Dr. Mario Martinez M.D., internal medicine physician, is incredibly thorough with his medical assessments, knowledge, and is very up to date with all of the latest therapies and treatment options. 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. read more

My husband went on Feb 2026 and ended with a phone call letting us know they found something in his blood work but we had no funds for another copay and we explained the situation and they still stated they could not do anything for us. Its been over three weeks and I finally got his blood work through the app. Now tell me why can't the doctor submit medications to our pharmacy. Wow! This doctor really cares for his patients. Never again. No thank u. read more

I was a patient of this practice for almost 4 years. For about 3 years, I tried to be seen directly by Dr. Mario Martinez at his Portland location, but I was never personally examined by him. I was always seen by a nurse named Jennifer Contreras, who is an APRN and legally works under a physician's license and supervision. She stated that the doctor reviewed my case and made decisions about my medications and lab work, even though he was never present. About 5 months ago, I located Dr. Mario Martinez at his new clinic in Corpus Christi, where he was finally seeing patients in person. Despite having many previous tests, he ordered many more studies. At my follow-up appointment, he told me I had cancer. I broke down in tears and asked him twice if there could be any mistake. He said with absolute certainty that I had cancer. He also told me that I would not be treated in the United States and that I should go to Mexico for treatment because doctors here would not accept me. My daughter asked if that would still be the case even if I paid, and he said yes. He gave me lab results written in medical terms that I did not understand. I sent them to two of my nieces who are physicians in Mexico, and they both said the results did NOT state that I had cancer. They consulted with a colleague in Canada who also confirmed that there was no cancer diagnosis in those reports. The reports only indicated that further examination of a thymoma biopsy was needed. My hyperthyroidism can explain the thymoma enlargement. I cannot understand how a doctor can state something so serious with such certainty without confirmed evidence. This caused me severe emotional distress, fear, and psychological harm. Today, I went for a follow-up appointment for my hyperthyroidism. I was told I had to pay extra for using a credit card due to a new percentage fee. I was never informed of this change. Legally, credit card processing fees are a business expense and should not be transferred to the patient without proper disclosure. When I questioned this, Dr. Martinez came to the front desk visibly angry and stated that he was charging me the fee because the bank charges him 5%. When I explained that I previously owned a business and that this fee should be covered by the merchant, he raised his hand in a silencing gesture, turned around, and walked away. After almost 4 years and thousands of dollars spent, I feel deceived and disrespected. I do NOT recommend any clinic, office, or medical provider associated directly or indirectly with Dr. Mario Martinez, including staff working under his medical license. Although he is Hispanic, I felt discriminated against as a Hispanic patient. In my 35 years living in the United States, this is the first time I have ever felt treated this way. Giving a false and alarming diagnosis and suggesting that I seek care outside the U.S. caused fear, anxiety, and emotional damage. This doctor lacks professionalism, ethics, empathy, and proper patient care. Patients should not be humiliated, dismissed, or frightened with unconfirmed diagnoses. I strongly recommend seeking care elsewhere. read more

Worst experience with a doctor in 40+ years with 3 kids. Dismissive, claims to be an "internist" but lacks basic knowledge of some less common conditions, his cell phone was going off the entire appt- he answered calls and read/responded to texts. When I expressed frustration he threw his hands up and said he couldn't help me, and then refused referrals claiming I would never find or get into any specialists here without waiting 6 months to a year. My husband asked for the referrals for me, and was able to get me appts with every single one we needed within weeks. Never could get a copy of my blood work though I've called and made written requests. Oh, and at the end of the appt he said "what else? That's it? Good." And got up and walked out, clearly unhappy with us. It was very disheartening as we had just moved here and were hopeful for a competent provider nearby.., needless to say: he is NOT THAT. I was shocked with not only the lack of knowledge and professionalism, but with his lack of basic common courtesy and compassion as someone in the medical field. (Also note, he definitely gives off male chauvinist vibes, and I have no doubt that had my husband not been with me that it would have gone even worse.) read more

The absolutely the worst "dr" I have ever been to. If you speak Spanish and pay in cash, this is your place.

