Vadim Sitnyakovskiy, LCPC

I was born in Zavitinsk, Russia, in 1981, in the region of the river, Amur, where my father was stationed as an officer.  About ten years later, in 1992, my mother's side of the family and I had immigrated to the United States.

In DePaul University, where I had gone for my college studies, I had initially wanted to major in philosophy, as I was looking for answers about the world and our existence in it. One may say that I was going through a kind of an existential crisis, and existential studies seemed like the logical route to take. Alas, as I had soon come to understand, the component of scientific investigation was integral to my quest, and I had therefore ended up choosing psychology as my major.

After graduating De Paul, I went on to continue my education at the Northeastern University graduate school, where I had earned the degree of School Counselor. However, it was in the direction of clinical counseling that my heart desired to go, and I had thus pushed forward to pass the exam for “Licenced Clinical Professional Counselor” (LCPC).

In the end, I have learned that what is essential is to learn to believe in one's self and to engage in the appropriate activities to do so.  As it is said in the movie, Field of Dreams, "If you build it, he will come." That is what I wish for you, my dear reader, to find your dreams.
