Career Path:
It is my belief that family medicine physicians need to be the driving force of change when it comes to de-stigmatizing mental health in society. We touch many lives, and have the power to normalize mental health struggles with conversation. These conversations need to occur in the office and out in the community. I have emphasized these principles throughout residency via community events as well as in office visits where I have been able to provide my patients with tools to navigate the stressors of life. I am honored to continue this journey in my new position at this residency program.
