Why Genesis Health

More Time to
Understand Your Health.

After training at Mount Sinai and working in conventional medicine, Dr. Ruth Johnson founded Genesis Health to give complex health concerns more time and attention.

Today, our practice brings internal, functional, and integrative medicine together through careful evaluation, selected testing, and ongoing care.
