Kathryn BarberMay 27, 2025 I have been a patient of Griffin Concierge medicine for a little over a year and have to say, it has changed my life. As a mature patient with a complex medical history and after a long search for compassionate, proactive care, Griffin has renewed my belief that high quality healthcare can be found. Everything you read on the website is 100% true - the experience is one of genuine caring for your wellness as if you are a family member and respectful, intelligent and informed interactions. My physician has been Dr. Timothy Nobles, however I believe that all of the physicians with the practice must meet a very stringent criteria and embody the Griffin philosophy of care. In early June Griffin is opening a second location in St. Petersburg. I wish them tremendous success which they surely deserve and will be a Griffin patient and cheerleader for life! Edna GonzálezMay 20, 2025 Griffin Concierge Medical sets the gold standard for personalized, proactive healthcare. Their entire team—from physicians to support staff—operates with a rare blend of warmth, professionalism, and clinical excellence. The care they provide is truly elevated, with thoughtful attention to each patient’s individual needs and a seamless coordination of services that makes navigating healthcare easier and more reassuring. We’ve had the pleasure of supporting many of the same patients, and the Griffin team always stands out for their responsiveness, compassion, and unwavering commitment to quality. They are a trusted partner in the community—and a true gift to the families they serve. Britt WilliamsJanuary 14, 2025 Excellent experience! I joined the practice in October 2024 and recently had my first annual physical with Dr. Owens. I could not be happier. My tendency is to be a pretty nervous patient. Dr. Owens and her team took the time to listen to my concerns and address them one by one. I haven’t had such dedicated personal attention before. When I left the office, I called my mom and said “this practice is so worth it”. Thank you Dr. Owens and team. Looking forward to taking my healthcare journey with you. lisa monahanJanuary 10, 2025 After recently moving to Tampa, I asked for a doctor recommendation from a trusted friend. This practice is amazing and i can’t speak highly enough about my doctor, Dr. Jenna Donosa. She is so incredibly dedicated to her profession and her patients. She actually makes me want to go to the doctor, which definitely has never happened to me before. Her staff is also incredible… Christal Is so kind and competent and always on top of helping you be healthier. I recommend this practice and wish I had found them sooner. Allison WilkinsDecember 9, 2024 The best decision we have ever made was to become patients of Dr. Deborah St. Clair. Her expertise in the medical field and knowledge of current best practice exceeds any physician we have ever known. She is kind, thoughtful and takes the time to listen to your concerns before weighing in. My husband and I became entirely fed up with the in/out cookie cutter approach to healthcare that we have experienced in the past, prior to joining Griffin Concierge Medical. Their entire team of providers is outstanding, thorough and best of all reachable! Becoming part of this practice has added to the quality of our lives and reduced our stress levels when occasional sickness arises. If you are tired of being a number in the healthcare system and not getting proper medical care- invest in a better quality of life with this outstanding practice. It is worth the investment and could add years to your life. CAROL GOULDOctober 5, 2024 My husband and I have been here a couple years, and what a wonderful experience! Dr. St. Clair saved my husbands life, literally, by giving the very best medical care possible in a very difficult situation. Griffin Concierge gives me peace of mind I have medical answers 24/7. One million stars! DetrickAugust 16, 2024 Switched here almost a year ago after dealing with an unorganized PCP. My old PCP office barely answered the phone. The wait time was 1-2 hours in the lobby to see the MD at my old PCP office. Griffin Concierge is different . Took a little time to get used to a concierge practice. They are extremely fast (literally) . I really like my patient advocate (Jen ) . Dr Griffin & Dr Nobles please keep her around lol. I like that I don’t have to set appointments just to ask questions. I have even had less ER visits under this practice. Someone always has an answer or calls back with one . Even the receptionist is friendly . Try these folks out . Nicole HackneyJuly 17, 2024 I have been a patient of Dr. Griffin’s for almost 15 years. The concierge aspect of medicine has been an investment at an early age and I highly recommend this to anyone ready to make an commitment in their long term health. Griffin concierge has been by my side as a young adult and I value the professional and highly skilled team Dr. Griffin has developed. Kate HendershottJune 30, 2024 Griffin Concierge Medical is truly a premier medical concierge practice. From a client’s very first appointment, I was impressed by their genuine care and professionalism. The team's attention to detail is evident in every aspect of their service, from thorough lab work to quick responsiveness. Their medical knowledge is top-notch, ensuring comprehensive and personalized care. Most importantly, they genuinely care about their clients' well-being, making every interaction meaningful and supportive. I highly recommend Griffin Concierge Medical for anyone seeking exceptional medical care with a personal touch.
