Ukrainian engineers were an energetic force in the drive to build Ukrainian community credit unions. Several UESA members manned key leadership positions in the credit unions.

UESA branches located in areas with high concentrations of Ukrainians, such as New York, Detroit, Philadelphia, Chicago and Los Angeles, sponsor annual events such as debutante balls. These events benefit the entire community and are especially popular among younger Ukrainians.

During the 50 years of the Society's existence, the highly qualified professionals who make up the Society's membership have contributed greatly to science and technology in the United States. Members of UESA have published a large number of technical studies, as well as having obtained numerous patents. Most of the Society's members also belong to American and international professional organizations. They often lecture at scientific and technical conferences throughout the US and abroad.

UESA has counted and still counts a large number of distinguished scientists in its ranks, people such as Dr. Borys Ivanyckyj, Dr. Volodymyr Timoshenko, Dr. Stepan Timoshenko, Dr. Oleksander Smakula, Dr. Alexander Hranovskyj, Professor Alexander Kovalenko, Dr. Mykola Efremov, Dr. Oleksa Bilaniuk, Dr. Volodymyr Minkovych, Dr. Mykola Zajtsev, Dr. Joseph Kharyk, Dr. Osyp Andrushkiv, Dr. Alexander Serafyn, Dr, Volodymyr Kosonotskij, Dr. Mykhajlo Yaremovych, Dr. Lubomyr Romankiw, Dr. Lubomyr Onyshkewych and Mr.Mykhajlo Korchynskyj. UESA is proud to have counted such a person as the engineer and poet Evhen Malaniuk among its members.

Among the architects in UESA' ranks are those who designed many Ukrainian churches in the US and Canada. Members of UESA were also the designers of the UNA's high-rise building in Jersey City, NJ (the previous location of its headquarters, currently in central NJ).

Well known among civil engineering design professionals was the company owned by Myron Lepkaluk and staffed by chief engineer Evstakhij Yarosh. Many of the projects completed by this firm were of a complicated nature, including several monumental bridge structures such as the bridge over the Mississippi River in Luling, LA.
