About Catherine Sundsmo, MD

I practice as a team with Dr. Jade Grimm, and we work together to provide you excellent care. I chose to pursue family medicine for the opportunity to interact with individuals of all ages. I provide treatment for a wide range of diseases, offer education on preventive care and build quality relationships with the people I care for. In medicine, I feel that there is a balance in providing education and reaching decisions between patient and physician. I believe in focusing on preventive medicine, a healthy lifestyle and effective communication when treating patients. I aim to provide kindness, intelligence and compassionate care at all times. I enjoy spending time with my family and our dogs when I am not working. My hobbies include running, gardening, cooking, hiking, camping, playing soccer and traveling.

Dr Sudsmo is incredible at patient doctor relationship - she remembered about my child and asked how we are doing, she inquired just enough to make me feel seen and give the sense that I mattered. I like my doctor's ability to connect what my symptoms/experience is to the proper testings and possible causes. Also she listens well and in general extracts the important details of my experience when I tell her how I am doing,
