Melanie Griswold, Supportive Services Coordinator
“My name is Melanie Griswold; I am a supportive services coordinator serving Northwest Medical Specialties. At NWMS, I have the opportunity to work with patients and their support teams to assist with navigation, support and resources they may need during their life’s journey while being patients at our clinics. This may look different for each patient, finding resources to help pay for utilities, rent, or food insecurity. I’m here to walk with you through this journey.
I realize this journey can be frustrating at times and may have ups and downs and my hope is to help support patients during this time to help remove potential barriers with care or resources and provide education of community programs available.
Please don’t hesitate to call if you would like to schedule a time to meet or would like to talk with me about how I can be a support for you through this journey. I look forward to helping you in any way that I can.”
