Dr. Mitchell first realized his strong passion for helping people through the wellness field while working at a drugstore in high school. That experience inspired him to earn his graduate degree in pharmacy and help people for more than 24 years. While practicing as a compounding and consultant pharmacist, Dr. Mitchell learned that many of the drugs dispensed for treatment were ultimately harming patients by suppressing their symptoms while allowing the underlying cause of illness to remain untreated. With this epiphany, Dr. Mitchell decided to pursue medical school and provide patients with the best of both naturopathic and conventional medicine. He completed his medical degree from the Southwest College of Naturopathic Medicine.

Dr. Mitchell’s first experience in using natural, restorative healing came before he even entered medical school, when he helped both his wife Ann and a family member with debilitating illnesses. At 20 months old, the family member was diagnosed with autism and was told that there was nothing doctors could do to reverse the disorder. His love for these members of his family kept him from accepting these answers and urged him forward to find alternatives, which included DAN! (Defeat Autism Now) training education.

While in school to earn his NMD, Dr. Mitchell trained under leaders in environmental medicine and autism, including Walter Crinnion, ND, Jessica Tran, ND, William Rea, MD, and Elizabeth Mumper, MD. Through that work, Dr. Mitchell developed his own treatment protocols and was able to further reverse the autism disorder and allow his family member to recover, develop, and thrive as a neuro-typical child.

Armed with those experiences, his time as a pharmacist, and with a medical degree in hand, Dr. Mitchell opened Lifestream Wellness to focus on endocrine (hormone), immune, and neurological concerns — the prime areas involved with environmental toxicity and commonly found in chronic disease states. Dr. Mitchell also specializes in bio-identical hormone replacement therapy (BHRT), chronic inflammatory disease, chronic infectious disease, and autoimmune disorders. In his office, he has a hyperbaric oxygen chamber, and he has even designed a unique cardiovascular plaque removal protocol that reduces deposits by alternating treatments that remove the cholesterol then chelates out the calcifications and heavy metals.

Dr. Mitchell is a compassionate listener who empowers and educates his patients, allowing them to fully understand their health and the healing process. Dr. Mitchell is a dedicated advocate and trusted advisor for patients in their journey to tackle their initial health concerns, the restoration process, and their quest for maintaining a life of health and wellness.

Dr. Mitchell has completed training for diagnosing and treating Lyme Disease and the co-infections that accompany it through the International Lyme and Associated Diseases Society (ILADS). Dr. Mitchell is a member of both ILADS and ACAM. His Lyme Literate education extends through ILADS, ACAM, and his naturopathic and pharmacy training.

Sydney Sharaf, NMD


“Went in last Wednesday with a 103 temp and Covid. Within two hours my temp was 100 and the Viral IV and breathing treatment proved to be a game changer. Went back for 3 separate treatments and it’s the only reason I am feeling as good as I am. The first day they sent us home with a pack of medicines as we waited including breathing treatments and then we got the compound pharmacy drugs day three. Thank you to the good Dr and staff that helped my wife and I out when we were very down and out. We will tell anyone who we come in contact with about their process as it works perfectly.”

His personal experience working through chronic joint pain, auto-immune disease, and Lyme Disease allows Dr. Despres to emphasize with his patients’ struggles. He too has seen countless conventional specialists who were unable to diagnose the causes of his symptoms nor could they offer true solutions.

His clinical skills include IV therapy, clinical nutrition, botanical medicine, detox/depuration therapies, physical medicine (spinal manipulation, massage, cupping, craniosacral therapy, visceral manipulation), peptide therapy, orthomolecular medicine, mind-body medicine, low level laser therapy, frequency specific micro-current, and hydrotherapy.

Kasandra Bujold, RN, FNP-S

Lab Director

“I can’t say enough about the care that I received from the Nizhoni team. I came in as I had just tested positive for Covid. They started me with a vitamin infusion and then provided me with a protocol for battling this stuff. After two weeks of adhering to their protocol, I am back at work and feeling pretty darn good. Not only did they give me stuff that helped heal me, but they did it with kindness and grace that truly let me know that they cared about me as a person and not just a patient. So, thank you Tanya and Cassie from the bottom of my heart.”