If you're looking for a great way to beat the Texas Summer heat, look no further than to talk to the girls at the front desk of the Saratoga office for Dr. Mario Martinez, as the front desk girls have ice water coursing their veins. Literally the worst customer service I've ever seen in my life. I sat in the waiting room, watching a lady have absolutely no empathy for the sick people, making unnecessary hurdles regarding insurance cards ( & in callus manner none-the-less) and I heard the girls talking about shoes (size 7) instead of paying attention to the people standing right in front of them. I also want to mention that the doors were not open by 8 AM instead by 8:10 and by then there was a line of people lined up- mind you a lot of the people are older, sick and obese.. and the girls inside did not open the door and invite people in to let people know that the doors were unlocked when we were well aware they heard the doors jostling since it was 8AM. Very funny. T let the people stand there, sweating and ill until they figured out that they had to pull on the door again to be let in. No manners. The only time I ever saw smile from the girl in the front was when a woman walked in containing everybody's frozen coffee for the morning. The ladies at the front refused to give the phone number to the office on Greenwood, and instead said that they would have to look it up themselves. Ridiculous. There are a lot of people looking for jobs right now, and if you are not happy to be working where you are find a new job, but do not make people who are already suffering and sick suffer some more with your foul attitude and poor manners. read more

I got there at 1 PM and had an appointment and never got seen and I walked my self out at 4 pm and no one ever helped me except for the girls at the front read more

We have been waiting over an hour and still haven't seen the doctor. The music is weird and way too loud in the lobby and throughout the office. read more

please save yourself sometime and find yourself a different MD. This low excuse of a MD, is very very Rude and Unprofessional. Him as well as his staff are a bunch of incompetent medical team. Do yourself a favor and look up his reviews !! If you care about yourself go and schedule with a different Dr because you'll only be charged by him not see him either. read more

Hands down the best primary MD I've ever had. Several locations, nice facilities. Dr. Martinez and his staff are top notch. read more

office staff almost never answer the phone so you have to walk in to be seen and you wait for hours to be seen. I need to get a new doctor

Office staff is disorganized and possibly incompetent. Phone messages are never returned. On a recent visit I was given a new prescription - you have to return to the waiting room and cool your heels while it is generated. After waiting what I felt was a reasonable time I asked reception for a status report and had the prescription within a few minutes, They do not accept checks. Whenever I call for an appointment they encourage me to just to walk in. which works well normally. Today I walked in 40 min before closing and they refused to see me citing closing time. They were not busy. Don't expect to see Dr. Martinez -you will be flogged off on a nurse practitioner. They do accept Medicare. read more

Horrible experience there a few years ago. The doctor didn't even look at the chart and performed a service I did not want then wanted to charge me for it. He was rude and unapologetic. I felt trapped because I had paid already for another service, and just wanted to get it over with and get out of there. His staff member knew what had happened but seemed intimidated as well. I understand that he is opening a facility on the island. Explore your options before going here. read more

Horrible choice. His staff is the most incompetent people I have ever encountered in any medical office. Definitely, don't waste your time there. Find a professional doctor. read more

I received botox injections (50 units) during one of their promotions. This botox was TERRIBLE (ie. One of my eyebrows would raise afterwards and the wrinkles at the center of my forehead never went away...and I should add that I'm only 31)! I've since had it done by a reputable plastic surgeon and the results were NIGHT and DAY. Do not waste your money on botox with him. Even though it seems like a good deal, it's drastically diluted and you'll be forced to go elsewhere and pay more anyways just to fix the botch job! read more

The worst staff I have ever had to deal with. Cannot read the paper work from the Doctor or the NP, lies to the patient about setting up referrals, will not listen and very arrogant. Only concern they have is how much you owe! Dr. Martinez has been professional, but really needs to follow up with the staff. I have a rotary cuff tear and was referred to a vascular DR, for my foot?Hope he will stop hiring girls that only have experience from the McDonalds front counter and no other skills. Terrible choice !!!!! read more

Dr. Martinez is very kind and thorough with his examination. He was very reassuring and even gave me some extra tips about skin care while I was in for my health exam. Awesome that he has so much knowledge about both! read more

This office is most unprofessional place I ever been. I asked for me & my wife's medical records and it took 2 trips to that office to get them And to make it worst they charged me $50.00 for them. All my other doctors give my records for free and say that its against the law to charge for them. All this office wants is Money Money Money. Look up this doctor you will be amazed read more

