Resilience Specialist

Maria Trozzi

Maria Trozzi, M.Ed., is an O2X Resilience Specialist. She is an assistant professor of pediatrics at Boston University School of Medicine, Director of the nationally renowned Good Grief Program at Boston Medical Center, a consultant to the Child Development Unit at Children’s Hospital, and an author. Her credentials and expertise have established her as one of the foremost experts on child and family bereavement in the country. Most recently, at the request of the Pentagon, she has been hired as the special resilience consultant to the Naval Special Warfare Development Group.

She has provided consultation at Littleton, Colorado, at Ground Zero in the aftermath of 9/11 and in Grenada following Hurricane Ivan. Since 1991, she has lectured nationally to professional audiences in every major city with Dr. T. Berry Brazelton as a regular faculty member of the National Seminar Series.

For nearly 20 years, as Director of the Good Grief Program, her training for educators and health professionals focuses on promoting resilience in the face of loss via strategies that strengthen coping skills for families, institutions, and communities. Immediately following 9/11, Trozzi’s principal work expanded to care for the loved ones and their families of the victims of the two planes that had emanated from Boston.

Trozzi’s interest in bereavement expands to the grief families experience when a child is diagnosed with a disability, a grief that keeps on giving. Her research is focused on identifying grief touch points – predictable times in a disabled child’s development when parents’ grief is exacerbated. Trozzi’s model for professionals and parents has taken this grief ‘out of the closet’ for both affected families and clinicians that treat them.

She is a frequent contributor to both print and electronic media. She has appeared with Dr. Brazelton as co-host of his national television show “What Every Baby Knows” multiple times, as well as several national news programs including “Larry King Live”, Early Show, CNN, NBC, ande ABC.

Her first book, Talking With Children About Loss, was published by Putnam-Penguin and continues to be an essential reference for parents and professionals. She has also authored several chapters in pediatric and academic textbooks.

She is the parent of two adult daughters and lives in Boston and West Yarmouth. She maintains a private practice dedicated to issues of loss and provides consultation to families facing stressful life events.

Her philosophy is that nutrition and fitness should be for life, not a single event (or outfit). To do this, we need to follow scientifically-sound and sustainable practices, not the latest story or fad from the media. Maria uses her education in biochemistry, physiology, and nutrition, as well as personal experiences with competitive running, to develop nutrition and exercise plans that make sense and allow her ‘students’ to eat and train for life. She understands that this is an ever-changing field, and staying on top of the latest research is critical. She has published over 30 papers in scientific journals and several book chapters, but she is most comfortable when using her scientific background to write or speak about nutrition and fitness practices. In her free time, Maria loves to run, swim, hike, adventure travel, and read.

Janel explained, “I managed to trade my photo and marketing skills for a 200-hour yoga teacher training and began teaching a few classes at the studio where I practiced near my house.”

Her newfound love of yoga—and teaching it—quickly turned into ownership of Trinity Yoga Studio. Janel credits the leadership and work ethic instilled during her military training as a large part of how she formed her path from U.S. Air Force to business owner: “Once you enter into the ranks, there’s constantly a push for growth. Making rank and supervising others is just part of the natural progression of things—the nature of how the military operates instills confidence, a sense of purpose and direction.”

Eventually, Janel wanted to give back to other veterans like her, which led her to co-found the Veterans Alternative, a non-profit organization designed to serve Veterans experiencing trauma incurred while serving in the military by training the mind, body, and spirit to heal after returning home from military service.

As a B-52H pilot, Hunter led his crew in accomplishing a variety of missions. Missions including nuclear deterrence, close air support, air-to-ground, direct attack, and counter-drug. In 2015, Hunter volunteered to be an Instructor Pilot and was thus tasked with the crucial and vital role of instructing and producing the Air Force’s next generation of highly skilled and capable pilots. 

On Easter Sunday 2017, Hunter suffered a seizure caused by a previously undetected brain tumor which required immediate surgery to remove. Hunter was subsequently diagnosed with malignant brain cancer, thus cutting short his military aviation career. The diagnosis led Hunter to develop a deeper respect for resiliency and a new-found passion for teaching others how to implement the life-saving and life-enriching skills into their own lives: “I had received hundreds of hours of resiliency training from the Air Force for the purpose of instructing other Airmen. Even in passing along those resiliency skills to others, I had failed to internalize and apply those skills myself, but that all changed when I received my cancer diagnosis.” The skills and techniques he once used to teach undergraduate pilots now enables him to teach and instruct thousands in developing and building their own resilience. 

Hunter resides in Columbus, Ohio with his wife Crystal, son Nolan, and dog Riley. Despite being found medically unqualified to fly, his passion for aviation continues. He enjoys studying leadership, is a proud Ohioan, and a die-hard Ohio State Buckeye athletics fan, especially football and hockey.
