    Jason is a true professional in terms of knowledge, dedication to medical practice and standards as well as care. My only issue is that he, like the majority of his fellow medical practitioners, are focused on your medical condition today: medical management versus the alternative of wellness care focused on anti-aging and preventing advanced aging or disease progression.

    Dr. Barrera is a wonderful primary care doctor. He is thoughtful, friendly, kind, and very, very easy to talk to.

    Dr. Barrera seemed very present. Asked great questions. Listened to information I reported, setting up immediate tests that led to relevant results.

    I've had Dr. Barrera for about 9 years as my PCP. He's caring, sincere and honest. He listens to my concerns and allows me to be myself without forcing me to take a medication I am not comfortable with. I like changing my diet to help with blood pressure and cholesterol issues. He is knowledgeable and he never makes me feel stupid, even though I am elderly. I'm not surprised that he received a promotion because he is dedicated to what he does.

    My mother has been a patient of Dr. Barrera's for quite some time now, many years. I'm her daughter. I'm her healthcare proxy. And my mom has Alzheimer's disease and a bunch of other comorbidities. And Dr. Barrera is honestly the best doctor I've ever, you know, been in communication with for her care. And being, you know, her family, he is just so respectful and listens to what we have to say. The best part is that he takes into consideration things that I suggest, which is, you know, remarkable that he would listen to, you know, patients and family so much. He's extremely patient with us and he's, always in communication with us either by patient gateway or calling himself.
