Helping his patients maintain the highest quality of life possible is his main goal. Dr. Murashige chose medicine as his career because it gave him the opportunity to help others. It has been extremely rewarding for him knowing that he has been able to use his skills and training to make a positive difference in his patients' lives.

    *Dr. Murashige is very through, friendly & easy to talk to about anything.
    *Dr. Murashige is the BEST doctor.
    I have recommended Dr. Murashige to many of my friends and we all agree he embodies all of the above.
    Dr. Murashige is very kind and caring. He treats me as an intelligent person. Many other doctors "talk down" to their patients, Dr. Murashige does not.
    *Dr. Murashige is our family doctor. My husband & my son are very happy to see him too. He is very kind, patient with all of my questions & concern. Like I stated in the previous questions, I've seen him for more than 10 years. He is very knowledgeable & always put the well being of patient first. I would love to continue seeing him every year for my physical check up! He is the best dr.!
