Who Is Kathryn Hayward? All You Need to Know About Hilaria Baldwin’s Mother

Kathryn Hayward is an American physician, author, and health educator whose career began long before her daughter, Hilaria Baldwin, became a public figure. Many readers discover her through the Baldwin family, but Kathryn spent years caring for patients at Massachusetts General Hospital and teaching at Harvard Medical School.

Her career later expanded into integrative health, an approach that considers medical care alongside nutrition, movement, and other aspects of daily life. She created Odyssey Journey and helped develop International Integrators and Living Whole Online, bringing her experience into books, retreats, and educational programs.

From her Massachusetts background to her move to Mallorca, Kathryn’s story follows a professional journey that connects medicine, teaching, and family life.

Quick Info About Kathryn Hayward

Her Early Life in Massachusetts

Kathryn Hayward grew up in Massachusetts, the state where she would also study medicine and establish her clinical career. Her background places her firmly within the American side of the family story, despite the close connection she later developed with Spain.

Massachusetts remained central to her life for many years. Boston provided the setting for her medical education and professional work, while her children grew up in the area.

Her later move to Mallorca sometimes causes confusion among readers searching for Hilaria Baldwin’s parents. Kathryn’s connection to Spain came through her adult life and family interests; she built her early career in the United States.

Kathryn Hayward’s Medical Education

Kathryn graduated from Boston University School of Medicine in 1986. Her medical training also included an internal medicine residency at Carney Hospital.

Internal medicine focuses on adult health. Physicians in this specialty diagnose illnesses, manage ongoing conditions, and help patients understand their treatment options. Primary care internists often see the same patients over time, giving them a broader view of their medical needs.

That training formed the foundation of Kathryn’s working life. Before she began developing wellness programs, she had completed medical school and entered a conventional clinical specialty. Her later educational work grew from that experience.

Her Career at Massachusetts General Hospital and Harvard

Kathryn Hayward worked as a primary care internist at Massachusetts General Hospital and served as an assistant professor of medicine at Harvard Medical School.

These positions connected two parts of her career: treating patients and teaching medicine. Her professional biography describes approximately 20 years of service within those institutions.

The distinction between those roles matters. She practiced medicine at the hospital and held an academic appointment at Harvard Medical School. Together, they gave her a clinical and teaching background before she expanded her work into other forms of health education.

Her later projects continued that educational focus, although they reached audiences beyond medical students and hospital patients.

How Her Patients Changed Her Approach

Kathryn has credited her patients with encouraging her interest in integrative health. While working in primary care, she learned that some patients used practices that had received little attention during her medical training.

Their experiences prompted her to explore a wider range of questions about health and self-care. She became interested in how medical treatment could sit alongside food choices, physical activity, and mind–body practices.

The approach she calls Integrative Whole Health brings those subjects together. It also includes creativity and personal connections within its educational framework.

This does not mean that every activity within a wellness program serves as a medical treatment. Rather, Kathryn’s programs discuss several aspects of daily life alongside conventional medical education.

Starting Odyssey Journey and Writing Her Book

In 2004, Kathryn Hayward founded Odyssey Journey: A Collaborative Approach to Wellness, a private integrative health practice.

Through Odyssey, she developed work around self-care, personal challenges, and relationships. The program explores how people understand themselves and respond to patterns in their family lives.

She published Odyssey Family Systems Companion Guide in 2013. The book brought her family-systems approach into a format readers could use outside an appointment or group session.

Available in English and Spanish, the guide also reflects the two languages connected to her professional life across the United States and Spain.

Odyssey became one part of a larger body of work. Kathryn subsequently helped create collaborative programs that brought together professionals with different areas of experience.

Building International Integrators and Living Whole Online

Kathryn and a group of colleagues created International Integrators in 2013. Its mission centers on promoting Integrative Whole Health through education and collaboration.

The organization developed Living Whole immersion retreats, with gatherings in locations including California, Spain, and western Massachusetts. These events brought participants and facilitators together to explore different aspects of well-being.

The coronavirus pandemic interrupted the in-person gatherings. During that period, Living Whole Online developed as another way to connect participants and educators.

Its digital format offers courses, conversations, and educational sessions. Subjects include food, movement, writing, music, photography, and family connections.

The platform gives Kathryn and her colleagues a way to share their work with people who cannot attend a retreat. It also allows participants to explore individual subjects rather than joining an entire residential program.

Teaching Medical Students Beyond Harvard

Kathryn’s teaching work also extended into programs focused specifically on integrative medicine.

From 2011 to 2013, she served on the core faculty of the Leadership and Education Program for Students in Integrative Medicine, commonly called LEAPS into IM. She became its program director during her final year.

She later joined the core faculty for the Humanistic Elective in Activism and Reflective Transformation and Integrative Medicine, known as HEART-IM, for its 2014 and 2015 programs.

Both programs received support from the American Medical Student Association. These roles formed a bridge between her earlier academic career and her broader interest in health education.

They also show that her move away from hospital practice did not end her involvement in teaching future medical professionals.

Her Husband, David L. Thomas Jr.

Kathryn Hayward is married to David L. Thomas Jr., an attorney who also participates in their wellness work.

David studied Spanish literature at Haverford College before earning a law degree from Georgetown University. His interest in Spain therefore predates the couple’s move to Mallorca.

He later earned a certificate in plant-based nutrition through the T. Colin Campbell Center for Nutrition Studies. Within Living Whole programs, his contributions have included helping participants explore whole-food plant-based eating.

Their collaboration combines different professional backgrounds. Kathryn contributes her medical and educational experience, while David brings his background in law, language, and nutrition education.

The couple’s shared projects became part of their life in Spain, alongside Kathryn’s continuing work with an international group of colleagues.

Her Children and Connection to the Baldwin Family

Kathryn and David have two children: Hilaria Baldwin and Jeremy Hayward-Thomas.

Hilaria was born Hillary Lynn Hayward-Thomas in Boston. She later became a yoga instructor, author, and media personality, and married actor Alec Baldwin in 2012.

Through Hilaria, Kathryn is the grandmother of Carmen, Rafael, Leonardo, Romeo, Eduardo, María Lucía, and Ilaria.

Jeremy has received considerably less media attention than his sister. His name appears mainly in accounts of the family’s background and connections to Spain.

Although both Kathryn and Hilaria have worked in fields associated with well-being, their careers have followed different paths. Kathryn trained as a physician and worked in clinical medicine; Hilaria developed her public career through yoga, books, and media.

Keeping those roles separate gives a clearer understanding of Kathryn’s own professional identity.

Moving to Mallorca and Life in Spain

Kathryn Hayward and David moved to Mallorca in 2011, beginning a new chapter after years in Massachusetts.

The move changed the setting of her work without ending it. She continued developing educational projects, collaborating with other facilitators, and sharing ideas through writing and online conversations.

The family’s Spanish connection attracted wider attention in 2020 during public discussion of Hilaria’s accent and descriptions of her upbringing. Hilaria clarified that she was born in Boston and said she had spent parts of her childhood in both the United States and Spain.

For Kathryn, the timeline is straightforward: she grew up in Massachusetts, pursued her medical career there, and relocated to Mallorca as an adult.

Her professional activities in Spain have remained connected with colleagues and participants elsewhere, particularly through the online format of Living Whole.
