Dr. Troung, has been my Dr. for a few years now. I could not be happier. Every time I come in for my scheduled appointment I never wait more than 5 minutes even if I am early. The front staff is friendly and efficient. He truly is a friendly, caring, and patient Dr. He travels the world spreading his knowledge and new visions to his colleagues and still maintains a high volume practice. Do to my present financial situation he performs additional needed treatments out of his own pocket to assure I have all the appropriate procedures done. I am fortunate to have a caring Dr. with the respect for the patient. Not about the money but being able to live a better life style. I highly recommend Dr. Troung. Truly one of a kind. Thank you for your continued support and concerns about my health and wellness. Sincerely Dan Smith read more

Dr Truong's Botox treatment was the first step to my father's death. After only being his patient for a couple months he administered Botox to his neck, causing him to be unable to swallow. YOU CANT REVERSE BOTOX. His options were to get a feeding tube, this led to an infection that went septic. His response to my family's tragedy was defensive and casual. My father's only ailment was Parkinson's and poor memory, he did not have life threatening conditions prior to this treatment, and he had the nerve to compare us watching our father starve to death to his wife who had passed from cancer?? I'm sorry for anyone's loss but it was unprofessional and disrespectful. He proceeded to text my mother treatment options after we told him our father's end of life wishes and not to contact us. DO NOT GO HERE read more

I was referred to Dr.Troung and told that he was the expert in Botox treatment for pain management. Upon meeting the doctor, I found him to be arrogant and dismissive which I could accept. However, he delayed the Botox treatment to my second visit and that was a disaster. He administered 500 units of Botox into my neck, which I learned after the appointment was the maximum dosage and should never had been the initial amount of Botox treatment. Within one day, the pain in my neck intensified and then I developed severe head drop. I contacted Dr. Troung's office 4 consecutive days and received promises to return my calls. It has been 8 weeks now. My symptoms have not improved and I have NEVER received a return call! My suggestion is that no one should trust or use this doctor and he should retire. read more

The receptionist who works on 3/27/2025 hung up on the phone, I have to call back for a appointment then received a response " call us back in 2 months" then hung up again. This person is Under-educated and non professional. read more

Old grumpy man. He should be more friendly. I think he should retired. Please read the reviews. But he did give medicine to relieve the tremors. read more

My mother was recently referred to Dr. Truong by her general doctor. She has recently been diagnosed with Parkinson disease and I am grateful for her being referred to Dr. Truong. I accompanied my mother her very first consultation. Dr. Truong took the time to explain the condition, possible treatment options, and the importance of managing her symptoms effectively. He ordered tests and scans so that we can get a handle of her condition and eventually formulate a treatment plan. Dr. Truong listened attentively to our concerns and ensured that my mother and I were as comfortable and empowered as possible. We feel so fortunate to have found such a skilled and compassionate doctor guiding us through this journey. read more

I am so grateful for Dr. Daniel Truong! He has compassionately cared for and supported me over the last thirty years due to spasmodic dysphonia. His medical skill has allowed my vocal disability to be a non issue in my career especially in a remote environment. Public speaking is a big part of how I am able to give back to my community and I would never be able to do so without his care. I am forever grateful to Dr. Truong! read more

Update after leaving Dr. Troung. Things back at UCI Gotshaulk Center have been great. My mother is back on her same dose of Parkinsons meds she was on before we meet Dr. Troung and she is doing fine. He had tried to quadruple her medication. We even had an emergency in is office where she almost fainted when he tried to increase her medication in the office with an inhaler (to see if more helped). After first saying she didn't look like she had Parkinsons, then running multiple expensive tests, then increasing her meds drastically only to say yes she had Parkinsons which we already knew for 10 years from her previous doctor who retired. The whole experience with Dr. Troung still haunts me and it's been over a year. Now my mother sees a separate neurologist for Dementia. Yes, she has dementia now. Apparently Parkinsons neurologists only treat movement disorders they don't treat dementia, you have to see a different neurologist. Which explains why when I told him my mother was having confusion he didn't address or treat her. Now my mother takes a new medication and it has helped keep her more interactive and alert and not in a daze like she was before. The new neurologist at UCI has a great moto that we already went by "if it ain't broke don't fix it" so it's nice to have a doctor on the same page instead of one who pushes medication that causes other problems and then tries to tell you side effects from too much medication are normal. One day she will need to increase her meds, and there will be side effects, however if we had started a year ago on 4x the dose she's on now, her quality of life would have gone down hill fast. She still gets out of bed, showers, gets dressed, and comes downstairs on her own all without more medication. read more

