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 drink and we eat mostly organic. He was diagnosed with autism when he was 4. I didn’t for a minute think he was born with it, which is what our pediatrician told us. We had our son genetically tested and found out he had an MTHFR defect. Upon researching we found Dr. Potter to be an expert in this area. When we saw Dr. Potter and his staff they worked on finding the underlying problem instead of pushing some pill. His autism was treated as a symptom and not the underlying problem. Through a serious of labs, we found out that our son’s cells were very rancid after being contaminated. We suspected aluminum to be the cause and we were right. Dr. Potter put us on a program to fix the rancidity and remove the aluminum. It had been about 8 months now and our son is well on his path to a full recovery. He is no longer in his own world, he communicates, he uses eye contact, he laughs and cracks jokes. He is 6 now and he is still a little behind, but that is because we lost him for a couple of years. Our pediatrician would have never ordered the test Dr Potter did and would have only put our son on some drug he did not need. If you want to fix your underlying problem and get healthy again, your best bet is with Dr. Potter.

“For years, my child suffered from symptoms such as fatigue, joint pain, headaches, and frequent illnesses. After not getting satisfactory answers from my son’s medical practitioners, we decided to go to a functional medicine doctor in hope of discovering the root causes of his poor health. We decided on Dr. Potter at Sanctuary Functional Medicine after reading extensive reviews and researching all of the Institute of Functional Medicine certified providers in our area.

We are so thankful we found Dr. Potter; he has always listened closely to our concerns and patiently guided us through the testing process and treatment plan. He is incredibly knowledgeable, approachable, and responsive. A year after first being seen at Sanctuary, my son is in much better health with most of his symptoms either gone all together or greatly improved. During the same time period, nearly all of his abnormal lab work has also returned to normal. We are equipped with so much information about my son’s health and how to help him lead a healthy life moving forward. Dr. Potter and his staff have been very supportive and excellent resources during this journey.”

“I am still in the treatment phase, but it has been amazing so far! I have already recommended SFM to an acquaintance, and she is now a patient there. I wish I had found Dr. Potter and the SFM family before, but I know God’s timing is perfect. I have complete confidence in Dr. Potter and Hans and already feel better even though I am just getting started…knowing the root cause of my symptoms/suffering is such a huge relief!”

T Drew

In 2016 I was living in Clarksville,

Tennessee when I noticed I was becoming ill. I only noticed this after being sick and having kidney stones surgically removed from my body the previous month. My illness was so bad that I was having thyroid failure, inflammation, fatigue, vision loss, hearing

loss, brain fog, short term memory loss, rashes, constant allergic reactions, and chemical sensitivities’ had bleeding of the gums. My children started having trouble sleeping and complaining of the same symptoms. They were getting sick easier and they looked

as if they were also having inflammation. I was getting so sick and weak that I could barely maintain walking any sort of distance. I could barely walk.

In 2017 I noticed mold growing under my house after a big storm I could smell something that was literally making me sick. I asked my husband to look under the house for mold and as he did he found mold growing under the entire bottom half of our basement. I got the mold tested told the landlord and left all my belongings behind on a journey to heal my children and I. After I had moved back in with my father with my children I was still sick. I went to the hospital multiple time. Each time I visited the hospital because I couldn’t breath and

literally thought I was going to faint and die, they told me all my test were normal and that nothing was wrong with me. They told me maybe it was anxiety which was not true one bit. When I took the kids to the pediatrician they knew nothing about mold poisoning

or about detoxing. They looked at me like I was crazy and shrugged me off as an overprotective parent. Mold is toxic is what I kept telling the doctors and I had been living there for a year. Before I healed I had to use an epi pen about 5 times shot in my leg to make sure I didn’t die from anaphylactic shock. No doctors believed me that I was really sick. My own family didn’t believe me. My own husband didn’t believe me.

Visit to Sanctuary Functional Medicine

I had a DNA exam done. They told me that mold in fact was poisonous and to keep my children far away from it. I said “finally someone who knows what they are talking about”. From my blood samples and dna exam they explained that I had gasoline poisoning, plastic in my digestive system, and also was experiencing mold toxicity. I also had a positive Lyme disease test. I knew my children were experiencing all the same problems I was having as they were living in the same house as I was. I started a regime of continuous vitamins and activated

charcoal in the morning for all of us. I was given a nutritionist who explained that food is medicine and I should be gluten free, only eat organic, avoid dairy, avoid sugars, avoid processed foods, avoid gasoline plastics, alcohol anything that could potentially

poison my body they told me to keep toxins out of my environment. Aka No more gasoline aloud in the house. Aka no more microwaving food in plastic. my husband would always do that.

