"Become a Host changed my life! And I know that is a huge statement, but I mean it wholeheartedly. After hosting at the young age of 10, I took a long break before deciding that it was time to get back in the business. I did so, by picking up the phone, calling Become a Host and taking Marki's weekend boot camp. Immediately attracted to her advice and lessons, I knew that if I was lucky enough to place into one of her classes, I would embrace the opportunity. Fortunately, I did, because I learned from the very BEST in this business. While taking class, Become a Host produced my first reel. Cassandra and the whole gang nailed it! Needless to say, step by step, I honed in on the craft. I then did the Hosting Showcase which catapulted my career! I now work for Fuel TV and G4 TV!! Marki's school really works! I would never be where I am today with out Marki Costello and Become a Host! Here is a big THANK YOU to the whole gang!!! XO!" –Nicole Daboub

"I look forward to continue working with Marki and team... I attended the hosting bootcamp a few months ago... and in addition to doing more TV promos/interviews with The CW (DC50) as their "Dating Diva", I was just called to audition this Monday as a dating expert for a new dating makeover TV series. Marki was right.. I do have a killer brand, and continuing to work with you will help my dream of becoming a dating/relationship TV Host a reality!  THANKS SO MUCH!  I have so much more confidence in my abilities having attended the bootcamp!" -JJ

"Marki, I hope all is well with you.  I wanted to say thanks so much for everything you've done for me.  I hope to return to classes soon. I wanted to show you the web series that I booked because of you! showme.tv." -Chad Biagini

"I just signed a long term development and hosting deal with DIY/HGTV and will be shooting my first show Extra Yardage as host for DIY at the end of this month. Thanks to Marki for her help, harsh honesty and a great bootcamp program." -Billy Derian

“Marki Costello’s BecomeAHost Bootcamp put me on the fast track to my Hosting career. Not only does she teach you the general Do’s & Don’ts but she delves in to personal branding and how to stand out in an industry full of teleprompter savvy failed Hollywood actors.” –Lisa Canter

“Marki Costello’s blatant honesty is humbling and genius. She knocks you off your pedestal immediately and puts you in the right frame of mind to sincerely connect with your audience and Become A KICK ASS Host!” –Debbie Lisps

“BECOMEAHOST weekend is like an adulthood Summer Camp experience. Getting to spend time with and learn from people with similar passions and interests. Marki Costello is the ultimate Camp Counselor too as she doesn’t put up with any Bull Shit.” –Jenna London

“Marki taught me that there are 50,000 other people out there that want to do what I want to do and then immediately helped me to determine what would make me stand out at a general and at an audition.” –Melinda Forbes

“I have been struggling in Los Angeles for years. It wasn’t until I attended BecomeAHost and the Academy that I was put in front of some of Hollywood’s Hosting elite. From celebrities like Jason Kennedy and Giuliana Rancic to Executives and Casting Directors from MTV, Style, E!, even the Discovery Channel! This has been the first time in a long time that I have felt like my career is on the right path.” –Tina Fitzpatrick

“I can’t tell you what a breath of fresh air Marki Costello is. Although considered a tough cookie, all of her feedback is sincere and comes from years of being a significant figure in the Hosting… and frankly, The Entertainment World. BECOMEAHOST Bootcamp is an experience that you can not pass up if you want to be taken seriously in this arena.” –Sam Wynn

“Marki’s ‘Take No Prisoners’ approach is intimidating as much as it is an adrenaline rush. Her Bootcamp, BecomeAHost, is such an emotional experience. You leave feeling pumped for your career and ready to take on the world!” –Michelle Carr

"I flew out from Denver, Colorado to attend the Hosting Bootcamp in May 2009, it was the last class Marki conducted before going on leave. It was a big class and over those 2 days I learned SO  MUCH about hosting and the concept of branding. Shortly after the bootcamp, I flew back to LA to get my demo reel done. Both Kyle and Cassandra were great to work with and they did a fantastic job on my reel which shows my brand which again  "branding" is what Marki drove home that weekend. Post demo reel, I became a subscriber of the "becomeahost website" and I recently flew back to LA May 2010 for a private session with Matt Gallant.

Well, I must confess that the demo that I got done by the becomeahost staff back in June 2009,  helped me to book my first professional hosting gig. In December 2009, I was selected to host the Kingdomwood Film Festival Showcase which aired on national television, the ColoursTV Cable Network in May 2010. Not only did I get to host the festival, I also had an opportunity to write the scripts for each of the movie reviews. It was a blast. I am hoping that this opportunity will open doors for other opportunities down the road. I would love to host a program on the tennis channel. I am a huge fan of the network and love playing the game of tennis. Thanks Marki for your honesty and for conducting such a great program. When I move to LA, I hope to attend more of your classes so I can fine tune the craft of hosting." –Michael Cousins

"Marki Costello is someone you HAVE to meet if you want to become a host. Last year, I was curious about hosting and found her website.  I decided to take the Hosting Bootcamp. At first, her teaching style may be a bit shocking, but after you get used to it, you keep coming back for more. Then I took her weekly classes, and participated in the hosting showcase. She holds your hand through the process and tells you exactly what you need to do.  She is blunt, and will not hold back.  As she puts it,"If you can't handle me, you will never make it in this industry!" and as always, SHE IS RIGHT!  You have to do the work and want it. I am now appearing on various shows as The Hollywood Diet expert!  I just got back from Philly doing a talk show segment, and now other shows are contacting me. I have used everything Marki taught me to get to this point. There is no one like her, and she is truly the Queen of Hosting!  Becomeahost classes are the best investment I have made in my hosting career.  Thanks Marki, I will make you proud!" –Lisa De Fazio, MS RD
