After serving as law clerk for U.S. District Judge Robert Varner, Rhon began practice in Birmingham with the firm of Starnes & Atchison. Rhon joined Beasley Allen in 1994 and now manages the Toxic Torts section of the firm. He is currently involved in toxic exposure cases in Alabama, Colorado, Florida, Georgia, Missouri, New Jersey and Tennessee.

Rhon is currently investigating cases related to the BP Oil Spill in the Gulf of Mexico. On April 20, 2010, a massive offshore oil rig known as the Deepwater Horizon exploded and caught fire in the Gulf of Mexico, about 50 miles from Louisiana's coastal wetlands, killing 11 workers and injuring 17 others. Firefighters and the U.S. Coast Guard fought for 2 days to contain the fire, but the rig sank on April 22. Since its sinking, the spill site has continued to leak oil into the Gulf, creating an environmental and economic disaster affecting the entire Gulf Coast region.

Beasley Allen has currently filed a number of lawsuits in District Courts in Alabama, Florida and Louisiana to help protect businesses and individuals harmed by the oil spill. The first suits were filed on behalf of Plaintiffs in the commercial fishing and restaurant industries, as well as on behalf of Gulf Coast real estate management companies, a commercial charter fishing guide, a commercial fishing deckhand, and a SCUBA diving business. Recently, Beasley Allen also filed its first case in state court, on behalf of property owners whose investments have lost value as a result of the oil spill, and has filed a personal injury lawsuit on behalf of people injured by chemical dispersants used in oil cleanup efforts.

Rhon has been involved in cases for Beasley Allen where the settlements or verdicts have totaled over $1.1 billion dollars. Cases of note:
