When Arthur arrived in town a month later, he instantly drew attention to himself at a charity auction by outbidding everyone for the watch he had once given Michael. That same day, Arthur became the chief of staff at the hospital where Heather was a resident. His relationship with his two children was strained, and Heather even considered transferring to another hospital.

Arthur didn't like Dr. Scott Clark, another resident at the hospital, especially when he learned that Scott and Heather were seeing each other. Arthur did everything to break them up and got Heather's former college chum, Zack Kelton, a job at the hospital. He hoped that Heather would dump Scott for Zack, but that never happened. Arthur then assigned Scott to run a clinic in the poor section of town.

Things took a turn for the worse when Arthur performed an emergency surgery on Scott's father, Ben. Sadly, Ben died on the operation table. Although Arthur was genuinely devastated by this turn of events, Scott accused him of murder and punched him.

Meanwhile, Arthur dated Sophia Capwell and later Victoria Lane. After reconciling with his children, he left for a medical conference in Frankfurt.

Arthur didn't return to Santa Barbara until the following year. He came back at Heather's prompting because Michael was in jail for the accused murder of Leo Mitchell. Fortunately, Michael's name was soon cleared. Arthur started dating Sophia again.

By then, Scott had dumped Heather for Celeste DiNapoli, even though Heather was now pregnant. Because of this pregnancy, Arthur tried to get Scott and Heather back together. He was last seen when Heather's baby was born.
