About Us

Yleis Engerman, MS, LADCI, LMHC

Clients that are focused and motivated to get better, and are willing to put forth the effort to do so. Clients that are ready to dig deep and work on issues that are way past the surface. Clients who may not initially be in the contemplation stage of change, but knows that change is needed.

I am a Licensed Mental Health Counselor and a Licensed Alcohol and Drug Counselor. I specialize in Anxiety, Depression, Substance Use/Abuse, and PTSD. By implementing CBT, DBT, Motivational Interviewing, Behavioral Activation and other approaches tailored specifically to you, I can help you to regain functioning in need areas.

Its hard to go through tough situations, and it is even harder to go through these situations when you feel like you are alone and nobody cares and/or understands. I care, and I am willing to help you to work on these issues.
