Dr. Hartz has been a lifesaver on my journey through mold illness, MCAS, and post-COVID complications. From the very beginning, her calm presence, deep compassion, and genuine care made me feel seen and supported in a way no doctor ever have. She combines exceptional knowledge with true intuition — always listening closely and tailoring care to the whole person, not just the symptoms. Her approach is thorough, thoughtful, and deeply human. Thanks to Dr. Hartz, I finally found a path forward — and more importantly, hope. I’m so grateful for her guidance, wisdom, and unwavering belief in healing.

Wow - it is going to be hard to put into words how grateful I am to be partnering with Dr. Cara. She is extremely passionate about her work. I was in very bad shape when I came to her. She spent a lot of time listening to my symptoms before creating a treatment plan. Prior to meeting Dr. Cara, I had been seeking answers (and suffering in the process) for over 10 years seeing every specialist and doing every test/scan/etc. It took her only a few months to discover my autoimmune disorder while also managing my mold detox. Dr. Cara has a very high level of emotional intelligence which shows through her empathy and communication style. I would recommend her to any family member or friend! THANK YOU DR. CARA AND TEAM!

Dr Cara Hartz has been a game changer for me and my health. I’ve been struggling for three years with chronic sinusitis and then developed all sorts of issues post Covid. I’d seen multiple doctors with no real answers. Within two months of working with Dr Hartz I’m feeling better than I have in the past few years, especially post Covid. My first appt she was prepared, had answers and potential solutions, and she was right in her predictions. I can’t recommend her enough! I’m so SO thankful for her.
