Mark Feuerstein; Ben Shenkman

There's a new doctor in the house: Ben Shenkman has joined Royal Pains as HankMed's newest hire, TVGuide.com has learned exclusively.

When the USA medical drama wrapped its third season in February, Hank (Mark Feuerstein) quit the family business after he and Evan (Paulo Costanzo) disagreed over a possible expansion. Shenkman, who  is set to appear in four episodes, will play HankMed's new employee, Dr. Jeremiah Sacani. Although he has a top-notch resume and a brilliant mind for science, Jeremiah has a serious lack of the social skills required for concierge medicine. Does this mean Evan might come crawling back to Hank?

It's also unclear what Dr. Sacani's hire means for Hamptons Heritage M.D. Paul Van Dyke (Kyle Howard), who Evan approached in the Season 3 finale after Hank's departure.

Shenkman recurred on Drop Dead Diva last summer and is also known for his roles on Law & Order, Grey's Anatomy, Damages and USA's Burn Notice.

Royal Pains will return for Season 4 this summer on USA.
