I have been part of the formative and development stage in the tennis field specifically, of Agustín Cuéllar Lorberg. Likewise, I am a witness to his achievements from the beginning to the present. Agustín comes from a family with a great tennis tradition in Bolivia; who instilled in him a passion for this sport. Hence, he always showed commitment, good attitude, interest, fighting spirit, both in training and in competitions. His excellent technical, tactical, physical and mental conditions have allowed him to become champion in the different National Tournaments; in addition to having had outstanding performances in international tournaments. Those of us who know Agustín know that his talent was determined, good predisposition and human qualities; they will facilitate his journey towards the goals and objectives that he has set.
