Hiep D Dang, DO

My husband and I have been patients for years, we love Dr. Dang and his staff. My husband's a storyteller and the doctor is always so patient. My husband went thru a bad health crisis a few years ago and we were in their office and calling them quite a bit and the they were always so helpful, we never felt any frustration from their team. I work in the medical field and appreciate the fact that the doctor requests regular check ups for med refills, it's important to touch bases with your patients. I would recommend Dr. Dang to anyone searching for a caring physician.

I want to express my sincere appreciation for Dr. Hiep Dang and his entire office staff. Dr. Dang's thoughtful, attentive care makes every visit feel reassuring and personal. His team is equally kind, professional, and supportive, creating an environment where patients truly feel cared for. Thank you for the exceptional service you provide.

The doctor is awesome and very listen, care and take time to check on patient. I love how he take time to discuss any concern that I worry about my health and he always recommend that patient should do the test to make sure everything is okay

Staff and doctor are professional and kind. Would recommend.

Dr Dang and his staff are terrific. Kind, thorough, and professional. I highly recommend

Although the office is small but the most importantly is all the receptionist here are so sweet and helpful. They keep you posted with any concerns or questions you may have. What we I like about Dr. Hiep is he is caring and concerns for our well being. He don't mind telling my husband to exercise and lose more weight.

Lucy at Dr. Dang's office is the best. She is knowledgeable, helpful, patient, caring, and is someone I can depend on when I need information. Thank you Lucy for all you do!

His attentiveness and thoroughness in every appointment ensure that no concern is overlooked, fostering a trusting and reassuring patient-doctor relationship. Dr. Dang's approach is both professional and personal; he takes the time to listen and understand my health concerns, providing clear explanations and tailored advice that demonstrate his commitment to my well-being.

Dr Dang is a very good physician. Working in the medical field myself, I am usually very skeptical but I have to say Dr Dang has my complete trust in taking care of my mom. He always addresses our concern and questions promptly and kindly. Yes some people may be bothered by how often (a couple times a year) he requires his patients to come back for a check up, but this is the sign of a good physician who actually cares about you. The office staff are also courteous and treat my mom well. This is rare among the many Vietnamese physician office in the area. Highly recommend!

Doctor Hiep Dang is the best doctor .. very polite and professional... I hah gone with him since 2012

The office staffs(Lucy& Thī) are unprofessional, and incompetent. Due to changes in insurance medical group.I had selected Dr Hiep as my family primary care Dr & based on iprovider listings he's accepting new patients. My daughter injured her left knee during soccer tournament, & is recovering from ACL on her right knee & is still under care with a specialist . I called the office & requesting for my daughter to be seen for her left knee..I was told they don't have an appointment available& the next available appointment will be in 3 months. I was able to convinced the staff to scheduled appointment(much appreciated). I gave the staff my insurance information & she said she'll call me back & she did only to tell me I'm not in network & that Dr Hiep is not my primary care physician. I told her I have the insurance card and Dr Hiep is my physician. Staff told me I have to call my insurance and figure that out. I called my insurance & the agent was nice enough to call the office & straight things out. My daughter was seen. Now back to her ACL on her right knee, because we switch medical group we need another referral to see the same surgeon . So another appointment is needed & they again ask my daughter to do a walk in (wait time is expected). Dr requested authorization & call me back saying authorization for my daughter to be seen is denied because it's not a medical reason.. she had an ACL surgery & needed follow up how is that not a medical reason . I was then told by Lucy to call my insurance (what's her job then?). I called the insurance company & the agent told me the code drs office used is vague and doesn't specify the conditions & it's for left knee.. I called the specialist office to obtain the codes that Dr can use to request the authorization. Lucy said ok she'll submit another request. Called me bout week later saying request denied because my daughter's almost 18 & the specialist is a pediatrician specialist ..Hmmmh almost 18 but she's not. Again I was told to called the insurance. I explained the situation to the insurance agent & they said the reason was because they want to use the medical group Dr before using other medical group Dr. I called the office Lucy puts me on hold for 10 mins & return with the same reason of denial almost 18 years of age. I've had enough with the staffs & requested for a call back from Dr Hiep maybe I can explained & we can get the approval. I received a call back from a lady claiming she's the office manager I told the her the situation then she's saids she the Dr sister!!? I'm not getting anything out of this office lies after lies. She didn't even put in the effort of offer: let me talk to the Dr see what we could do to get the approval for my daughter to be seen by her surgeon instead sending her to a Dr with no history of my daughter condition( no offense). even after I told her I want my daughter to continued to be under the surgeon care. All i was told is how great the staffs are. I wouldn't want anyone to lose their job but staffs need to be re-train. I'm done with the office.

A lady picked up my call and told me to hold and I have been waiting for six minutes. I called again and she told me the same and let me wait! I don't know how they operated but this is not professional

Hiep dang is the worst doctor. Do not visit. If you want your relative to survive then going with another good doctor. Hiep dang is trying to send patients to the fountain valley regional hospital and killing them and share monies among his friend , all of monies come from Medicare.
