Founder and Sonographer

Stephanie Johnson is a Registered Diagnostic Medical Sonographer with over 20 years of experience working in a high acuity healthcare system in Seattle. She holds a Bachelors of Science degree in Diagnostic Ultrasound and is board certified in Abdomen, OB/GYN and Small Parts.

Stephanie believes in blending compassionate care with detailed high quality ultrasound services. She has a passion to bring ultrasounds to the community and make them more accessible to everyone. Stephanie recognized that patients were having difficulty with transportation issues, scheduling exams, and having them performed in a timely manner. She knew there was a better way for the community and as a result she created Grayscale Ultrasound.
