About LA’s Top Acting Coach

29 Years of Coaching Actors to Success!

Diane Christiansen has been voted THE BEST acting class for Kids & best acting class for Teens in Los Angeles 2 years in a row by the Backstage West Readers’ Choice Awards.

We put the actor first.

For Diane and Tess, there is no greater joy than seeing our students succeed as actors. This is why we are dedicated to each and every student having a profound, unique, and uplifting experience at our acting school. Whether you are brand new to acting or experienced, Diane and her instructors are committed to creating a safe and inspiring environment for all…from 3 years-old and up.


About our Studio

Our school, reputation, and list of student bookings has grown immensely since Diane held her very first acting class for adults in 1992.

We know what it’s like to be in your position. . . to be an actor just starting out or moving to L.A. from your home, being the parent to a young child who has a dream, being a kid, teen, and adult going to audition after audition waiting for your opportunity to show what you can do, the joy of a booking and the disappointment of rejection.

We know because we too have personally been there – with Diane moving to Los Angeles from out-of-state and Tess beginning her professional career at a young age.

Our family business is our life’s passion and every student, new or old, is apart of that family.

This may be a business, but we don’t want it to feel like it.

Our commitment to actors stretches far beyond collecting tuition, it always has.

We know what it’s like to be in your position. . . to be an actor just starting out or moving to L.A. from your home, being the parent to a young child who has a dream, being a kid, teen, and adult going to audition after audition waiting for your opportunity to show what you can do, the joy of a booking and the disappointment of rejection. We know because we too have personally been there – with Diane moving to Los Angeles from out-of-state to Tess beginning her professional career at a very young age. Our family business is our life’s passion and every student, new or old, is apart of that family.

We put the actor first.


If you don’t show up for practice, you can’t win the game.

We believe that there is no “end goal” when it comes to actors training. If an actor is not in a regular class, constantly growing and practicing their craft, it is going to be very difficult to show up to auditions and expect to book. Even the biggest names in the business still work with coaches! This is why all of our scene study classes are on-going. There is no start or end date. You can join any time as long as space is available or sign up for session after session consecutively.

If your goal is to book more television, including a series pilot, set up a plan of action that will add value to your skills in that market.

1.  Practice Acting skills need to be practiced every day ⇒ 15 minutes of practicing cold reading will keep you sharp. If your cold reading isn’t the best, practice for AN HOUR PER DAY until it becomes as effortless as breathing. In classes and private lessons, we give students different tips and techniques to help them with every aspect of preparation.

2.  ‘Break Down’ Scripts Dissect several new scenes every week in order to understand the rhythms of the speech, subtext, jokes, etc. Finding new and relevant sides online for practice is a piece of cake.

3.  Pace TV IS FAST – Speed up your speech patterns. It won’t help an Actor to practice their scenes at a SLOW pace because the shows are actually performed at a RAPID pace.

4.  Workshops & Showcasing If you aren’t taking workshops every chance you get, then you aren’t building your knowledge and information base within the industry. So much of what you learn is unique to a show, a network, a production company, or a producer/writer. The more knowledge you have, the more effective you are at using your skills. Plus – WORKSHOPS keep your cold reading skills sharp when you are under the practiced eye of a BUSY Coach. Check out our monthly casting director workshop for actors of all ages, HERE

5.  STAY BUSY Drop off your head shots/resumes and postcards at key casting offices so you are constantly reminding the industry of WHO YOU ARE! Mail out Postcards of your successes. Make sure you have a good reason to send a postcard… Such as a booking, a play, an airing, a new agent, a premiere, or some other relevant update that says I’M BUSY and WORKING and IN DEMAND! Postcards without a purpose are a waste of time & overlooked.

6. Do Your Research It is your job as an actor or parent of a young actor to research the Industry, agents, managers, casting directors, auditions, etc. There are many helpful websites with incredible articles, insider tips, help for parents, and much more. Also – ask questions. That’s something your coach is there for; to answer the specific questions that may arise.

That’s enough to think about for now…

See you in class! -Diane & Tess
