My mission is to teach patients how better health habits can prevent many diseases.

It is a privilege to help people and establish long-term relationships with my patients. I believe that everyone's medical care should be individually tailored. We all have unique characteristics that need to be considered when deciding a treatment plan. Communication is paramount. Outside of work, I love exercising, working in my garden, and spending time at the Cape; however, most importantly I love spending time with my family.
 

My mission is to provide the best primary care for my patients to prevent disease. This includes regular follow up of chronic conditions and keeping patients up to date with routine screenings.

It is a privilege to provide primary care and establish long-term relationships with my patients. I believe that everyone's medical care should be individually tailored, and communication is key to providing excellent care. Outside of work, I love to spend time with family and friends. My hobbies include skiing, quilting and cooking. 

It is truly an honor to participate in the care and lives of my patients. My passion is driven by the bonds I build with my patients over the course of their lives and the enjoyment and satisfaction I hold in treating them to be as healthy and pain free as possible. It is to the extent that I feel that  "I truly have the best job in the world."
