“In a world where there is absolutely no room for error, you can count on Harry Karr and his team to execute perfectly.  His staff is attentive to your guests needs and whenever Harry is on the job you have the added peace of mind knowing that things will be taken care of so that you are free to focus on other areas of your event. ”

“I have had the good fortune of working with Harry and Ray Karr, owners of Sovereign Services, for approximately 10 years with the last six at the Hotel ZaZa Houston.  Harry is the managing principal for our account and does an amazing job retaining quality staffers – the key to guest service in our business.  In addition, Harry is always on site for the very large events and has recently infilled his management ranks with quality additions.  Sovereign Services provides the best service and follow up that I have been a part of in my 27 years in the business.  They are not the cheapest but they are fair and extremely talented.  I have figured out through a few hiccups in past relationships that the cheapest is not always the best.  I wholeheartedly recommend Harry, Ray and Sovereign Services.”

“Sovereign Services has displayed the ability to handle our large Hotel valet services at the Hilton Americas-Houston.  Truly challenging at times, but Sovereign through  its capable and excellent management has provided the resources and commitment to improve this very important hotel service.  They continue to strive for excellence and their performance speaks for itself.  Joe Palmieri, General Manager”
