Primary Care - Naturopathic Medicine

Meet Dr. Cara Hartz ND

A lifestyle, a philosophy and a way to practice medicine

Dr. Hartz, the creator of “ByHartz”, affirms that there are several paths to improve every person’s quality of life, and started the “Byhartz” project, as a way to share her knowledge and foundings with everyone. Make sure you follow us on social networks.

As a Primary Care - Naturopathic Physician, Dr. Hartz treats all family members, providing them with specific solutions according to their needs. This can apply to a very simple condition like a cold- flu or a more complex condition such as Lyme Disease. 

For many health issues there are not always easy and simple explanations, said Dr. Hartz: "You must be able to see the whole of the person to understand how the mind, spirit and every day habits are playing a role on the presented condition”. 

“I pay special attention to the mindset component, simply because the mind plays a fundamental role on the self energy healing process. Assessing the spirit of the person is a priority to decide which treatment plan is the correct one, whether it be 100% based on natural medicine or needs to include conventional medicine.


For Dr. Hartz, the priority is the whole person and their well-being.

I truly believe that if I had not found Dr. Cara, my chronic illness would still be misdiagnosed. I’ve been undergoing treatment for chronic Lyme disease, and under her direct care, I have received life-changing support. I have never felt so well cared for. And best of all, I’m getting better! Dr. Hartz passion for her work and her love for her patients is worn on her sleeve.I can’t imagine where I would be right now if it were not for her. Thank you Dr. Hartz!
