Dawn is currently training to become an Enrolled Agent with the IRS, which will allow her to better serve clients by representing them before the IRS.

Dawn was born in Kansas, but grew up in Michigan, where her Midwest ideals of loyalty and hard work were instilled. Dawn first moved to the Sarasota area in 2006. She briefly moved back to Michigan from 2013-2015, but quickly came to realize that Florida was where she needed to be.

In her free time, Dawn enjoys reading, watching movies, and visiting the beautiful beaches Sarasota has to offer. While she currently lives in Sarasota with her husband and 2 grown sons, Dawn makes frequent trips back to Michigan to visit her daughter and newborn grandson, along with other family there.

Ron Drzewucki

Certified QuickBooks ProAdvisor

Ron Drzewucki graduated from Florida State University in 2018 with a degree in Finance and a double major in Economics. In the following year, he decided to continue his education at FSU in pursuit of becoming a Certified Public Accountant. While taking his classes, Ron worked for a payroll company where he was able to put his education to use. He is also a Certified QuickBooks Pro Advisor, and has chosen Sterling as his home while working towards his certification. Ron’s heavily analytical educational background in combination with his more recent exposure to accounting gives him the expertise necessary to advise business owners across many industries.                                                                 
Ron originally moved to Sarasota from St. Louis Missouri in 2005. He took a brief Hiatus while attending FSU where he was able to foster a love for rock climbing and become a registered yoga teacher; however, the beautiful beaches along Florida’s west coast couldn’t keep him away. Ron still finds himself practicing yoga and staying active, but he has found passion driving him to spend the majority of his time chasing his goal of becoming a CPA.
