Patient Testimonial
Posted on Verena SedilloTrustindex verifies that the original source of the review is Google. A great visit with Dr Messiha. Prior to my treatment he asked me a lot of questions concerning my pain to gain an understanding. At my treatment he described exactly what he was going to do and what to expect afterwards. I liked him very much and hope for positive results.Posted on Pazit BenezriTrustindex verifies that the original source of the review is Google. What a great team and service. The communicate very clearly, help me to make sooner appointments, email documents and was super refined and patience with us. If you have option to get service from them rather than anyone else I would absolutely choose this place!Posted on Charlene SorensenTrustindex verifies that the original source of the review is Google. Professional, explains everything in detail, is very caring, and attempts to take care of the situation with your back pain,Posted on Margie DiazTrustindex verifies that the original source of the review is Google. WOW. I am writing this for my wife. She had been suffering for 6 days. I had never seen her in such pain. We went to the ER, we saw her primary doctor, we saw the primary doctor referred physical therapist. The pain center the primary referred to was booked for the next 3 days, and every place I called was also 3-4 days out. Then a friend recommended Dr. Messiha. He made the effort to make the time, and saw before the end of the day. By the end of the appointment, for the first time in almost a week, she was not in tears. After all that, I would never consider going anywhere else. From Miriam that walked me through the inevitable paperwork for a new patient, and answered all our questions (we had never been to pain specialist before, and had no idea what to expect), to Gina that quickly checked us in on arrival, Daniel who took her vitals and then later assisted Dr. Messiha with the procedure, and finally Mary Anne with the follow up appointment and helping me get everyone’s name right! WOW!. Then there was the doctor himself. If my wife had not been in such pain, I think the apprehension would have been almost overwhelming. But Dr. Messiha, calmly, and clearly, laid out all possible expectations, reassuring her, and explaining everything. When I saw her again after the procedure, her pain was more than 2/3 gone compared to what it was going in. And each day has been better than the day before. She is almost pain free. I could not recommend him and his staff more.Posted on TheHuman CollectionTrustindex verifies that the original source of the review is Google. Absolutely the worst experience I’ve ever had with a medical clinic — avoid this place at all costs. They falsely billed me $65 for a co-pay I already paid on the day of my appointment — and they wouldn’t even let patients in without paying first, so the charge made zero sense. I spent over a year and a half (18 months!) trying to resolve this issue, sending proof from my bank account, calling and messaging repeatedly, and getting ignored every single time. The front office staff promised multiple times that Mary Ann would follow up, but she never once reached out. I was completely dismissed and stonewalled, while they continued to send threatening payment letters to my home as if I hadn’t done everything to prove my case. When they finally responded 18 months later, they blamed a “bad billing company” — but that doesn’t excuse the total lack of accountability, transparency, or even basic communication. I wasted hours trying to fix their mistake — taking screenshots, writing messages, calling, and being ignored. To make things worse, the treatment didn’t even help, so not only was my time wasted on the medical side, I was left fighting a nightmare of a billing system that clearly doesn’t care about patients. I would never set foot in this clinic again. The way they treat patients — both medically and administratively — is beyond unprofessional. Save yourself the stress, money, and time. Go anywhere else.Posted on DanTrustindex verifies that the original source of the review is Google. I have been a patient of Dr. Barnhill for 3 months now. I’ve been in severe pain for over 10 years now, due to spinal stenosis and failed back surgeries. Of all the other pain management Drs I’ve been treated by , Dr. Barnhill is by far the best. He is very knowledgeable and has all the tools available to help with pain. I’m on a new medication now and it’s difficult to navigate. He is doing a great job following up with my progress. We have decided not to do anymore injections for now because they haven’t worked in the past. Instead we are going to do the spinal cord stimulator. His office staff is very professional and they are helping me get the trial approval from insurance. I still have hope for less pain and I feel I’m in the best hands possible. Highly recommendedPosted on Ashley MarieTrustindex verifies that the original source of the review is Google. Dr Andrew was 35 minutes late and sat with my husband for all of 15 minutes making him feel like a speck of dust that he could not be bothered by. My husband is a combat veteran and came home from speaking to this doctor in tears because of obvious discriminatory antics of my husbands past. My husband can barely pick up our 11 month old daughter without wincing in pain and this doctor had the audacity to even question his combat experience and the pain I personally forced him to get addressed because his quality of life has been decreasing more each year and he needs help. You should be ashamed of yourself for how you treated my husband. This doctor is the reason we have such a healthcare crisis in this country. I work in healthcare and this type of behavior and blatant mistreatment is exactly why people do not seek care and turn to not so savory things to find relief. I am appalled and truly disappointed that this doctor came recommended at all.Posted on Alyce BrittonTrustindex verifies that the original source of the review is Google. If all offices, staff and doctors were like Dr Messiha’s, the world would be a better place!! Responsive, caring, excellent education and listening skills. Highly recommend!!Posted on Michael SalehTrustindex verifies that the original source of the review is Google. My father has seen nearly a dozen doctors over the past several years for his knee and leg pain. Beyond the pain medications that he was prescribed, he’s had cortisone injections, gel injections, acupuncture, and physical therapy—but nothing worked to ease the pain. Over the past six months, the pain increasingly worsened and his condition progressively deteriorated. He walked independently a year ago, but lately he walked hunched over, needing a walker and the help of a family member to ensure he didn't fall. A doctor felt that my father might have spinal stenosis, and he was referred to Dr. Messiha to administer an epidural. Dr. Messiha’s calm demeanor was immediately reassuring (and his office staff were friendly and accommodating). Dr. Messiha expertly targeted the source of the pain. My father said that the epidural injection was essentially painless, which surprised him, and Dr. Messiha was pleased that he could see the medication had spread nicely throughout the area that he was targeting. Dr. Messiha said that my father should feel the full benefit of the epidural after two weeks. But after just one day, my father has experienced a remarkable reduction in pain. Now he’s walking fully upright, without his walker, and without the assistance of anyone else. It’s unbelievable! We can only thank Dr. Messiha for relieving the pain my father has felt for many years. We wholeheartedly recommend Dr. Messiha without any reservation.Posted on Joseph BroderickTrustindex verifies that the original source of the review is Google. I have been working with Dr. Messiha for about six months now. I returned from Europe in mid-October, afraid I had aggravated an issue that would limit my ability to continue my work, hobbies, travel, and retirement. Dr. Messiha's treatments have helped me re-establish my ability to enjoy life and perform my normal work functions. Dr. Messiha’s staff is highly professional and ethical and works with my spine surgeons. Together, we are crafting an individualized plan that is all-encompassing for my long-term care.Load more
