Grand Master Pablo Trajtenberg sa prv�kr�t stretol s Taekwon-Do v roku 1968, ke� sa chcel u�i� Karate. Na�iel �kolu, v ktorej sa mu p��ilo najviac a povedal si: "Mus�m z�ska� �ierny p�s a nez�le�� na tom, ako dlho to bude trva�". O t��de� nesk�r dostal z�pisn� kartu si myslel, �e do�lo ku chybe, preto�e tam bolo nap�san� �Taekwon-Do�. Ale sekret�rka mu povedala, �e je to K�rejsk� karate, a �e je najlep�ie! Od toho momentu sa tomuto �portu venoval non-stop.
Jeho u�ite�om bol Nam Sung Choi, jeden z pionierov Taekwon-Do pioneers v Argent�ne, ktor� tam pri�iel rok predt�m, v 1967.
Potom pri�iel okamih jeho prv�ho stretnutia s gener�lom Goih Hong Hi.
Trajtenberg bol uchv�ten� osobnos�ou gener�la a jeho zanieten�m pre Taekwon-Do.
�ierny p�s z�skal v roku 1971 a jeho nad�enie ho viedlo k �spe�nej v�u�be Taekwon-Do, �o sa dalo pozna� pod�a mno�stva z�ujemcov o jeho kurzy.
V roku 1973 spolu s �al��mi sa z��astnil sl�vnostnej ve�ere s gener�lom, odkia� m� fotografiu s venovan�m "v�nemu �tudentovi Taekwon-Do s prian�m v�etk�ho najlep�ieho".
Potom nasledovali roky rozdelenia Taekwon-Do a gener�l bol n�ten� sa pripoji� k WTF, �o viedlo Trajtenberga k bolestiv�mu rozhodnutiu, ktor� ho oddelilo od jeho majstra. A tak si v roku 1978 za�al dopisova� s �al��mi dr�ite�mi �iernych p�sov v Argent�ne a s gener�lom, �o vyvrcholilo pr�chodom majstra Jon Chang Kim-a, ako deleg�ta na podporu Taekwon-Do v Argent�ne.
V roku 1977 sa Trajtenberg nadobro vzdal �t�dia elektrotechniky na univerzite s cie�om naplno sa venova� v�u�be Taekwon-Do.V roku 1980 potom spolu s priate�om, s ktor�m sa poznal od �ias "bielych p�sov" otovoril �Centro Argentino de Taekwon-Do�.
V roku 1981 akt�vne spolupracoval na pr�prave majstrovstiev sveta v Argent�ne na �ele s majstrom sveta Javierom Dacakom a dostal sa bli��ie ku gener�lovi Choi Hong Hi, ke� za n�m cestoval a tr�noval pod jeho veden�m.Gener�l ho ve�koryso ubytoval v dome svojej dc�ry Sunny. Bola to nam�hav� cesta, ale gener�l mal st�le vyhraden� miesto pre t�ch, ktor� mali naozaj z�ujem o jeho v�u�bu.
Po�as rokov Trajtenberg nav�t�vil majstra J.C.Kim a tie� Si Ki Choi, Park Jong Soo a in�ch ve�k�ch majstrov.
Jeho najlep�� �iaci s� v ���asnosti u� dr�ite�mi 7. a 8. danov, nieko�k� z nich dokonca na medzin�rodn�ch postoch. Argent�nske Taekwon-Do sa teda vyv�ja a podie�a sa na svetov�ch turnajoch a glob�lnych aktivit�ch.

While attending ITF�s first IIC in Vienna as Argentinean delegate he obtains support for his country, which in 1986 permits the foundation of the Taekwon-Do Federation for the Argentine Republic �thus gaining autonomy from Korean predominance-, and in this institution he has acted as Secretary General till today.

In 1987 he has a difficult time upon General Choi�s visit to this country as there is a military dictatorship and the Korean embassy accuses ITF of being communist sympathizers, which forces Trajtenberg to shelter General Choi in his own home for protection, while transferring his family elsewhere.

He travels abroad to introduce Taekwon-Do in Bolivia, Brazil and Uruguay; Brazil being the country where he is faced with the biggest obstacles to expand Taekwon-Do. A lasting friendship is born between Trajtenberg and Tran Trieu Quan while sharing countless experiences impossible to summarize herein. Also with Wim Bos and with Clint Norman, all of them brethren united by their common passion.

In 1993 he concludes an intense task in collaboration, namely the translation of the condensed Encyclopedia into Spanish, following the guidelines and corrections from Taekwon-Do�s Founder.

In 1994 he is bestowed in Malaysia with one of the most important awards that the General conferred to only 9 of his Western disciples, the �Prize for Loyalty�, which he regards proudly as one of his top achievements.

Together with Tran Trieu Quan he actively participates as ITF delegate, therefore occupying a position of great responsibility upon the General�s death.

The rest is recent history and it may be claimed that he is now a happy man as President of ITF, always surrounded by good friends, Great Masters and Instructors and above all proud of his disciples, many of whom have become Masters. His closest circle is made up by Sonia and Vivian, his two sisters, and a wonderful wife: Liliana Ferreiro, with whom he has shared his life for 35 years and who has given him three sons: Alejandro, Luciano and Kevin. As he himself likes to point out, there is nothing else he can ask from life.
