Elite Tennis Coach | Former ATP & ITF Ranked | Founder of Dalisay Management Athlete Wellness

Diego Garcia Dalisay is the founder and visionary force behind Dalisay Management Athlete Wellness, an organization dedicated to the comprehensive development of athletes through a fusion of performance, education, and well-being. As a former ATP-ranked competitor and internationally trained coach, Diego brings a rare blend of personal athletic achievement, global perspective, and transformative mentorship to his work.

From an early age, Diego made a name for himself on the international tennis stage. Recognized as one of Spain’s most promising junior talents, he achieved professional status at 15 years old, earning his ATP ranking. His playing career took him across the globe, competing in ITF juniors, Futures, and Challenger events and representing both Spain and the Philippines at a high level. In both junior and men’s divisions, he consistently maintained top national standings and was regarded as a formidable presence on the ITF circuit.

Diego’s academic and collegiate journey reflects his commitment to balance and resilience. As a standout at the NJCAA level (Tyler Junior College), he rose to become the nation’s number one doubles and number two singles player, earning All-American honors and claiming back-to-back titles at the ITA Regional Championships. These accomplishments led to a full athletic scholarship at the University of Hawaii, where he completed his Bachelor of Arts in Communications after returning to higher education following a ten-year hiatus from academic life.

His coaching experience is both broad and elite. Over the past five years, Diego has trained a diverse range of athletes, including developing juniors, ITF, ATP, and WTA professionals, as well as Davis Cup players and NCAA Division I student-athletes. In his role as a traveling ITF coach, he has helped players secure coveted university scholarships and thrive in elite competitive environments around the world.

Diego’s coaching philosophy is deeply rooted in holistic development. He emphasizes technical precision, psychological strength, and physical sustainability, tailoring programs that integrate performance analytics, individualized mentorship, and a strong foundation in wellness practices such as conditioning, recovery, and nutrition. Central to his approach is a belief in cultivating joy and purpose in the training process, an ethos shaped by his own journey through the highs and hardships of professional sport.

Following two reconstructive elbow surgeries that brought his playing career to an early close, Diego discovered a deeper calling in mentorship. Today, he channels his love for tennis into empowering others, using his personal story as proof that setbacks can become the source of strength, growth, and reinvention.

Fluent in English and Spanish, with conversational fluency in Tagalog, Diego continues to work with athletes globally, offering coaching, consulting, and athlete development across both in-person and digital platforms. His work reflects a lifelong mission: to build strong, self-aware athletes prepared not only to compete, but to lead, inspire, and thrive beyond the court.
