Margaret DiTulio


Margaret (“Peg”) DiTulio has been a Family Nurse Practitioner since 1995. After three years working in a small quintessential family practice with two longstanding family physicians, she established Rockingham Family Healthcare Collaborative Inc. to provide primary care in a holistic approach.

Peg holds Masters’ degrees in both science and business which has helped her to build her practice to 1500 patients as an independent Nurse Practitioner.

She has been a clinical nursing instructor of pediatrics at St. Anselm College in New Hampshire and provided clinical preceptorship to more than thirty nurse practitioner students from Boston College, Massachusetts General Hospital School of Health Sciences, Rivier University and the University of New Hampshire.

Prior to her role as a primary care provider, Peg spent seven years as Director of Community Services at the Visiting Nurse Association of Manchester and Southern New Hampshire. Additionally, she was the Director of Nursing Operations for Nutritional Management Inc.; a medically directed eating disorder program started by Harvard affiliated Dr. George Blackburn.

As a result of working in an area endemic for Lyme disease, Peg developed a subspecialty in the diagnosis and treatment of tick born infections. It was the interest in this area that led her to Dr. Shoemaker’s research into Chronic Inflammatory Response Syndrome (CIRS) in 2011. Consequently she has completed an intensive herbal apprenticeship in didactic, therapeutic and field work of herbalism. And she is pursing advanced studies in clinical herbalism at the Boston School of Herbal Studies.

Since that time she has identified and treated close to 100 patients with CIRS in her primary care practice. Currently, she consults outside her primary care practice under a separate entity, dedicated to environmentally influenced illnesses, Regenix Healing LLC: email - info@regenixhealing.com, telephone – (770) 734-3649.
