Sandra Tinnesen, Chief Financial Officer 

Sandra has over 28 years of experience in the “Accounting World.”   

In 2002 she started working in the Credit Department at the Headquarters of Oakley Inc. in Foothill Ranch, CA. By 2004 she ended up leaving Oakley and took a risk on relaunching a business and became the CFO of a company that manufactured a product in the baby & child industry, and she named it Savi Baby, LLC. 

Another opportunity came up in 2005, and that’s when OC Fitness Source, Inc/EWOT, was launched!  Sandra ran Savi Baby and OC Fitness Source/EWOT between 2005-2019. 

At the beginning of 2020, she decided it was time to close down Savi Baby and focus on OC Fitness Source/EWOT.  After all, she’s very passionate about Health and Wellness.  Sandra made a promise to her mother right before her mother passed away in 2010 from pancreatic cancer that she would dedicate her life learning and sharing anything and everything she knows about Health & Wellness.  One of her hobbies is baking and cooking Keto recipes! 

Sandra lives in Orange County, CA.
