Kayla Clark Licensed Professional Counselor, LPC
I am a Licensed Professional Counselor in the state of Texas with a masters in Counseling and Development from Texas Women's University. I have worked with a variety of clients including those in crisis, depression, anxiety, mood issues, and general trauma. I love to work with young adults and teens, specifically those who enjoy a more direct approach, with a twist of humor and sarcasm. I have also worked with fostering, adopted, and in state custody adolescents. I have special training in substance use, incarcerations, rehabilitation, and veterans in the court system.
As a Solution Focused Therapist (SFT) I aim to create realistic goals for us both to open, work on, and achieve through out the therapeutic process. I also draw from Cognitive-Behavioral Therapy and use CBT techniques to address someone's needs by encouraging positive self-thoughts and reframing.The counseling journey can be really tough, and it's important you find the right fit. I enjoy learning about each client individually, while empowering change within. I am here to provide support through compassion and empathy each step of the way!
David H. Laubach, MS, LPC
I am a licensed professional counselor in the state of Texas. I earned my M.S. degree in rehabilitation counseling at the University of North Texas. Before coming to North Pointe Psychiatry I worked at Grace Counseling Center in Lewisville, Denton County MHMR, West Texas Counseling &
Rehabilitation, and the vocational rehabilitation division ofthe Texas Workforce Commission. My therapeutic experience mostly has been with the problems of depression, anxiety, substance and behavioral addictions, relationship and work problems, adjustment to aging, and counseling couples. My clients have ranged in age from teenagers up to people in their 80's.
My theoretical orientation is primarily based in Cognitive-Behavioral Therapy, but therapy is also personalized to fit the needs of individual clients and the problems that they are seeking to solve. I see each person as unique with his or her own path to walk in life. Life is diffcult, but there is still much joy to be realized and enjoyed. My goal is to help each client solve problems and to grow and learn from the therapeutic relationship that will help and prepare them to live more fulfilling lives after counseling has ended.
