I visited the new Padre Island nautical theme location last week which is so beautiful and clean but more importantly state of the art. A+ rating to the Island Medical Office NP and staff and I personally recommend Martinez Medical which I believe does have (5) area coastal bend locations. Their in-house lab and diagnostic services is a bonus but think about trusting your care with a professional team that truly has your best interest. Most insurances is accepted but also cash pay services which serves everyone and anyone!! I am so happy that I did schedule my annual exam with Dr Mario Martinez MD & team.

I was impressed with how thorough and patient he was with her, so I made an appointment with him and have been his patient ever since. If you see Dr. Oloyo, you will receive top-notch, comprehensive care. He is patient, kind, thorough and tremendously knowledgeable. He makes it a point of asking detailed questions and of LISTENING to what you tell him. He has the ability to manage multiple and complex problems that a patient may have, and he demonstrates genuine care and concern I encourage you to go to South Texas Medical Associates. You will not be disappointed.

He also put his dirty hands...didn't wash between patients, used dirty stethoscope....all over her face for no reason. He also looked on the front of her stomach for her nephrostomy tube hole-a dr that doesn't know this is on the back should not be in business! She had to spell out then write down how to even spell Nephrostomy to the nurse. We waited two hours to be seen and he didn't listen to her at all, kept cutting her off. He only cares about money. Glad she is reporting him for negligence. His er and primary care clinic need to be investigated. I think he is committing fraud. I also think this is a great place to go if you want the FLU OR CORONA VIRUS SOON SINCE HE DOESN'T WEAR GLOVES OR WASH HANDS BETWEEN PATIENTS!

Mackrizz/office somehow left 2/3 medications off my prescription order. For the third medication, he ordered two of the same medication...at the WRONG dosage. This was AFTER my third call to his office to have Rx corrected. I just called a 4th time...this time I was noticeably short of breath because his office has still NOT filled my beta blocker Rx. I also learned that according to a specialist I saw, Mackrizz orders unnecessary tests. Tests insurance won't pay for...yet that I must pay out of pocket. It feels like either incompetence or egregious malfeasance. Doctors who "test everything" then bill insurance increase their profits while making insurance unaffordable. My wife, a CRNP, even re-coded inaccurately coded testing so insurance will pay. She gave Mackrizz's office the corrections. They still dropped the ball. I suppose if I had zero inside baseball, I'd just write a review about how he was nice. Nice is great and all. But.... I also feel he misdiagnosed me with asthma and ordered asthma medication I didn't need that insurance didn't cover (Brio-$90). He had this Fisher Price looking device that he (surprise) charged extra to test with. Another $100. I saw a pulmonologist daily for 2 months in an ICU. A year later, I followed up with a second pulmonologist. Respiratory specialists don't diagnose me with asthma after EXTENSIVE testing--yet a Doctor of Osteopathy diagnoses asthma? I understand the numbers were lower from one test to the next. I feel it wasn't about the "respiratory test" but about profitable testing. Furthermore, Mackrizz diagnosed me with hypertension. Same deal-- a specialist I saw many many times--a cardiologist--doesn't diagnose me with HT--yet Mackrizz diagnoses me with HT? My experience with Mackrizz is that he ordered unnecessary tests, that while profitable for him, cost unnecessary out of pocket expenses that don't solve problems I don't even have! He knew there would be charges his office would bill insurance for that insurance wouldn't cover. As soon as you walk in his office, signs preemptively & boldly state this. Clearly, it occurs with enough regularity to create signage. He was nice though. And charming. And seemed thorough. When I complained about the two-hour wait and how I was barked at by a member of his staff for complaining about a two-hour wait he seemed empathetic. But I'm stuck with--maybe $1000 of out of pocket expenses, two incorrect diagnoses, and can't get my prescriptions filled after a visit and multiple phone calls?

Best of all I have been cancer free for nearly 25 years now. Sure, I had some long waits in his office but I have also had many long waits in other doctors' offices. I never found Dr. Perez rude nor not concerned about my health. Having come from a medical family, worked in hospitals while in college, Doctors often have emergencies come up that keep them in their hospital rounds and away from their offices for longer than they would choose. It is better to wait and be seen than have to reschedule for maybe several weeks on down the line. Remember, cancer doesn't wait.

Do NOT waste your time or money here…read more Let's begin. I randomly began experiencing some back, abdominal and side pains with severe nausea. I was checked out by my job's on site medical staff and advised to see a doctor as they thought I may have kidney stones. I am not from the area so I don't have a GP here nor am I familiar with any of the hospitals or clinics. I searched for providers in the area who accept my insurance and this one came up so I made an appointment. I was asked to arrive 10 minutes early to fill out paperwork. Upon pulling into the parking lot I was immediately a little turned off by the huge "BOTOX / WEIGHT LOSS" signs slapped on the building. Where I'm from, only tacky doctors offices do that kind of advertising. But I don't know this place, so no biggie. It got even tackier when I walked in. This doctor has done-up pictures of himself along with praise articles slapped across the wall and is even advertising his vacation rental homes in his office... you can't make this up. Pictures attached. I walked in 10 minutes early and wasn't acknowledged or called up until 15 mins AFTER my original appointment time (12:30) I filled out said paperwork, and then waited for another full hour to be called back. I was asked to wait in the patient room for ANOTHER hour before even being seen by the nurse (2:30). I asked when she thought I might be seen by the doctor as it had already been 2 hours. She responded with a snappy "she's coming". Ok. At 2:45 I'm told they'd like a urine sample, blood sample, and ultrasound. Perfect. Those simple things took until 3:45 (lots of waiting in between) and when I was done they sent me back to my room that they had already put another patient in. I accidentally walked in on him. The doctor came to discuss the findings with me and said they didn't see anything but she was still writing me antibiotics (?) and pain relief in case there were stones that they couldn't see. I make mention of the pains and their randomness. No questioning is done and she insists I get the meds. I ask when I can see my lab work results. Surprise! There is no portal and they have to give them to you in person, requiring you to return for another shitty appointment. Cheers I left at 4:15. 4 hours for what could have taken 2. I won't be back. Upon looking up this doctor's other office (on Saratoga) I saw another slew of horrible reviews. Save yourself the time.
