Traditionally known as a nationally recognized political thought leader, Christian Archer’s latest endeavor is perhaps the most ambitious of his career. He has created a company that is indeed a unicorn and is on target to become a leader in the mass tort industry.

Combining his political experience with his natural entrepreneurship ability, he has launched Perfected Claims, a company specializing in handling Mass Tort Claims. The company’s differentiation is its ability to be nimble while giving clients the one-on-one service that individuals who have been injured and or harmed, the kind of one-on-one attention they deserve when experiencing what, in many cases, is the worst disaster of their lives. Through his efforts and the efforts of the team he has built at Perfect Claims, clients will have a partner in navigating complex litigation and the opportunity to seek justice when wronged.

Christian Archer’s journey from a political thought leader to a multifaceted entrepreneur and artist reflects his relentless pursuit of success and impact across various fields. Christian’s exceptional reputation and success in governmental relations led business leaders, professional organizations, and corporations to seek his expertise in developing strategic political relations. Fortune 500 companies, international corporate CEOs, NFL football teams, and various business leaders have all benefited from his understanding of local and state politics.

Renowned as “the closer” and “the go-to Democratic strategist for Texas,” Christian’s winning campaign track record has significantly contributed to San Antonio’s economic growth and viability. Notably, he successfully steered the passage of over $1.9 billion in city bond referendums between 2007 and 2012 and the record-breaking $850 million bond in 2017. The public overwhelmingly supported these campaigns, fostering genuine economic development in San Antonio.

Christian is the father of three and resides in St. Thomas, US Virgin Islands, with his partner Sandra.
