I am the second youngest of four siblings, born the city of Houston, Texas. My early years were shaped by the warmth and culture of the South, where family and community played a central role in my upbringing. My formative years were largely spent in Cleveland, Ohio, a place that grounded me with its strong sense of resilience. Life later took me to Las Vegas, Nevada, where I spent five years experiencing the city’s unique energy and diversity. Eventually, I made the decision to move to California in search of greater opportunities and a more temperate climate, embracing the Golden State’s promise of growth, diversity, and sunshine.
