Dr. Martha Keith, ND
NATUROPATHIC DOCTOR
Hi, I’m Dr. Martha Keith and my journey into medicine actually began as a patient. In my early 30s, I was diagnosed with trigeminal neuralgia, a rare nerve disorder so painful it left me unable to function.
That experience drove me to ask big questions about why we get sick and what it truly takes to stay well. Along the way, I discovered that real healing comes from blending modern medical science with naturopathic principles—a combination that not only healed me but also changed my life and inspired my career.
While in medical school, I faced another challenge—my weight. I realized this has to be a solvable problem and immersed myself in the science of weight management, ultimately transforming my own health. That personal victory became the foundation of my practice because I’ve seen firsthand how addressing weight can unlock better health in every area of life.
In a classic hero's journey, overcoming my own struggles with weight ignited a passion for helping others achieve the same transformation. Now, I’m dedicated to sharing those solutions with the world and empowering others to reclaim their health.
Get To Know Us
The Faces (and Fur) Behind The Practice
Dr. Martha LLC started in Honolulu, Hawaii, as a small, family-owned practice with a big mission: to deliver personalized, results-driven healthcare that starts with weight management. When my husband’s career as a nurse practitioner brought us to Arizona, we brought the practice to Tempe where I now serve patients both locally and in Hawaii through telemedicine.
We’re still a small, family-run operation—just me, my passion for patient care, and my unique approach to medicine. There’s no staff to answer phones (unless we can train the cats!), no receptionist, no medical assistants, and no layers of bureaucracy. It’s just one-on-one care, tailored to you.
Whether you’re in Arizona or Hawaii, my focus is on delivering the results you deserve through a blend of modern science, naturopathic wisdom, and plenty of heart.
