No, Lauren Holtkamp is not married - she's still single. However, she is also a very private individual, so it is possible that she's dating someone "behind the scenes" without anyone knowing about it.
But you can clearly see there is no ring on that finger, despite being 33 years of age.
She's been refereeing basketball games since 2004, and made her way up from the D-League, so that hasn't left much room for relationships .
As for marriage though, it's still on the to-do list of this female NBA referee. She's only the third full-time female to referee in the NBA, but don't think she gets any preferential treatment!
Recently, players and coaches alike have been critical of Lauren Holtkamp. The Clipper's Chris Paul was VERY critical of her during their game with against the Cavaliers.
