Functional medicine

Our personalized and holistic treatments get to the root cause of your health problems to promote true healing and well-being.

Sleep Apnea

Always tired? Struggling with night waking and snoring? Headaches when you wake up? You may be suffering from sleep apnea, a disorder that interrupts your sleep patterns by causing you to stop breathing several times at night. This results in a lack of oxygen to the brain and sleep disturbances, both of which can rob you of your productivity and leave you feeling fatigued during the day. Sleep apnea has also been connected to conditions including headaches, weight gain, behavioral conditions, and cardiovascular disease. Our team takes a biologic approach that can improve not only your quality of sleep but your quality of waking activities as well.

Naturopathic medicine

Naturopathic medicine is a holistic healthcare approach that combines natural therapies, traditional healing practices, and evidence-based science to promote wellness and prevent disease. Our Naturopathic Doctors address the underlying causes of your health issues with a strong emphasis on the body’s ability to heal itself.


At Rejuvenate Health, we incorporate acupuncture to your treatment plan to optimize your body’s potential and balance your life force — known in Traditional Chinese Medicine as chi or qi. We use it to treat pain, promote overall wellness, stress management, hormonal balance and more.


Homeopathy is a medical system we use that is grounded in the belief that the body can heal itself using natural substances from plants and minerals to stimulate the healing process. Homeopathy considers the whole person, looking at factors like personality, lifestyle, and genetics, as well as disease history to prescribe an ultimate treatment plan.


Experience a lifechanging natural, drug-free, non-invasive treatment to relieve allergies, addiction, anxiety, depression, and many other disorders. NAET reprograms your brain to tolerate allergens so that you can go back to enjoying previously off-limit meals, have more energy, and enjoy a better health physically, psychologically, and emotionally.


We incorporate B.A.H. to identify root cause dysfunctions of illness and personalizing a comprehensive treatment program. Conventional medicine tends to diagnose without paying attention to the cause of dysfunction, with B.A.H, we get to the root by considering the biochemical and physical, mental, emotional, and spiritual to help the body to restore its natural, inherited healing ability.
