Katie-Jo’s Personal Health Journey

In my first 6 months as a Functional Medicine Nurse Practitioner I began to have severe pain in my feet until I could no longer stand or walk. I had to use a cane and wheelchair and was in extreme pain and fatigue. I was initially diagnosed with plantar fasciitis but was not recovering as expected. I went to a rheumatologist and was diagnosed with an autoimmune rheumatic arthritis called Peripheral Ankylosing Spondylitis, which showed up in my body as tendonitis in my feet, right knee, left hip, and left shoulder.

Then I witnessed a divine miracle in my life. Through prayer to God and the tools of Functional Medicine, the inflammation in my tendons substantially decreased. I used lab work, microbiome testing, herbs, protomorphogens, acupuncture, InfraRed sauna, physical therapy, chiropractic, alphabiotics, cryotherapy, and homeopathy to recover. I felt like I had been initiated into being a Functional Medicine Nurse practitioner through fire. I am a better practitioner for having this experience. My goal is to offer thorough, comprehensive and person-centered care with more kindness, more compassion, and more love.

“Spirit of Compassion has always said to me throughout the years of
helping so many people heal that knowing the true cause of why you’re
sick is half the battle. Knowing what to do, what to take, and how to
apply those tools is the other half the battle won.”

Patient testimonial

We have been patients of Dr. Manzanero for many, many years because he is a doctor with vast knowledge in many areas. He is a master in piecing medical information together and spending time discovering the root of internal imbalances or ailments.

Doctor Manzanero is thorough and follows up to make sure whatever he prescribes is working for the patient.

It took us many years to find a personal doctor, had given up on doctors who’s first concern is running a “business”.

We feel that Dr. Manzanero always finds the right balance so his patients can continue to living their lives with vitality.
