He played college baseball at Reinhardt University before being transferred to Georgia State University where he was a member of Kappa Sigma fraternity. He graduated with a degree in Sociology which featured an emphasis on consumer behavior patterns.

In 2016, he started Team Kimberley which has quickly grown to become one of the Buckhead office's top teams.

Kristen Greifzu
was raised in the sunny side of Venice, FL where she began her real estate career and became licensed in 2003. She started out in residential and then when the market plummeted she ventured to commercial leasing and sales where she continued until 2012. Kristen and her family migrated to North Carolina to be closer to family and then in 2014 moved to Douglasville, GA. She obtained her GA license in 2015, so she could continue her love for real estate. Kristen picked back up with commercial leasing and sales at a company in Sandy Springs. She thrives off of challenges and learning more! As she wanted to expand her knowledge and experience in real estate, she started a new journey with Team Kimberley at Berkshire Hathaway, and is getting reacquainted with residential as well as bringing in some commercial to the team!

Kristen has three children, Joselyn, James, & Tyrone, and they are getting ready to add another little one to the family in February 2020. She enjoys spending time with her family, sunning on the beaches, and traveling. She is full of energy and adds flavor wherever she goes!
