KATHRYN K. THEOFILOS, ESQUIRE, Owner
While Kathy Theofilos dreamed of marrying the luxury of a spa with state-of-the art fitness classes and programs for children and adults, the blueprints for Oxygen Health & Wellness—Palm Beach County’s hottest health and wellness club for adults and children—were born. “I was tired of the same old crowded, dirty, workout center scene and wondered why the best of the spa, design and fitness worlds couldn’t be joined under one roof,” says Theofilos of her 10,000-square-foot North Palm Beach wellness club. “What you see here is everything that was on my wish list of the perfect club.” Kathy brings an eclectic mix of unique management and leadership skills and life experience to her position. She is president of Theo Development, Inc., a real estate development and management company and vice president of SNJ Properties, Inc., General Partners of Theo Realty Investors. Additionally, she is an accomplished attorney, having earned her J.D. degree with highest honors from the Cecil C. Humphreys School of Law.
