever encountered in my life.

Dr. Jao is a soft-spoken, experienced, knowledgeable and very caring physician. He is patient, thorough, listens well and provides honest diagnoses and explanations.
in Honolulu, HI |
Dr. Jao was super busy, so they gave me his Physicians Asst..She missed diagnosed me..After the weekend of putting wrong medication on, I got to see Dr. Jao.. He was fine. The front office Sarah is fabulous ..But, NOT his Office manager and nurse, Noreko . She doesn't return calls that she promises..or seems to care at all.. For this reason, I would not go again to this practice..
in Waipahu, HI |
He's terrific. Very gentle, very kind, forthcoming with information about the diagnosis he makes, and competent at procedures. He is a doctor you can trust.
