Theresa Sullivan retires as Samaritan Healthcare chief executive officer

MOSES LAKE — Theresa Sullivan said what really interested her in the job at Samaritan Healthcare, back in 2014, was the potential for growth. Then-Chief Executive Officer Tom Thompson was recruiting an administrator. “What really attracted me was what he described in the need for services here,” Sullivan said. “I had been in a rapidly growing organization where we grew a lot of services, and I was excited about that possibility.” Sullivan took chief operating officer job and was promoted to the CEO job in 2015. After 11 years in that job, she’s retiring next week.
