Dr. Manna Semby, ND

Dr. Manna Semby, ND, feels privileged to have been guided to becoming a naturopathic doctor. In her previous life, she was a CPA and worked on Wall St for 12 years. During this time she was a faithful believer in conventional medicine. A series of unfortunate experiences with her children’s health and the lack of solutions, support and compassion from the pediatrician convinced her that she needed to look elsewhere for answers. Within a few short years, Dr. Semby discovered homeopathic, naturopathic and functional medicine. She switched gears from finance to medicine, taking 3 years to study homeopathy and then 2 years to complete science prerequisites to attend medical school. She graduated from Bastyr University in San Diego, CA, with a doctorate in Naturopathic medicine. Today, she is a passionate believer in the naturopathic therapeutic order which establishes the primacy of the foundations of health: individually optimized diet, exercise, thinking, living, working and relating. She thrives on meaningful dialog and relationships with patients, clinicians and staff at Solcere.

Dr. Semby relishes listening to and connecting with patients at the deepest level. When the patient and doctor are in deep sync, a beautiful triune entanglement in the relationship emerges which (borrowing from homeopathy research by Milgrom and Hankey) creates quantum coherence and is instrumental in devising the right combination of therapeutics that will bring the patient back into a state of homeodynamism (“ability to dynamically self-organize”). With each patient, Dr. Semby considers the latest empirical evidence before devising a treatment plan. Her interests include complex chronic illness such as mold and lyme, reversal of cognitive decline, cardiometabolic health, endocrine (hormone) issues, and integrative oncology. She is also passionate about providing care in group/community settings and working with corporate leaders and HR to devise optimal health plans for employees. She is trained in functional medicine and is RECODE 2.0 certified with Dr. Dale Bredesen protocol to reverse Alzheimer’s. She has been trained by Dr. Iris Bell, Dr. Joe Pizzorno, Dr. Kara Fitzgerald and Dr. Leigh Erin Connealy. She is currently being mentored by Dr. Neil Nathan and Dr. Paul Anderson.

Nadia Ramirez

Nadia Ramirez was born and raised next door in Carlsbad, California. She has her Bachelor of Science in Kinesiology from Sonoma State University. During undergraduate studies, Nadia developed her interest in fitness and physical health, and received her NASM Certification to train clients while carrying a full course load. After graduating, Nadia worked as a Physical Therapy trainer at a boutique physical therapy center while still continuing her education and exploring her many different interests in health care.

She was led to North County Natural Medicine due to her own personal experience and desire to understand how we can heal deeply rooted wounds through developing and nurturing our own body, mind and soul. She came across NCNM’s philosophy and it resonated deeply with her. Nadia loves learning and being part of a community that promotes such practices. Nadia spends her free time in nature and being active. She loves to climb, run and surf. Nadia is fascinated by each individual’s capabilities and the power our perception has to shape our experiences. She hopes to help others see and experience the beauty life has to offer.
