Like the rings of a tree, care here deepens over time: layer by layer, year by year. It reflects your evolving needs, your values, and your goals for the life you want to lead.
While we treat illness, prevent disease, and aim to alleviate suffering, we also support what is strong and nourish what needs tending.
Whether you’re seeking clarity, navigating complexity, or simply investing in your long-term health, this is the place for thoughtful partnership for your health.
I’ve had an excellent experience with Dr. Julia Lowenthal and Lutanen Health. Dr. L is thoughtful, thorough, and highly responsive. She takes the time to understand the full picture, explains things clearly, and approaches care collaboratively and practically. I’ve especially appreciated the careful follow-up and the sense that my questions are taken seriously. I highly recommend Dr. Lowenthal and the Lutanen Health team.

Dr. Luthar and his entire team are amazing. Lutanen Health is a fantastic concierge practice. Every individual on Dr. Luthar’s team is a consummate professional and deeply cares about my overall health and well-being. I really like that the first and right answer is not just medication, but also providing a wide range of thoughtfully-crafted holistic options. If you’re looking for highly personalized, thoughtful, responsive primary care, I can’t recommend Lutanen Health more highly.

Without a doubt, my experience with Dr. Luthar has been the best healthcare experience I’ve ever had. Pinpointing his most meaningful strength is a challenge because the patient care, depth of knowledge, attentive listening, meticulous follow-up, and commitment to educating patients are all beyond exceptional. Dr. Luthar has a unique ability to make you feel as if you are his sole focus, providing a level of personal attention that starkly contrasts with any previous medical experiences I’ve had. For anyone seeking a true health partner, one who is dedicated to not only understanding and listening but also ensuring you’re thoroughly educated about your health, I cannot recommend Dr. Luthar highly enough.

Dr. Luthar is simply the best. He takes so much care, bringing his full attention and experience to bear on caring for patients. He listens deeply and takes his time. He clearly devotes himself to knowing the latest medical research and breakthroughs but complements traditional western medicine interventions with appropriate, evidence-based alternative therapies and interventions. He is a holistic and kind physician.

I highly recommend Dr. Luthar to anyone seeking a compassionate, skilled, and detailed physician. He demonstrates great patience, taking the time to answer questions thoroughly and empowering his patients to make informed choices about their health and wellness. Dr. Luthar instills a sense of trust and reassurance that is typically absent in the traditional care model and has been an invaluable asset in my health journey.

Dr. Lowenthal is an example of what an excellent doctor should be: thoughtful, thorough and deeply human. She will go the extra mile including personally reaching out to my other doctors to ensure that my care is fully coordinated and aligned. She has a beautiful calm and gentle manner which makes me feel heard, understood and safe. She blends the best of traditional medicine with a deep understanding of complementary therapies. I recommend her highly for anyone seeking geriatric care that is both medically excellent and genuinely caring.

Dr Luthar is an outstanding PCP. He is very knowledgeable about the frontier of medical research and diagnostics. And I have always felt extremely well advised and been provided with all the information I need to be part of my healthcare choices. He also has provided me with many useful ideas for healthy lifestyle adjustments that are practical and effective. And he is very kind and a pleasure to interact with.

Lutanen Health truly goes above and beyond, providing the most exceptional medical care I’ve ever experienced. Unlike any doctor I’ve seen before, Dr. Luthar genuinely listens, asks thoughtful questions, and takes the time to understand me as a whole person, not just a collection of symptoms. His depth of knowledge is remarkable, encompassing not only the latest medical research and treatments but also holistic and non-traditional approaches that complement conventional care. Since becoming his patient, my overall health and quality of life have improved tremendously.
