Mold Toxicity

Does your body seem to be fighting against you with seemingly unconnected symptoms? Uncovering mold toxicity means not only an explanation but with a Sanctuary detoxifcation protocol, this answer can also lead to feeling alive again with joy rather than suffering. Many have overcome before you. Join them. Learn more.

LYME and Target Borne Infections

Sometimes we discover Lyme is underlying a patient’s chronic illness…. With therapy… We see fatigue resolve. We see pains fade. We see vibrancy recover as the inflammation is quelled and the symptoms abate. As the infection and its toxins fade from the immediate picture, the body can be encouraged to function normally again. Learn more.


Many seek out our help for autoimmune conditions… Healthier, more abundant lives can then grow out of the fertile ground when (autoimmune) triggers are removed and nutrients energize the body. Patients can overcome not only the superficial symptoms, letting them return to normal life, but rest confident in knowing that the deeper unseen processes are no longer harming them. Learn more.


Where did my little Johnny go? Everything changed over a short period, maybe a night, maybe over a week, but your child morphed into another personality suddenly…. Your child’s health can be restored to a life of childhood joys unhindered by brain inflammation and unpredictable behaviors. The personality you knew can come back to life. Learn more.


Many come to us with bodies that just don’t want to get up and go…. With our care… They get more done at home or at work. They have more energy to have fun. Patients often express “so this is what it feels like to feel normal” or “I didn’t know how sick I really was until I felt better”. Learn more.

Autism and ADHD

As a parent, you know something changed about your child, something that you may not be able to pinpoint exactly, but you just know is there… By working to remove the triggers for brain inflammation and augmenting the body’s ability to heal, new changes emerge…. Your child can see a better future ahead interacting, learning, and playing. Learn more.

Long Hauler COVID

Reaching out for help with suspected or confirmed Long Hauler COVID or Post Acute COVID Syndrome? The acute illness wrecked havoc with our society and caused many severe illnesses for 1 to 3 week episodes. Then the prolonged illnesses many are experiencing are tormenting lives for months.  Learn more.

Mast Cell Activation Syndrome

Mast cells are immune cells which release histamine and dozens other chemical messengers in response to some trigger. The histamine and other chemicals serve a purpose under normal conditions, but when they build up in excess, they can cause hives, allergies, food intolerances, migraines, GI symptoms, and many other surprising symptoms. Learn more.

Thyroid Disorder

One might find it hard to imagine how a little gland sitting in their neck could cause so many problems when it fizzles, yet anyone with hypothyroid (low functioning) can attest to the multitude of symptoms it creates.  The thyroid produces thyroid hormone which controls our metabolic rate like a gas pedal.  Learn more.

Choosing the Right Supplement

Honestly, no one can know everything, even if they practice medicine for decades. Beyond that, even if you memorized all the current supplements, tomorrow a slew of new discoveries, products,…


Feeling the Burn After a UTI

Three little letters drive many women crazy.  U, T, and I combine into Urinary Tract Infection in millions of women yearly, causing significant discomfort and inconvenience.  For some, it is a short-lived condition that resolves with either natural remedies or antibiotics.  For others, the bladder pain can persist for days or weeks after the actual…

Proverbs 15:30

Proverbs 15:30 ESV The light of the eyes rejoices the heart, and good news refreshes the bones. []   Sickness of the body is a universal human experience. We all can remember a snotty nose or a headache or a stubbed toe. Too many of us know all about serious injuries, chronic illness, even the…


Mold and Multiple Chemical Sensitivities

For those not aware of our Mold Symptom Therapy Guide website, let this “Rewriting Mold” series serve as a reminder of both what we offer our patients and what we offer the general public in terms of understanding mold toxicity illness.  Over the coming weeks, I will be reviewing and reposting sections of our Mold…


Dad’s Gut Bacteria and Your Pregnancy

Some days, with all the research headlines, it can feel like we are controlled by the gut bacteria in our colons.  News headlines keep talking about dysbiosis and the effects of antibiotics on gut health.  Now we have one more twist that even surprised me a little.  I did not see this headline coming, the…


We knew something was wrong because our son wouldn’t engage in communication, he lost his desire to talk and he didn’t use eye contact – he was becoming isolated in his own world. But when we heard our son had autism, we were shocked. It doesn’t run in our families, we don’t use drugs or…
