A special message from Dr. Dirkmaat herself:
"I keep up with research and integrate it into my care. I have worked with some of the top doctors in my industry and make recommendations that will be best for the child. My methods are safe and effective.
The blend of medicine I practice is an eclectic one. I use both Western and Eastern medicine to formulate the best outcome for the patients. My medicine serves a spectrum that accommodates both natural and conventional mindsets.
I provide safe, knowledgeable, quality care to the community. The care provided is non-judgmental and does not discriminate based on sexual preferences, orientation, gender, or vaccination status."

About Dr. Garcia
Dr. Amanda Daniella Garcia, ND
Hailing from the Lower East Side of Manhattan, Dr.Garcia has found herself in the beautiful state of Arizona after completed her residency in primary care in Vermont.
Dr. Garcia is a firm believer that there is always learning to be done, which is no surprise when you take a look at her career. She earned her Bachelors of Science in Electrical Engineering from the Johns Hopkins University, and went on to teach High School math in New Orleans, Louisiana. From there she returned home to NYC to continue tutoring and completed pre-requisites for medical school. In the midst of applying to medical school, she discovered Naturopathic Medicine and felt it aligned more fully with her values and principles. She went on to earn her Doctorate in Naturopathic Medicine from the Canadian College of Naturopathic Medicine in Toronto, Ontario.
As a third generation immigrant from Puerto Rico, and self proclaimed Nuyorican (Spanish speaking patients welcome if you can bare with my slang and practicing medical terminology), Dr.Garcia has great interest in providing primary care to people from all walks of life and making naturopathic care accessible. During her final year of schooling in Toronto, she interned at two community Healthcare centres whose purposes were to provide free naturopathic care to underserved populations which included those who were low-income earning, BIPOC, and apart of the LGBTQIA2+ community, and/or indigenous.
Out of all the modalities in naturopathic medicine, Dr.Garcia loves homeopathy, acupuncture, and botanical medicine. She is passionate about primary care, and is willing to put in the time and effort to work together with her patients. Teamwork makes the dream work!
If she isn’t in the clinic, you can find her thrifting, baking, dabbling in photography, or lost in a romantasy series.
Dr. Garcia is now welcoming new patients of all ages in our Queen Creek location.