Materialistic Jerk. When you walk in no on greets you, instead, the sign in sheet was shoved at you. Obviously she was too busy to speak. I get called back, and was greeted by the only professional and friendly person I encountered, she takes down general information about your health background. (the doctor should learn how to behave from her). Then the Nurse Practitioner came and asked basically why I am there so I explained to him what is going on. I did state "I prefer not to take any medication if it's not necessary, but if you feel I have to I will take what you recommend." (obviously I am not a doctor and don't know how serious or not my situation is) Would you consider this an unreasonable statement? I think not! He left to discuss with the doctor and after a while they both came back. The doctor walked in (no introduction) and sat down and said "What is the problem?" Before I opened my mouth he said, "Never mind, I know what's wrong." Stood up and walked back and forth and stated in a loud firm disrespectful voice, "YOU ARE BEING RIDICULOUS, you saying you don't want to take any medication we give you is ridiculous." I couldn't believe my ears, first of all he is getting second hand information I haven't even spoke two words to him. I felt like I was on trial and had to defend myself. I restated what I said before that I PREFER not to but if I have to I would. How is that saying I will not take any and I rather suffer? He then proceeded to go on and on how the only people who want to take medication are drug addicts and other non sense. I felt like I was in the scene from Matilda "I'm smart; you're dumb; I'm big, you're little; I'm right, you're wrong, and there's nothing you can do about it." - Harry Wormwood. An x-ray was recommended. Even though I was upset/disgusted/disappointed in my visit I figured why not I am already here. The person who took my x-ray was very unprofessional he was on a personal phone call and instead of explaining what I needed to do he would grab me and move me and even grabbing my head where he touch my lips! So disgusting!!!!!! I regret not reading reviews from www.ratemds.com and coming here on a recommendation from a friend. This certainly taught me to do some research beforehand. I will not be returning. read more

I made an appointment to refill 2 prescriptions. The front desk staff and medical assistant seemed nice enough. I saw 2 different PA's. The first one was nice and straight to the point. The second seemed to think I needed a thyroid and heart ultrasound. Wtf? I'm all about preventative care but seriously? I didn't need either of these procedures. The waiting room was packed and I waited 45 mins to be seen and that was with an appointment. Jeez. I don't think I'll be returning. The staff seems stressed out and unorganized. read more

i would never recommend this place. they do excessive, unwarranted testing, such as an ekg, ultrasound of veins, and xrays out the wazoo...for an upper respiratory infection. i have yet to see the doctor, only nurses, or nurse practitioners. i have been sick for over a week, had a flu test, and blood work, and not one person will call me to let me know if i have the flu or not. you go in and sit for hours. you have an appointment at 9:00 a.m., and arrive at 8:45, but someone with a 10:00 am appointment shows up at 8:40 am, they call that 10:00 am. appt back first, and that is wrong, defeats the purpose of an appointment. i am furious with the lack of moral compass this so-called medical practice has. read more

The worst place I have ever gone to!!! I went in March for the first time to do facial laser hair removal!! All I get is dark spots in my face (they burned my skin) and the hair grows more now because they shaved it!!!! Please DO NOT GO THERE!! When I told them they told that I signed a paper that it is ok if I got burnt!!!!!!!!!!! read more

It is always a positive coming in to see Dr. Mario Martinez and his staff. I have searched high and low to find a Dr who actually listens to his patients. I am always treated with positive and encouraging words as well as 5-star treatment! read more

Doctors and staff are way to over booked to be an affective place. If you make an appointment be ready to be there for hours upon hours. Regular checkups take three to four hours easily. They also over test patients to run up the bills and over charge the insurance. These place is horrible to get anything done. I came in for a sinus infections and had to get four X-rays and breathe test for lung capacity. I am surprised they didn't ask for a colonoscopy, blood draw, and ultrasound of my appendix. It is crazy how these place works. Do yourself a favor and find another doctor. This is the last time I come to this place. read more

People in this office should really learn basic manners. Literally the worst place to get treatment. They over charge in every possible way. The waiting time is so long, that you will have to cancel any other plan you might have for that day. Moreover, I have yet to see the doctor, only nurses, or nurse practitioners. read more

Dr. Mario office is ok. I like coming here because you can walk in without an appt up until 3:30 pm plus I dont have to wait 2-weeks to see a doc when I have the flu. read more

Great experience....was really worth the wait...he took care of my wife very professional worked with our budget and we will forever be greatful. I have been a patient @ the staples location for 3yrs and never met mr Martinez..today I had the pleasure of meeting him.. .. Staff was incredible and very professional...ps she was a walk-in read more

