Donna came to Sellers Dorsey from Health Watch, which at that time, was the second largest Medical Alert/Personal Response Systems Company in the United States, serving 125,000 subscribers and employing 300 people. Ultimately Health Watch was bought by Royal Philips Electronics. At the time of the purchase, Donna was Chief Financial Officer, Treasurer, and Secretary and remained with the company through the transition, ensuring a smooth transfer of all accounting functions, billing and collections, information technology, and human resource matters. Over the course of her 20 years at Health Watch, Donna progressed from Accounts Payable Clerk to Chief Financial Officer.
