Keith and I can’t thank you enough for the amazing job you did at Jared’s Bar Mitzvah. The kids and adults had a blast with you! You sure do know how to get a party going. We will definitely be in touch in 2019 as we plan Noah’s Bar Mitzvah! Thanks again!

Dear Marc: Planning a party is a several months exercise, but the party itself is only a few hours long. So, getting to know you the past few months has been part of that experience for us. It without saying that you have an incredible amount of energy, and everything you do this innovative and fun. Marc, thanks again for everything you did. It is been such a great pleasure getting to know you, and we look forward to many more things together in our future.

It is indeed a pleasure for me to write this appraisal recommending Marc Rosenberg as an entertainer for any family, corporate or social event. I quickly learned of Marc’s passion to make people laugh and put a smile on their face. He is a gifted entertainer with a generous and energetic heart.

Marc entertained the guests of the Johns Hopkins Relay For Life, our signature activity, which is dedicated to honoring present and former cancer patients. Marc Selflessly gave of his time, talent and expertise to amaze our more than 500 guests. Shortly after Marc began to shake his stuff a crowd swarmed around him. Children were pushing their way through trying to see what the man serving lemonade was doing. For well over an hour Marc Rosenberg made our cancer patients and survivors laugh, smile and be grateful for every minute of every day they live.

In all, I highly recommend Marc Rosenberg as an entertainer for any occasion. I look forward to hearing positive news of Marc’s accomplishments and success. Please feel free to contact me if you have additional questions on Marc’s behalf. Thank you.
