Personal Interests

Dr. Mioduszewski enjoys spending time with her husband and three daughters, including identical twin girls. They embrace the great outdoors - from hiking and tennis to skiing. They also love exploring new restaurants and trying out new recipes at home. Travel is another favorite activity, but for now, Dr. Mioduszewski says she needs to live vicariously through her patients until her children are older. She is excited to have moved to the beautiful Pacific Northwest.

Practice Philosophy

“There is nothing more enjoyable than getting to know my patients long-term, making them feel comfortable, and delivering exceptional dermatological care. It is my goal to execute leading-edge, evidence-based medical care in dermatology. I pride myself by staying current with the literature and attending conferences on a regular basis to provide the best medical care possible.”

“Communication is key in the patient-doctor relationship. I look forward to listening thoroughly to understand their concerns and needs so we may come up with a management plan that fits each individual.”
