Get to Know Dr. Barry Witt

As an expert in reproductive medicine who has helped build countless local families, Dr. Witt looks forward to the holiday season each year, knowing he will receive cards and updates from many of the grateful parents he has worked with.

"It used to be pictures of babies, but now it’s pictures of 20-year olds who are going off to college," says Dr. Witt. "It’s obviously incredible to help bring a life into the world, but in the long-term, it’s about creating human beings who are going off to impact the world."

What inspired his career?

Dr. Witt feels that working in reproductive endocrinology is both personally and scientifically rewarding, and enjoys the fast-paced, ever-evolving nature of the field.

"Obstetrics has been around for millennia, but reproductive endocrinology is much newer and cutting-edge," he says. "I enjoy being a part of the dramatic improvements we have made over the years in terms of in vitro fertilization, genetic testing, and fertility preservation," he says.

On his future at Illume Fertility: 

"I am honored to join the talented team at Illume Fertility, and I look forward to continuing to serve both Westchester and Fairfield Counties with a high level of personalized, state-of-the-art care," says Dr. Witt.

His decision to join Illume Fertility was propelled by the practice's commitment to patient experience and advancing inclusive fertility and family-building care in the community.

"Illume is unique in that it pairs world-class fertility treatment with individualized emotional support and integrative programs such as nutrition, yoga and acupuncture," Dr. Witt says. "Becoming part of the team at Illume Fertility will allow me to help even more hopeful parents with a wider array of resources to support their personal journeys."

Dr. Witt will begin seeing patients at Illume Fertility in January 2024. He will be based primarily out of our Norwalk and Stamford, CT locations, and our Harrison, NY location.
