Sonny was born in Texas.
Although never shown on-screen, Sonny returned to Salem in 2007 with his parents and brothers. Along with his siblings, he attended Salem High School. His time in town was short lived, however, and by January 2008 the entire family moved again - this time to Dubai.
Sonny returned to Salem in June of 2011. He wanted to return to Salem to tell the members of his extended family that he was gay. Justin and Adrienne had known for years, but Sonny wanted to tell Victor and the rest of the family. All of his relatives were supportive. Sonny only encountered discrimination from T, one of Gabi and Will's friends, but the rest of Sonny's friends stuck up for him. Despite T's cruelty, Sonny even tried to reach out to T to stop the bullying.
After a brief internship with the Salem DA, Sonny embarked on some entrepreneurial opportunities. Will, Chad, and Sonny decided to launch a website surrounding Salem U's sports teams. The website was a huge success and quickly gained visitors. However, one day Chad noticed some suspicious activity on the message boards. It appeared that someone was using their website to give odds in an illegal gambling operation. After following a trace on the IP address, the boys learned that their entire website had been hacked and was a front for a gambling ring. The boys attempted to shut it down, and did so without Melanie, Gabi, or Abigail knowing and thought everything was fine.
But, the trouble wasn't near over for them. When the men behind the gambling ring found out that the boys had shut down their website, they kidnapped Melanie and Chad and held them hostage until Will and Sonny got the site back up. While Gabi and Abigail went to track down Melanie and Chad, Will and Sonny worked on getting the site back up. Luckily, Melanie, Chad, Abigail, and Gabi were not harmed. But, Will finally did talk to Rafe, Bo, and Hope. The men behind the gambling ring were arrested.
Sonny decided to open a coffee shop in Salem, "Common Grounds," a place where people of all different lifestyles could feel comfortable. Chad partnered with Sonny, but Will did not want to participate. Sonny noticed that Will was withdrawn. Will was starting to question Will's sexuality. Trying to be as supportive as he could, Sonny often invited Will out with Sonny's friends. Eventually, Will came out. Sonny was one of the first people Will told.
Soon, Sonny developed feelings for Will. When Sonny suprised Will with a kiss, Will rejected Sonny. Sonny was unhappy, but not ready to give up on Will. Eventaully, Will returned Sonny's feelings and the two began to date.
Sonny and Will ran into a little opposition from Lucas, who wasn't comfortable with his son being gay. Lucas and Sonny butted heads several times, but Sonny made it clear to Lucas that he loved Will. Lucas backed off and supported Sonny and Will.
With their relationship going so well, Sonny didn't think twice about lending Will money when Will came to him. However, Sonny did not know that the money was for Gabi's abortion. (Gabi was pregnant with Will's child.) Gabi did got go through with the abortion, but Will did not tell Sonny about the baby.
