Customer Accolades

Mike and Rhianna DeAngelo; Oct 2015 Wedding-Hamilton, NJ

We can honestly say that Lou Costa of Top Notch DJ Entertainment was the best part of our event. Meeting Lou for the first time was like getting together with an old friend after a few years. He is an absolute gentleman, knowledgeable in his trade, and a dynamite entertainer. Lou went the extra mile with every aspect of our wedding reception, showing patience with various changes we wished to make to our itinerary and music selections and in helping us piece everything together. Lou helped bring our vision to life with ease. We would highly recommend Lou Costa of Top Notch DJ Entertainment to anyone, and hope to utilize his talented services again in the future. Lou–Thanks again!


Patti Bruno on behalf of her Daughter Kristen’s Sweet 16 Party; December 2015-Hamilton, NJ

Lou—Thank you so much! Just want to let you know how much we appreciate everything you did for us! Kristen’s Sweet 16 Party on Saturday night was phenomenal! You helped make the party what it was. We received so many compliments on the music. The older crowd to your right side appreciated that you worked in several songs they could dance to, while the younger crowd to your left loved your music and never minded when you threw some stuff in for us ‘old folks.’ Your blend for both age groups was just right. You nailed it!!! And thank you also for the Photo booth suggestion. That was a blast!!!!!! Between your DJ Services and the Photo booth-the party was a big success!! Additionally, the Up-lighting suggestion was a good one and I am glad we added that very special lighting touch to Kristen’s event! Lastly, I wanted to let you know that we received several phone calls/texts the day following the party telling us they had a great time. There were even some individuals that could not attend that made a point of calling us to let us know they heard from attendees who could not stop talking about the great time they had! Lou—Thank you so much again for a great job on Kristen’s Sweet 16!


Clint and Kristen Csizmadia; October 2014 Wedding-E Windsor, NJ

From the Bride & Groom:

“Lou was phenomenal!
He was very professional and made our wedding very special!
We would highly recommend him!.”

From the Mother of the Bride: Yolande

Just wanted to let you know what a great job you did at my daughter’s wedding, both with the music and as a master of ceremonies.
You kept the party going and played the music that we requested. It was truly a pleasure working with you.
The meetings prior to the event really helped them to focus on what kind of music they actually wanted and didn’t want.
Thank you so much for helping to make their day so special.”

From the Mother of the Groom: Linda

We wanted to personally thank you for the excellent entertainment you provided for our children’s wedding.
Everyone has told us they had a wonderful time and enjoyed all the music and then some.
I know it meant the world to Clint and Kristen. We all felt so comfortable with you and your professionalism shown through in every way imaginable.
I will definitely recommend you to anyone who’s looking for a fantastic DJ, which you are.
In the meantime, thanks again for helping make that day so very special.”


Matt and Cara Gilligo; May 2014 Wedding-Freehold, NJ

Lou Costa is an extraordinarily talented DJ, with a kindness to match.  My wife and I truly feel blessed for selecting such wonderful vendors for every aspect of our wedding.  Despite everybody being so helpful and talented, Lou stood out from the bunch during the planning process.  That is due to Lou’s talent, efficiency, personable behavior, friendliness, flexibility, charisma, understanding, and a seemingly infinite amount of intelligence for the work that he does.  Lou offered his services at a very reasonable cost.  My wife and I would happily recommend Lou to all our family and friends.  We really felt taken care of during the stressful time it is planning a wedding.  Lou was and is just an absolute joy to work with!  Our family and friends are still buzzing about our wedding close to a month later because of Lou’s talent!  Thank you a million times over for making our wedding spectacular!


Dawn K for her daughter Julia’s Sweet 16 Party-Sept 2014-Hamilton, NJ


Everyone had a fantastic time and danced the night away!  Not one of the kids sat begging to wish the night would end.  In fact, they are still talking about the party. 

I myself have not danced like that in like twenty years and I too wished it never ended.  I danced so much that I could not walk the next day-LOL! 

I will highly recommend you.  Thank you for making my daughter’s party a success! 


Todd and Cherilyn; 2013 Wedding-Laurita Winery, New Egypt, NJ

Top Notch says it all!!! Lou did a fantastic job.

He was with us through the entire process.

Setting timely contact events and meetings to make sure everything was in order.

Lou was our Master of Ceremony at our wedding and we couldn’t be happier.

It was everything we asked for and more. Lou kept the mood light and enjoyable throughout the night.

I highly recommend Lou for his professionalism, outstanding ability and how in the end we felt like we had another friend at our wedding, not just an MC.

Thank you!!!


Robin & Thomas Burket; 2012 Wedding in Freehold, NJ

Lou, from day 1 you have been nothing but the BEST… The best to work with, the best to talk to, your just the best at what you do and we were so thankful to of found you when we did.

The DJ industry has changed so much; these other companies have forgotten what is most important when it comes to wedding entertainment but not you.

You helped us with suggestions in all area’s we were undecided in and worked with us when we had last minute changes J

You are a true professional & we appreciate everything you did to help make our wedding day so special.

The CD you gave us at the end was extra special because you were able to capture all of our key songs and that meant a lot to us because that showed us how much you cared and how in tune you were with us & our day.

YOU ROCK Lou & we would highly recommend Top Notch DJ Entertainment for any event!  


Bridget & Chris Radice; 2012 Wedding @ Mercer Oaks in West Windsor, NJ

Top Notch DJ Entertainment was awesome!!

Lou made our wedding so amazing! We had a blast! 

He met with us several times to go over everything every detail. 

My husband is a musician, so he was a little picky and Lou had everything perfect! 

He was so organized.  He was very well dressed for the occasion and very professional. 

My guests danced the night away and so did I.  I loved the way he interacted with everyone. 

My guests keep saying how amazing our DJ was.  Thank you Lou so much for making our day so special!! 

Bridget and Chris


The Lobman Family; 2012-Sweet Sixteen Party for Daughter Natalie-Toms River, NJ   

Top Notch DJ Entertainment is definitely highly recommended by our family.  Excellent music, MC was right on the money and very professional.  Our daughter and her friends have not stopped talking about our party. 

Even the parents have stopped me and said their children had the best time. 

Working with Top Notch was both professional and “family” friendly!  Lou has the personality to keep the young and the “older” well entertained throughout the entire evening.

 I don’t think the kids sat down once. 

They were out there the entire night!  That, is a big challenge, for any DJ company, and Top Notch can do it!  No questions were unanswered and working with Lou was a joy. 

We would and will use Top Notch again and again and will be spreading the word to all of our friends and family! 

Thank you Lou for making our Natalie’s evening special!

A friend of ours showed us some post event footage at our reception and we could really see that everyone was really having fun. You got everyone on the dance floor, just like you said you would! Perfect mix of fast and slow songs, too.
Great job with the announcing, and with keeping the festivities moving forward throughout the night.
Thanks again for your services, and especially for the pre-event time you devoted to helping us plan out our wedding reception in the months leading up to our wedding.”
