    I chose family medicine because I enjoy treating newborns, to great grandparents, and if I get to know the entire family, then that is even better. I try to focus on preventative health, and hope to develop a sense of teamwork with my patients.

    I recently moved from Ukiah with my husband and children, and we are enjoying beautiful Sonoma County.

    *Dr. Kylstra is amazing - smart, kind and caring.
    I have told others how wonderful and caring my dr. is and I believed have gone to her because of that. 9. I believe she saved my life. I love her. 10. I have.
    I really like Dr. Kylstra, she is very kind, reassuring and sympathetic.
    Good experience.
    This was my first visit with *Dr. Kylstra and I recently moved to California & was looking for a new GP.