Absolutely the most poorly run medical office in Corpus Christi. If you want a refill of prescription they make you wait HOURS to be seen and then you have to come back ANOTHER DAY to get the prescription. Homeless people don't have time for this place. DONT GO. read more

Dr. Martinez is very arrogant and has a terrible manner. When I saw him, he would not let me talk about my symptoms and kept cutting me off. The music in the building is too loud and annoying especially when your head is hurting. The girls in the front desk do not acknowledge your presence even when you are standing in front of them for several minutes until they feel ready to speak with you. The nurse, phlebotomist, and X-ray tech were very nice and warm. The building is very beautiful. Walking into the building, there was a Lamborghini parked smack dab by the front door, bigger than life. I asked a girl at the desk and she said 'that's one of his many cars'! It sat there, like a big flashing sign to his patients, some who struggle to meet the price of insurance premiums, co-pays, and deductibles just to see him for 5 minutes after waiting 4 hours. read more

I called this ofc after my wife's eye doctor recommended them for a general physical exam.They said if would cost $125.We arrived at 11 am and waited 2 hours to be seen.Then a nurse practitional named Joe saw here.He then spoke with Dr Martinez and they said they would NOT write or sign a letter without doing a series of expensive additional tests(in their lab next door of course).They said they HAD to do a "Clearance for surgery"letter.My wife's eye doctor's assistant tald them "NO,all we need is a routine physical"They would not listen.After 5 hours of wasted time(they charged us the $125 up front),my wife left frustrated with zero information.I spoke with DR Martinez by phone from home the same day.He was obnoxious,to say the least.He said"MY REQUIREMENT is that these tests be done or I won't sign".I feel we were ripped off and intentionally misled by this office.People there are rude,especially Dr Martinez,and not at all patient oriented.Terrible,terrible! read more

I took my neighbor there for her appointment and the first think you notice is the televisions in the lobby are loud and on FOX news. This was the day before the Presidential election and the jabber on tv was very negative and hateful, and I asked if they could change the station to something light like "The Price Is Right" or something. The receptionist was very nice and professional but apologized that she could not. When we got into an exam room, the first thing you notice is the blaring music. It's like stripper music and very very loud. My elderly neighbor said he always turns down his hearing aid when he comes here. Once again, the exam room had FOX news on and it was more talking heads spewing negativity and hate, I asked the nurse how we could change the channel to something light-hearted, and she said: "Dr, Martinez is a Republican and he has ordered that every TV be put on FOX NEWS today and tomorrow at every clinic, she says he owns four! We waited for him for 2 hours and saw a PA and saw Dr. Martinez for 4 minutes (I timed it). He is not a good listener at all. I had to remind him several times what the patient was asking him. My neighbor says he does not like coming there because of the music and when he comes by himself the front staff is not very helpful and I notice that they pretty much never look up and ignore people rather than greeting you with a welcoming smile and telling you they will be right with you. They talk to you while not looking at you. The nurses are nice. I will work on an alternate choice for physician for my neighbor and report all this to his insurance company and hope they can help me find him another physician. Oh, yeah, and the previous reviewer is correct, you cannot help but spotting the Lamborghini parked practically at the front door Disgusting display of wealth. read more

I went to Dr. Martinez' office because the nurse practitioner I had been seeing since 2013 moved to this practice. I have to refuse to see the other Physician Assistants in the clinic just to see her. I had established rapport with her for almost 2 years until she moved. Wish I had read the other reviews before I went to this office. First visit was definitely a see how much we can get her insurance to pay. When a test was not covered, they did not tell me this. They said they were waiting on prior authorization. I had to ask if prior authorization was ever received. No one listened to my heart or lungs or looked in my nose or throat. Had sinus and lung x-rays. Told Lisa Olivarez that the antibiotic she wanted to prescribe no longer worked. She said the doctor only allowed them to prescribe a few medications and the one I wanted was not on the list. I fought until I got the medication I wanted. Only the CMA that takes vitals ever has hands on approach to medicine. It is all about labs and testing. Heaven forbid you refuse one of there referrals. Saw a different Physician Assistant at my last appointment that was a one month follow up. I told this PA that a medication they gave me made me feel out of control and awkward. She said I was to take it before bed. I didn't have the fight in me to say, "The RX was written BID PRN for anxiety". I got the same response about medications that could be prescribed from this PA that I got from Lisa. A follow up should be with the person that originally saw me (at least that is my personal honest opinion). Just baffled, frustrated and confused. read more
