Meet Our Staff


Dr. Lewis attended the University of Washington School of Medicine in Seattle, Washington and completed his pediatric residency training at Primary Children’s Medical Center in Salt Lake City, Utah. He was board certified in Pediatrics in 1993 and completed re-certification in 2000 and 2007.  Before founding Sancta Familia Center for Integrative Medicine, LLC he practiced general pediatrics for ten years in Salt Lake City, Utah and Billings, Montana, and served for seven years as Medical Director of the Pfeiffer Treatment Center in Warrenville, Illinois, where he treated children and adults with learning, mood, and behavioral problems with targeted nutrient therapy.

His medical career was directed down a different path when his child was diagnosed with autism at age two. Without a functional framework in traditional medicine for treatment of his child’s autism and associated medical problems, Dr. Lewis began to explore integrative, holistic and functional medicine therapies. Dietary intervention, targeted nutrient supplementation, and approaching treatment with a more integrative/functional framework proved to be effective in helping his child, as well as many of his patients. In response to seeing such profound effects with these treatments, Dr. Lewis continued to explore other integrative medicine modalities and was certified by the American Board of Integrative Holistic Medicine in 2002 and re-certified in 2010.

Dr. Lewis became Medical Director of the Pfeiffer Treatment Center in 2003. In this role he was able to concentrate on the treatment of children and adults with learning, mood, and behavioral problems, such as ASD – autism spectrum disorder, ADHD, bipolar disease, mood disorders, and behavior disorder. Additionally, he participated in research resulting in two publications1,2 on oxidative stress/damage in children with autism and one publication3 regarding a clinical diagnosis commonly referred to as pyrrole disorder. The more integrative approach to the evaluation and management of learning, behavior, and mood problems he developed at the Pfeiffer Treatment Center facilitated a more predictable, effective, and reproducible approach to the treatment of patients with these medical conditions. He has spoken nationally and internationally regarding the targeted nutrient management of the learning, mood, and behavioral problems listed above and was invited to author an article for the Autism Society of America member publication Advocate4.

The Sancta Familia Center for Integrative Medicine, LLC (fka Integrative Pediatrics of Ohio, LLC) was founded in 2010.  In the first year, Dr. Lewis started to see more patients with PANS/PANDAS and was interviewed by Tracy Townsend from Channel 10 News in Columbus, Ohio about PANDAS in November 2011 and her report aired that month.   Subsequently, Dr. Lewis has been recognized as a leading physician by and is devoted to bring hope and healing to patients and their families affected by PANS/PANDAS.  Naturally, this lead him to begin the life-long process of learning about and treating persons with Lyme Disease and related illnesses.   Attending his first ILADS<> conference in April 2014, Dr. Lewis has found the opportunity to find and treat the underlying causes of chronic illness in even more patients.

Nicole Snyder, CNP is a Board Certified Family Nurse Practitioner. Originally from Massachusetts, she graduated from the University of Massachusetts with a degree in Communication Disorders.  While there, she developed a program to be used in homeless shelters and soup kitchens for the identification and treatment of dysphagia (swallowing problems) among the homeless and marginalized.

Desiring to continue serving the poor, she lived for a time in Rome, Italy serving with the Missionaries of Charity. Her main responsibilities were caring for the very sick and dying homeless women. From that experience, she was inspired to pursue a career in nursing to better equip herself for service and to help bring God’s healing to the sick and suffering.

She studied nursing at the Ohio State University, and graduated in 2010 as a Family Nurse Practitioner and is board certified through the American Academy of Advanced Practice Nurses. She also is certified as a Fertility Care practitioner with Fertility Care Centers of America and has treated patients with a range of fertility and health issues.

In addition to providing general ambulatory and home health care, Nicole has worked at the Ohio State University Medical Center and Ohio State Interventional Pain Center treating patients with brain and spinal cord injuries as well as chronic pain.

Nick has always had an extreme compassion to help others, especially the sick & dying.  Nick, during his years of graduate school, started to really focus on allopathy and wellness and how it was linked to keeping people out of the hospital.  Nick’s focus is to treat the patient as a whole and not just the symptom.  Nick will use holistic integrative treatment options to care for Autism, ADHD, IASO, learning and behavioral differences, immune support issues and basic nutritional deficiency.

Nick has been married to his wife Kelsey for 5 years.  They have two children together, Parker and Palmer.  When Nick has spare time, he enjoys golfing, hiking, and watching sports. GO Browns!

Anita Cochran

Anita attended the Mt. Carmel School of Nursing program in Columbus, Ohio.  Her nursing career of over 25 years has been directed by a call to the service of others. She began by serving the elderly and medically fragile then to those facing the end of life and now to the care of children and families faced with unique challenges and special needs.

Before joining the practice in 2014, she was a patient care coordinator for Heartland Hospice. She lead her home-based team to care for patients in their homes at the end of life. Through this journey in hospice, her compassionate heart grew to care for not only the patient but the patient’s family. Using a holistic approach of caring for the physical, social and spiritual needs of the patient, gave her a great foundation for the care provided at Sancta Familia Center for Integrative Medicine.

Anita was drawn to the practice after meeting Kristin and Dr. Lewis and seeing the hope and healing offered to the families by Dr. Lewis and the staff. She feels blessed to be a part of this collaborative and supportive team.

At Sancta Familia Center, Anita uses her experience of being at the bedside of patients  and management to provide patients and their families with hope and direction through their current challenges.

Rachel Bulderbergs

Rachel is a  native of Hathaway, Louisiana but has spent most of her life in Central Ohio.  She is happily married to her husband Erike, whom she met in the U.S.A.F while serving their country together.  She is the mother of three amazing sons and one grandchild.
Rachel’s passion for functional medicine and the desire to learn how to use food as a method for healing began while journeying alongside her ailing father who courageously battled lung cancer.  Through this challenging experience, she began to question if there was more than allopathic medicine for cancer treatment as well as other diseases.  Following her father’s death, Rachel joined a local Wellness Health Forum and began learning how to treat illness through nutrition.
A few years later Rachel was once again invited to journey alongside a close friend who was diagnosed with non-hodgkins lymphoma.  This time however, she witnessed a very different approach to cancer treatment — synergistically using both chemotherapy and an alternative cancer treatment known as the Gerson Protocol.  This included juicing, an organic vegan diet and nutritional supplements.  Rachel was blessed with a favorable outcome this time and this in part led her to join the amazing SFC team!
When Rachel is not wholeheartedly serving patient families at SFC, you will find her camping, hiking or simply traveling with her husband and enjoying life as empty nesters.  Additionally, Rachel spends a fare amount of time serving her local church where she and her husband regularly worship.
Rachel is excited to be a part of SFC’s team, assisting patients in achieving optimal wellness — mind, body and spirit through integrative and functional medicine.
