I have worked in the healthcare field for over fifteen years, with a strong background in emergency medicine, and behavioral health. The last 15 years have prepared me to continue to be a leader in the profession.
I am a dedicated mother, wife, daughter, sister, and friend. In my free time I enjoy cooking, traveling, and getting back into running.
I have excellent clinical skills, empathy, and an attentiveness to detail. I am a patient advocate with strong interpersonal skills.
Attention, impulse control, and trauma-related issues are often misunderstood, stigmatized, and poorly treated. With time and treatment, patients who are affected learn to recognize and compensate for their symptoms. Self-acceptance brings appreciation for their own energy, strengths, and resilience. Many continue to exciting lives of high achievement and satisfaction. It is my privilege to accompany you on this journey.
I believe we all need to be heard and treated with respect and dignity. Treatment involves us working together to get the best results.
