Before my son's first appointment, they called to say there was a situation that arose with my insurance. I was able to get it taken care of before we got there. When we got there, they talked to my son and I for a good amount of time before the tests even began. I was thankful for the wonderfully caring staff that helped my son with his tests. I'd happily refer anyone else to his office!

For more than two decades he had been the dependable go-to-nurse in a government hospital tending to mentally disturbed patients. Since last year our son's health suffered as the cumulative effect of a punishing work condition such that he needed medical care himself. Unbelievably, Los Angeles, California, with all its reputed cosmopolitan advances and progressive pretensions, proved direly incapable of providing satisfactory medical care when needed most. It's either that doctors don't service my son's insurance coverage or that their schedules were top heavy and for many other reasons. The couple of medical providers we ultimately contracted had their own sweet times of when to engage a patient such that there were emergency situations and they would not even pick up the phone. My son's employer also has doctors but they, too, were found wanting. My wife and daughters would take turn pleading, crying over the phone asking office staffs to connect then with the doctors, to no avail. There was someone we had been addressing as "Doctor" for sometime only to find out that he's a nurse practitioner. There were instances of seriously wrong medications prescribed resulting in my son's ailment turning worse. A Texas-based daughter brought to our attention Dr. Robert Hernandez of Primary Medicine of Sherman and, boy, he's heaven sent as far as we are concerned. In the words of another daughter, Dr. Hernandez is a doctor who cares, the kind of Primary Care Physician we're looking for his brother and everyone in the family. Laymen that we are, we, nevertheless, are capable of discerning the wide chasm of difference between our sad experience with California's medical world viewed in the prism of Dr. Hernandez' humanity, very capable hands, and sincere care of patients. Friendly office staff, too. As a matter of fact, we're in the process of resettling in this part of Texas so that everyone in our family can avail of Dr. Hernandez' care and expertise. I'm sure this is only the first of our shared observations for the benefit of everyone in need of competent, patient-oriented medical provider. At our first meeting with Dr. Hernandez, we feel that he was not just a doctor of the body and mind, but of the soul, as well, because he reaches out to our deepest longing for a friend, a confidante and someone akin to family, who we are not afraid to share our deepest fears and anxieties with. We feel safe with him both physically and emotionally, confident that he is someone who will be there for us. We look forward to more productive and more meaningful association with Dr. Hernandez and we wish many more will come to know him, as well. We certainly are not putting any pressure on the good doctor with unreasonable expectations because we know that all patients at Primary Medicine of Sherman are being treated equal. We just want him to know that we are grateful for all that he has done for our family. Thank you, Dr. Robert Hernandez!

My wife and I have used Dr. Tann since 2019. We really like her and she is very professional,…read morecaring and likeable. HOWEVER, as the DFWPMA group grew, they have failed to keep reliable, efficient office help. I needed to see her once thinking I might have a kidney infection. I was told she was on vacation by whom ever answered the phone. I told them my concerns and was told she would check with the nurse and see if another physician in the practice could see me and I would be contacted that day (Wednesday). By Friday, when I still hadn't heard from her office I went to Red River Emergency Hospital and was seen. The following Monday, I got a call from Dr. Tann's nurse asking if I had a problem. JUST a little late. My sister-in-law needed a follow up mammogram and TMS is the only place in Grayson Co doing those now. Dr. Tann's office was supposed to order that procedure but it took three calls to her office to get it ordered. She and her husband also had 6 month routine wellness labs performed and were supposed to be called with the results. 3 weeks later, they still had not heard the results. My wife was prescribed an anti-depressant which she had taken in the past. The pharmacy substituted a generic for the name brand. After taking a weeks worth of the medicine, she had trouble walking and was more despondent than before. I stopped giving it to her and the problems cleared up. Several weeks later we had a televisit by Dr. Tann. She advised to try the medicine again. We did with the same results. We once again stopped it and the problems cleared up again. Upon informing Dr. Tann, she said she would re-prescribe the medication and tell the pharmacy to use name brand only and if there was a problem to let her know. We got a message from the pharmacy later that day that not only was her generic medication ready but that the Dr. had prescribed a 90 day supply. This was on a Tuesday. I called Dr. Tann's office and told whom ever answered the phone of the problem and was told the nurse would get back to me soon. As of today, Saturday, we still have not heard a thing from Dr. Tann's office! I really like Dr. Tann herself and want to keep using her, but, the office or nursing staff in either overloaded with work or is totally incompetent. Personally, I think that the Group has grown too large, too fast and hasn't paid enough attention to base structure. I would give Dr. Tann, herself an A+ but her office staff/nursing staff an F-!