Dr. Truong gave my Mother back her life. She was in pain for years and other doctors could not help her. She was unable take care of herself or participate in any social activities. Dr. Truong recommended surgery and Botox treatments for her Dystonia. Now she is an active senior who volunteers to help others. She enjoys socializing with friends and family, even traveling back east to visit her grandson. Dr. Truong gives her treatments every 3 months so she can remain pain free. He is the most caring Doctor I have ever met. He goes above and beyond to help. Our entire family is forever grateful to him. read more

I don't really leave reviews but this one I must first visit at this office I saw a Dr name Christina very helpful actually had positive attitude an diagnosed me or stated what she thinks is wrong then transfer me to Dr truong Due to it being a complicated diagnosis or treatment or for second opinion being he is the head doctor of the office. . my first visit with him was horrible i am a compassionate person I try to give much detail information of how my problems occurred Dr truong really didn't care to hear any of it really he yelled at me while I was trying explain in further detail and my sister was trying to explain as well . When ask if he could check the pulsesation in my face he was really rough I also showed him physical movements I'm having and videos . He said he thinks I was causing the movements on my own . I've been suffering 2 years trying to get into a doctor office who specializes in movements . Many doctors have offered me Botox to help with the pain I was waiting to have a specialist in this type of problem do Botox due to nerves or muscle being injected correctly he offered nothing said he can't help didn't offer any testing my sister literally had to beg for some type of testing due to my other testing being outdated from previous doctor while waiting for movement specialist and new symptoms arising since then . I really regret wasting time I could of went eles where for help . No doctor should treat there patients this way . I really hope he gets mental health help because he is suffering loss of family and his age may be short fused to his patience levels . But to enhance that type negative energy on a patient's looking for help is beyond. After I think he felt a lil bad for his attitude but it's not ok . I hope he finds total healing as well . But I can't be treated in that type of environment. No one should . Maybe he should retire . I mean tear's actually came out my eyes from the frustration . On top of the pain I've already been dealing with just to be verbally abused . I came in with high spirit thinking I would finally get help are answer for my movements . There are just better ways to handle situations with your patients. Hope this helps someone . I wish I would of checked reviews before ever going. It's a shame we have to be belittle by doctors as if we are uneducated are undeserving to be treated as a decent human being due to are physical disabilities. Are because of doctors unfamiliar with the medical issue at hand . read more

This doctor is very rude and obnoxious to his fellow staff at the medical center. You should believe all the negative reviews from his patients because he treats his co-workers the same way. He treats workers at the hospital with disrespect and is condescending. He only respects other doctors. Everyone else he treats like garbage. I think his old age has made him very grumpy. He should just retire if he hates his job. He seems to always be in a bad mood. The employees all talk about what a bad attitude he has. read more

Dr. Daniel Truong is absolutely the best Neurologist! Having Dystonia, Dr. Truong has treated me for over 20 years. I would not go to anyone else. He has a great sense of humor and is a very compassionate person. read more

Dr. Troung is the finest neurologist I have ever met. I have dealt with Cervical Dystonia for many years. It took me several years to find a doctor as kind and knowledgeable as he. I have never felt better. His office staff is so nice and professional. A TRUE BLESSING! I recently had an appointment with Dr. Troung to help me find a treatment for my Restless Leg Syndrome. He sat and talked with me and examined me and gave me a wonderful medication which has really helped my RLS. He's such a great neurologist and so kind. If I have questions, I can text him, and he responds. He goes out of his way to help. My family and friends are amazed at the improvement in my Cervical Dystonia. Dr. Troung is so busy traveling around the world teaching other countries about movement disorders and writing wonderful books, but he still takes the time to handle his office appointments. He's a miracle worker and I adore him. read more

Seeing my spouse for Parkinson's but never listens and ignores new information about physical therapy and speech therapy. Keeps changing medications for her. He can be rude and dismissive if we question his logic. I haven't seen much improvement over the past few years and need to consider her seeing a more progressive specialist. Her walking is not improving. I think he's egocentric and doesn't want to consider newer research into Parkinson's. read more

Needs to have receptionists RE-trained. No talk, no thank you, no please have a seat we will call you. Stood there like an idiot waiting for nothing as that lady didn't say a single word besides "I need the insurance card". Handed it to her, returned without a single word. Sad... read more