Solution preventative medicine and detoxing therefore preventing the occurrence+ of future disease or illness. I was told to get a full house water purifier because the water that comes out of our faucet if not purified and contains pharmaceuticals and toxins from old pipes. I was taught that roots heal, I was told to take Epsom salt baths daily until fully detoxed. Give the kid’s baths with a spoonful of baking soda to detox them. I also gave my children in their sippy cups activated charcoal every day to heal them and bind any poison that might be in their little bodies. I was told to invest in theives essential oils and that they help on a cellular level. I needed to take about 15 daily supplements from now on until I heal. I learned to keep my body acidic with lemon water and hydrate and sweat it out. No bacteria or virus can thrive in your body if it is acidic enough. I was also told that If I see a leaky roof or if I notice mold in a building that I am in then leave. Not everyone knows this information and some people just die thinking that they don’t have a choice. Also in the midst of all of this most importantly I had Dr. potter praying over me during every appointment.

Covid 19

2020

All my children are healed as am I. My children are detoxed. I still regularly give them preventative medicine aka vitamins and Epsom salt baths and essential oils. I also still give them activated charcoal if I have noticed them in a moldy environment that most people don’t pay attention to. I have strong enough energy to work three jobs and provide for my family all on my own. I work at a community where our veteran hero’s live and doctors who are now too old to take care of themselves and I work there to provide assistance. I am a server,

house keeper, and personal assistant to them. I continue to take my vitamins, always using essential oils, always staying away from things that might potentially be poisonous to me. I avoid harsh chemicals. I avoid touching gasoline while pumping my gas. I

eat only lean meat and high quality organic veggies and fruits. I say no to anything that is processed or fast food or that has preservatives.

I am grateful that Dr. Potter has walked with me on a long journey. When I first met with Dr. Potter a few years ago it would be an understatement to say that my overall health was not in a good place. I had seen many doctors through the years as I sought help to address my issues. Since I was not overweight and had healthy cholesterol numbers many doctors tried to tell me I was perfectly healthy. Along with other symptoms, I lived with chronic, and at times extreme, fatigue along with chronic joint pain. I embarked on a journey of healthy eating which led to improvements, but the crushing fatigue and joint pain were always present to some degree. Dr. Potter has patiently peeled back the layers of my multi-faceted problems and helped me work through them. My quality of life is immeasurably higher, I’m a better wife and mother because I don’t have daily joint pain and fatigue. As a business owner I’ve been able to be joyful and passionate in my work again. Everyone at Sanctuary Functional Medicine has treated me with compassion and respect from the first day I walked through their door. I am grateful to be one of their patients.

I lived most of my life with chronic respiratory infections that required multiple rounds of antibiotics and steroids. In 2017 Dr. Potter taught me about Glutathione, the master antioxidant. My levels were very low and I began supplementing the liposomal form along with high dose vitamin C and other supportive herbs. After just a short time, the change was nothing short of miraculous. I have faced many health challenges since that time, and we continue to work towards optimal health, but my immune system has remained strong through it all! I’m so thankful for Dr. Potter and his willingness to teach while he treats.

I am very thankful to have come so far in my healing journey. I was just thinking this morning that I no longer have that overwhelming feeling of fatigue when I first wake up. You, your knowledge, protocol, and staff have been and are such a blessing to me (and my family). To have a doctor and staff who pray over their patients and seek God’s wisdom is a blessing that I do not take lightly. Brings to mind the verse from Philippians – “I thank my God upon every remembrance of you.” I am still praying for you, your family, and staff. Even on those not so great days – I am encouraged that God has a plan and that He walks with us through these faith stretching times in which we live. Blessings

It had been about 8 months now and our son is well on his path to a full recovery. He is no longer in his own world, he communicates, he uses eye contact, he laughs and cracks jokes. He is 6 now and he is still a little behind, but that is because we lost him for a couple of years. Our pediatrician would have never ordered the test Dr Potter did and would have only put our son on some drug he did not need.
