Military veteran. Healthcare professional. Small business owner. Fighting to bring accountability and common sense back to Washington.

L. John MacKenzie is a military veteran, healthcare professional, and small business owner running for Congress to bring accountability, discipline, and common-sense leadership to Washington.
After 10 years of service in the Marine Corps and 15 years of service in the Air Force Reserve, John continued serving his community on the front lines of healthcare, working directly with individuals and families navigating complex medical and mental health challenges.
