In April 1990 Mr. Dennis DiMarco, #19980 and Mr. Ronald Raver, #20711, both Third Degree Black Belts (Sam Dan) who had began their training under Masters Young H. Kwon and Young K. Kwon, opened the Tang Soo Do Institute at a small storefront in Glenolden, Pennsylvania. The first official class was held on April 16, 1990 with ten students in attendance. The Logo was a drawing of Two Dragons (one representing each instructor) holding the Um-Yang Symbol in the center. It was adopted from the Black Belt Club Name and Logo from Tang Soo Do Karate Academy where they were then training under Master Mark Causerano on Haverford Avenue in Philadelphia. On May 5th, 1990, there was an Official Grand Opening where the flags and portraits were hung. There were 19 students at this time. Mr. DiMarco and Mr. Raver put on a small demonstration, and the East Coast Demo Team also performed. Classes were five days each week. In 1990 at the World Championships held at the Philadelphia Civic Center, the school performed very well bringing home many trophies, sometimes sweeping the divisions. Things moved along smoothly and in 1992 Mr. DiMarco was invited to the Masters' Clinic and was successful in his promotion to Fourth Degree Black Belt Master (Sah Dan) in October 1992. In May 1993, Tang Soo Do Institute had their first Black Belts. Among them was Mr. Joseph Centrone, #025080. Mr. Raver tested for the rank of Fourth Degree Black Belt Master (Sah Dan) in 1994 and was successful, receiving my ranking at the World Championships in Orlando, Florida that Summer.

In the Spring of 1996 Master DiMarco and Master Raver had grown apart and decided to dissolve their partnership in the Tang Soo Do Institute. Master Raver retained the studio location in Glenolden and incorporated the new Studio (Dojang) as Pal Che Tang Soo Do meaning "Selection of the Best", using a "White Tiger in Water" drawing by Karen Philips from Florida as the logo for the new school. Master DiMarco moved and opened a school with the same name, Tang Soo Do Institute, on MacDade Boulevard, but it only remained open for several months until he moved to his current location in Pennsburg, Pennsylvania.

The Studio (Dojang) continued to grow, and in 1999 Mr. Raver retired from Sunoco to operate the school full time. It was at this time when we began Kids Karate Programs for young children called Tiny Tigers. In October 2002, after having been promoted to Fifth Degree Black Belt (Oh Dan), Mr. Raver retired as Owner of Pal Che and Mr. Joseph Centrone assumed ownership of the school. Under his leadership, the school reached its largest student population of 100 students in early 2004. The school facility expanded from just one training room, an office, and a small lobby to its much larger current size with many renovations taking place for more room for students and parents. Mr. Vincent Melchiorre, #025050, a close friend of Mr. Centrone, joined the Pal Che from Shin Karate in Philadelphia as a weekly Instructor. In October 2005 Mr. Centrone and Mr. Melchiorre, were promoted to Fourth Degree Black Belts (Sah Dan), receiving their Master's Ranks the following year. In 2008, Master Melchiorre opened a Club (Dojang), Dragon's Den Martial Arts, in his community in Voorhees, New Jersey. In 2008, students Mr. George Celona, #030090, and Ms. Angel Evangelista-Celona, #031088 branched off to open their own Studio, Impact Martial Arts, in Cecil County, Maryland. After years of growth and expansion, Master Centrone retired in May 2011, turning the school over to longtime student, studio manager, and head instructor Mr. Nicholas D'Amato, #036548, who recently earned his Third Degree Black Belt (Sam Dan).

In all, over 900 student have signed up and trained at this small school with little parking in Glenolden. There have been over 70 Black Belts and several who are on their way to Master Rank.

In 1968 Master Jae Chul Shin came to the United States of America as a Representative of the Korean Soo Bahk Do Association.  He formed the United States Tang Soo Do Federation in Burlington, New Jersey that same year.  After over a decade of expansion, Master Shin decided to restructure the organization to meet new international demands.  A Charter Convention was held on November 13th-14th, 1982 in Philadelphia, Pennsylvania, which founded of the World Tang Soo Do Association.  At the convention a new constitution was passed, a new logo and insignia were selected, the uniform and belt system were revised, and new organizational standards were adopted.  Also at this convention, Master Jae Chul Shin was recognized as the Grandmaster of the World Tang Soo Do Association.

The World Tang Soo Do Association is divided into 22 different Regions, each with its own Director and Events.  The World HeadQuarters was located on Oregon Avenue in South Philadelphia, Pennsylvania, which is in Region 8.  The Association has taken nine official expedition trips to Korea and China so that students can learn about the roots of Tang Soo Do and train where the Art was founded.  The World Championships have been held every two years since 1986.  In 1990, GrandMaster Jae Chul Shin envisioned a new home for the organization where there would be a permanent place where all World Tang Soo Do Practitioners could visit and train, and the Building Fund was created for a new HeadQuarters.  After many years of dedicated searching, in 2012, the World HeadQuarters will relocate to Burlington, North Carolina.

The World Tang Soo Do Association stands for three mottos, Traditionalism, Professionalism and Brotherhood/Sisterhood.  These mottos evoked the interest of many martial artists, whose genuine interest was in studying the Art and was not sport orientated.  The World Tang Soo Do Association has become one of the most respected traditional martial art organizations worldwide, with over 700 schools present in more than 30 countries as well as over 100,000 members and 15,000 Black Belts.
