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.

They take ages to do almost anything. I went to him mainly to get a prescription filled because my…read moreprevious doctor stopped taking my insurance. By the time they did my blood work and stuff it had already been a week and I had run out of my medication. In the end it took them around 11 days from when I had the appointment to getting my medication. One time I called to have my prescription sent to a pharmacy and it took them 6 days to call in my prescription. Because of the laws surrounding my medication, I could only have it filled three days before I run out, causing me to go three days without it. This is after I already did all of my blood work and in-person appointments, so all I had to do was call them to get the prescription sent. Sometimes when you call and explain your situation, they place you on hold for so long while they do something that a different person picks up the phone and you have to explain the situation all over again. A few times I was on hold for so long that it went to their lunch time, and then I was immediately hung up on without talking to someone for over 10 minutes. Then I would have to wait 2 hours for their lunch break to be over. Having a 2-hour lunch break is already ridiculously long. If you want quick, effective, and professional care, then avoid this place like it will give you the plague. Judging from other people's reviews, it just might

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.

Going on 3 months-Mackrizz/office still hasn't filled my prescriptions correctly. Multiple…read morecalls...for three medications I've been on for several years. 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?

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.
