Doctor of Osteopathic Medicine

Doctors of Osteopathic Medicine (DO) see patients, prescribe medications, perform surgeries, and deliver babies in hospitals, medical centers, and offices across the United States and overseas. Whether they are primary care providers or specialists, DOs use all the standard tools of modern medicine, but also have additional therapeutic modalities with which to care for their patients. Our students thrive in a culture of patient-focused care because they practice on a foundation of professionalism, benevolence, and respect. They understand that while they practice the art of medicine with their heads, they must never forget to use their hearts.

    About the College

    At the College of Osteopathic Medicine of the Pacific (COMP) and COMP-Northwest, we focus on one program, the Doctor of Osteopathic Medicine. This means we are 100% dedicated to helping you fulfill your calling to become the doctor you are meant to be. Each student journey is slightly different, because each student is different – yet our graduates obtain the same outcome beyond the DO title: Rooted in Humanism, you will find your authentic self – a place to heal with your head and your heart.

    We inspire, in a humanistic tradition, technically competent, culturally sensitive, professional and compassionate physicians who become lifelong learners.

    Rachel Battersby, DO2027
    Student DO of the Month

    “Rachel deserves to be Student Doctor of the Month because she is always spreading positivity amongst her peers and makes great resources for reviewing OMM. She makes a wheel of OMM techniques every block to help students review OMM before practicals. This allows students to test themselves on each technique randomly to enhance their learning and is very helpful! She even made one for the first year students! As Wellness Advocate for the DO 2027 SGA class, she organizes many events to relieve stress and make school more enjoyable! Examples include making candy grams for DO 2027 to spread positivity, organizing a coffee vendor to come to campus, planning a workout for students after class, and many more! Rachel loves to bake and is always bringing baked goods to school to share with her classmates as well!” more…
