Dr. Thomas Novak looks at his role as a doctor more as a vocation — a calling — than a job.Novak, a family practice physician at Mercy Family Medicine in West Branch, a clinic of Mercy Iowa City, has been caring for families for 30 years. He enjoys getting to know the whole family and understands that what happens to one person impacts everyone else in the family.And, on a bigger scale, “what happens to one person impacts the community,” he said.Given that some people lack access to the basic needs such as proper medical care, Novak said he feels that being in a position where he can provide those basics means that he should.“We all need to find something we can do to give back,” said Novak, 59, of Iowa City.That belief is what drove Novak to open a monthly foot clinic in the Iowa City Catholic Worker House this year.Each month, Novak and other volunteers offer free foot care services for those who are homeless or otherwise lack access to resources.
