Addiction therapists & psychiatrists in Saint Peters, MO

Everyone has the power to grow, heal and improve their life. Maybe you are feeling stuck due to symptoms of depression or anxiety or are feeling overwhelmed by being in a difficult season of life. Therapy can help you process what you have been through, better understand the patterns keeping you stuck, and build healthier ways of coping so you can feel more grounded, resilient, and in control of your life again. Having a seasoned and trusted clinician alongside you can make all the difference in moving you towards your goals. For almost 25 years, I've partnered with individuals experiencing depression, stress management, anger management, and PTSD so they can regain emotional balance, strengthen their relationships, and create healthier, more fulfilling lives. Working with adolescents and adults, I strive to provide a compassionate, supportive space where you feel heard, respected, and empowered to take meaningful steps toward lasting change.

Great to meet you!

I offer a wide range of therapeutic services, including individual therapy for adolescents, and adults. I specialize in creating a supportive environment where clients can explore personal challenges, improve communication, and work toward healthier relationships. My experience extends to school counseling, working with high school students to foster emotional resilience, addressing academic stress, and promoting mental well-being. I facilitate group sessions, providing participants with a collaborative space to connect with peers and developing coping strategies for navigating life’s challenges.

I believe every person deserves to feel heard, understood, and supported. With more than 20 years of experience in the mental health field, I have had the privilege of working with children, adolescents, adults, couples, and families facing a wide range of challenges. I earned my Master's Degree in Community Counseling from Pittsburg State University and am a Licensed Professional Counselor and Missouri Associate Alcohol Drug Counselor II.

Throughout my career, I have worked in juvenile and adult justice systems, drug courts, schools, and community behavioral health settings. These experiences have given me a broad understanding of the many factors that influence emotional well-being and personal growth. I work with concerns including anxiety, depression, ADHD, grief, anger management, substance use, relationship challenges, and adolescent behavioral issues. My goal is to provide a supportive, nonjudgmental environment where clients feel comfortable exploring their concerns and building a healthier, more fulfilling life.
