It’s draining our wages and savings, and impeding our economic freedom and well-being,” said Dr. Mass. “Women are more likely to have to coordinate medical appointments for their children, their parents, and themselves. I’ve been working on exposing the hidden cost of care and the barriers to access, and I’m honored to be the first physician visiting fellow to add what I’ve learned and to learn from this group of brilliant women.”
