"A Lifelong Friend and Truly Exceptional Physician I’ve known Dr. Ozzie Grenardo since the third grade, and I can say without hesitation that he is one of the most selfless, compassionate, and loyal people I’ve ever met. Over the decades, our friendship has grown into something truly special — he is the Godfather to two of my children and the confirmation sponsor to the third (who proudly considers him her Godfather as well). To our family, he is not just a friend; he’s family. My parents even refer to him as their “second son.” Ozzie has always been extraordinarily gracious to those around him. No matter how busy his life or career becomes, he consistently makes time for the people who need him. Whether it’s dropping everything to help in a moment of need or making the effort to keep lifelong friendships thriving, he does it all with humility and warmth. He’s the kind of person who quietly holds entire communities of people together — and somehow makes it look effortless. As a father, he has poured his heart into raising his daughter with the same integrity, love, and dedication that he brings to every other aspect of his life. And now, as he embarks on a new chapter — launching his own concierge medical practice through OGHealth.org — I can’t think of a more fitting evolution for someone who has always prioritized personal connection and individualized care. Ozzie doesn’t just treat symptoms — he cares for the whole person. If you are looking for a doctor who listens, who genuinely knows and remembers you, and who will walk alongside you through life’s ups and downs, there’s no one better. I love the guy — and once you meet him, I think you will too."

"I've had the privilege of knowing Dr. Ozzie Grenardo before his medical school days, and over the years, I've consistently turned to him for medical advice. From routine concerns like my annual sinus infections to more profound emotional challenges experienced with my children during their growing adolescent years, Ozzie has always been a compassionate and attentive listener. He takes the time to ask thoughtful questions, ensuring he fully understands the situation before offering guidance. His responses are prompt, and he never makes me feel rushed or burdensome—even when I might be testing his patience. What truly sets Ozzie apart is his unwavering zest and compassion for medicine, which have only deepened over time. I'm thrilled to see him channeling this passion into the launch of OG Health, a concierge family medicine practice. This new venture allows him to offer personalized, whole-person care, building deeper relationships with a limited number of patients. It's a testament to his commitment to providing individualized care that addresses both modern medical approaches and alternative methods when appropriate. My family and I have benefited from Ozzie's expertise and friendship for years, and we look forward to continuing this relationship for many more to come. If you're seeking a physician who combines clinical excellence with genuine compassion, Dr. Ozzie Grenardo is unparalleled."