Dr. Truong is horribly rude, he won't let you talk!! He treats every patient the same way... I wish I could give this place and Dr. Truong Zero stars..... he made my mother suffer for 6 months all because he wasn't willing to listen. Shame on you read more

Dr Truong has been treating my facial dystonia since 2009. It took me ten years and just as many doctors before I was referred to Dr. Truong, he took one look at me and knew what was causing my symptoms. He literally wrote the book(several books actually) on dystonias and how to treat them. Dr. Truong travels all over the world teaching other doctors how to treat this affliction. Although he is very busy he never rushes my appointment, he always listens to all my concerns and answers all my questions. He is sweet and I trust him completely. read more

This office is a joke. I came here looking for answers I still have none. MRI shows lesions in my brain. Along with other neuro conditions most of which point to MS. I was put on a tremor med and told to cone bck for follow up. Can't get in for 3 mths. Still don't know my condition or why I have lesions. I saw dr. Troung Nguyen he is aroubd 80 and should not be practicing anymore. read more

I had to wait two and a half months for my appointment with him, and meeting him was a disappointment. He told me he does not treat my symptoms and referred me to another doctor; why would you take my appointment and make me wait so long only to tell me to go to another doctor? He was rude and yelled at me to get out, even after I accepted seeing the other doctor. He needs to learn how to speak with patients politely and nicely. Horrible doctor. read more

Is not completely informative with his patients, by that I mean does not let you know about other alternatives for your symptoms.

I have been seeing Dr. Troung for several years for spasmatic tortacollis/cervical dystonia and chronic tension headaches. When no one else could help me Dr. Troung gave me back my life. I now live pain free. He is kind, professional and the ultimate best in his field. He is a true blessing. read more

Seventeen years ago it was very difficult to find a neurologist who understood spasmatic tortacollis/cervical dystonia or even was able to diagnose it. I was told it was all in my head and to learn to live with it. This disease is quite constantly painful and difficult to tolerate. One visit with Dr. Truong brought a diagnosis and the beginning of treatment which allowed me to restart a fulfilling life style. Miracles happen, and this one began with the help of a dear and kind man. I thank you Dr. Truong, you hold a special spot in my heart. read more

Dr. Truong's compassion and care about his patients is exceeded only by his amazing talent and intelligence. While working for big Pharma I first met Dr. Truong as he is one of the best investigators and speakers on new drugs. Eventually, I became his patient as I developed a very serious and painful movement disorder. At the time I was living on the East Coast and went to innumerable doctors and got no relief. Thankfully I came back to So Cal and got to see Dr. Truong. Words cannot express my gratitude as he changed my life. Quality of life came back. I could be active again, socialize and be pain free. He has totally restored my ability to live a normal good life once again. I have known him professionally for over 20 years as an author and world renown clinician and I have been his patient for 12 years. He is amazing. Don't live in pain and embarrassment and depression. I highly recommend Dr. Truong. I thank him and I thank God for him being the outstanding doctor he is especially when treating movement disorders. Debi N. read more

Dr. Troung has been treating me for hemifacial spasms for the past 20 years using botox therapy and he literally wrote the book Botulism Toxin Therapy, so as a patient with a movement disorder one could not find a better nor more capable neurologist. He is a very personable, kind doctor who listens to everything I want to say without hurrying me and allows time to answer any and all questions. I thank God my MD referred me to THE VERY BEST NEUROLOGIST. K Lamb read more

BEWARE! Office staff takes no responsibility for their mistakes nor do they accommodate when they've made one. When changing one of my appointments, they cancelled all of my appointments. Even after I got a confirmation call. Saying that I never had an appointment in the first place. Not even asking me if I want a new appointment just telling me that the neurologist was too busy to see me. read more

Dr. Daniel Truong has been my Neurologist for 30 years. I credit Dr. Truong for being the only doctor who has cared for me & many others for Our RARE Incurable Disorder. He has often called my home after treatments to make sure that I was ok & not having any adverse side affects. His staff are always very helpful & personable. He is always putting on Symposiums across the U.S. from East-coast, to Mid-west, to West-coast so that everyone can have the opportunity to attend without putting out allot of money to go so far. He is now known internationally with his continued Learning, Teaching & his Practice. My condition is so rare that the 1st. time I met somebody else with my Disorder was when I attended my 1st. Symposium. I can never Thank Dr. Truong enough for what he has accomplished with me. I was in sooooo Much Pain, I just wanted to Die. He saved me & my family from devastation. read more
