Every day, human beings are constantly thinking about their money.  Money can cause stress and anxiety…and it can create freedom.  Sarah Miller started working with individuals and companies over a decade ago, to guide them to financial freedom.  She joined Northwestern Mutual in 2008 (amid another financial crisis) and is committed to growing a practice and a team that can help people gain confidence in their relationship with money.  

Sarah is engaged to Scott, her forever best friend.  They have a Corgi named Penny Lane and is unashamedly a crazy dog mom.  Sarah’s plans are always to soak up as much beautiful Colorado sunshine as possible - while also attempting to touch, feel, and explore all of the amazing places in this world.  Sarah’s fundamental philosophies are: drink all the water, exercise = great mental health, great coffee is a treasure, and trusting in God will lead to a life without limits.
