Dr. Josh Conzo DC, CFMP
This month, we are highlighting Dr. Joshua Conzo. He has been working in the functional medicine field since completing his Doctorate of Chiropractic in 2012. His love of functional medicine and nutrition began when dealing with his own family and personal autoimmune conditions and seeing where traditional medicine was missing the underlying cause. His focus areas include autoimmune disease, endocrinology, digestive health, pediatrics, functional neurology, and childhood neuro-developmental disorders. He completed advanced training as a Certified Functional Medicine Practitioner (CFMP) at the Functional Medicine University, further developing his knowledge and skills in diagnostic testing and healing based on treating the root cause of disease.
Dr. Josh has also completed training under the Kharrazian Institute – specialties included functional endocrinology, functional brain chemistry, and lab analysis. To continue his training, he has completed over 300 hours towards his American Clinical Board of Nutrition Diplomate (DACBN) and is board eligible and is currently enrolled and almost completed in the Chiropractic Internist Diplomate (DABCI). He has completed his hours and training for the Fellowship of Childhood Neurodevelopmental Disorders and is soon to take his exam.
Dr. Conzo has always had an interest in children and developmental delays which led him into Dr. Robert Melillo’s childhood developmental fellowship. After completing the fellowship testing, he will be Melillo Method trained, as well. Dr. Melillo is world renowned for work with autism and ADHD and has written many books explaining these disorders.
When he isn’t helping patients, he spends time with his beautiful wife and two little boys outdoors.

Mindy Williams
I was raised in Norco, CA, a small horse town. I value family, friends and support small businesses. I went to Southern California School of Massage June of 1996 and worked immediately at Glen Ivy Hot Springs Spa where I practiced Swedish/American, Deep Tissue, Prenatal and stone massage along with many body treatments. From there, I moved to a Chiropractic business to learn more about targeted areas. I am passionate about helping and healing. I am married with 2 young adults - both in college. My son is attending CSU and my daughter will be at DU to get her Masters. We relocated to Berthoud when I inherited my father’s house. I love the small town feel of the community! I enjoy helping others and above all making memories with my family. I thank God everyday for his grace.

Mrs. Kelly Wisniewski
A licensed Esthetician for 16 years, Kelly originally started off going to Cosmetology school. Once realizing that the skin care portion of Cosmetology was lacking, she returned a year later to become an Esthetician. Being classically trained at an Aveda based school, she was fortunate enough to have a teacher that was open to teaching all different modalities.
Kelly has worked in a salon/spa with 40+ employees that specialized in skin care, massage, nail care and hair care. Training under the owner of that spa taught her the importance of a diligent work ethic and listening to her clients’ goals and needs.
