I am a board-certified Psychiatric Mental Health Nurse Practitioner and have recently joined Denver Wellness Associates and I look forward to meeting you.
I became interested in psychiatry during my time working as a nurse in Colorado’s Western Slope. I have a holistic approach to care, and mental health issues cause pain and are just as important as our physical health! Living in small towns, I realized how access to mental health services was seriously lacking. Moving to Denver 8 years ago helped me understand that the problem is widespread, even in the city. I enjoy working with clients of all ages. I value honesty and collaboration as we work to help you meet your mental health goals.
I provide medication management, transcranial magnetic stimulation (TMS), ADHD testing, and genetic testing within the practice environment.
