Kelly C. Swann, MA, LCPC, NCC

Everyone needs help navigating life’s issues and complexities from time to time. Sometimes these challenges can lead to feelings of anxiety, depression, or frustration. I want to help you on your personal journey as you traverse life’s obstacles.  I am confident that each of my clients hold the capacity to overcome adversity, make healthy life choices, and lead happy and productive lives.

My therapeutic approach is tailored to best serve my client’s personal needs. I utilize a holistic approach to therapy, which considers the entire human being and collective life experiences. My practice includes physical and spiritual context as well as mental well being.

I have worked with a broad range of populations including but not limited to Depression and Mood Disorders, Addiction, Eating Disorders, Grief and Loss, Trauma, Relationship Issues, Self Esteem Issues, and Life Coaching. 


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.
