Warren initially studied theater arts and direction at UCLA and later graduated in interior design at the Fashion Institute of Design and Merchandising. He was working at an upscale showroom and design studio when his facility with style prompted a client to enlist him in designing her residence. This led to further commissions from an array of clients who clamored for his intrinsic panache. Through the years, Warren has integrated his theater background into his work not only in lavishing character and depth to designs but by formally unveiling finished projects with the dramatic flair of staging event receptions.
