About Us

Clear Blue Swimming Pool Service, Inc., owned and operated by Mark O’Brien, is a full-service residential swimming pool company servicing the greater St. Louis area. We offer everything from pool openings to service and maintenance to closings, including small to very large, detailed rehab jobs. And installing new vinyl liners is one of our specialties!

Mark is an APSP-II trained and certified technician and has been in the swimming pool business for well over 20 years.

Our staff is well-trained, courteous and knowledgeable. Our lead service technician, Dustin Tullock, is an APSP-I trained and certified technician and has been with us since 2004.
