A New York company that helps patients connect with doctors through an online service is opening a Scottsdale office and will hire more than 600 workers in the next three years.

ZocDoc is a free service for patients that also lets them book appointments online. Gov. Jan Brewer and Scottsdale Mayor Jim Lane announced the office opening on Tuesday.

Brewer has made three other major jobs announcements in recent weeks, including a new General Motors information technology innovation center in Chandler that will have 1,000 high-tech employees.

All three are benefiting from incentives from the Arizona Commerce Authority.

The Commerce Authority also was involved in Tuesday’s announcement.

The company says it will hire nearly 70 people to staff the office by year’s end.
