I'm  Lynn Taylor

I am the Chief Clinical Officer for North Valley Vein Specialist. I moved to Arizona in 1989 from Long Island, New York after getting married to my husband, Richard. I currently reside in Glendale, AZ with my two amazing children and five dogs. I started healthcare in 1988 and became a surgical technologist/private scrub tech in 1992 and have traveled to several valley hospitals. I began my new and exciting path into vascular surgery 31 years ago and have been in love with the field ever since. I have been working with Dr. David Smith for the past 13 years. Outside of my career, I enjoy spending quality time with my family, going antiquing and traveling to new and adventurous places. I have always believed there is too much world out there to always be inside.
