I have immediate openings for in person or telehealth appointments, including evening.
With over 20 years of experience, I have seen many people overcome challenges and regain hope. My approach is down to earth, while also giving you concrete strategies to help you make the tangible changes you want to see. I work with individuals aged 12 through older adulthood on a variety of issues, including those struggling with anxiety, depression, stress management, or life transitions.
Having strong, healthy coping skills can help you feel back in control of managing life again.
I am passionate about helping people find solutions to help them manage anxiety, depression, and stress in healthy ways. I also have expertise in substance use and addiction counseling for alcohol, marijuana, and opiates. I can provide substance abuse evaluations for the courts, employers, or school systems.
I use evidenced based, client centered approaches drawing on cognitive behavioral and motivational models. In counseling, clients develop the tools to challenge unhealthy thinking patterns, regulate their emotions, manage stress and increase confidence.
