Beck is charming as Andy, eliciting all of his naturally nervous qualities in actions as sweeping as confronting his idol or as tiny as donning or removing his jacket; he really seems to treat it as though he believes it doesn’t want it to touch him, which adds a sad pathos to a man you can’t help but like.”
— Talkin' Broadway for "Animals Out of Paper"
It is difficult to overpraise the cast...At the curtain call, just for a second, I looked at Beck and thought, who is this guy? He’d created such a completely other physical persona for Andy that I almost didn’t know him.

David Beck shines as the uncomprehendingly self-involved Matt...Acted impeccably under the nuanced direction of Craig Baldwin, the show is, in a word, terrific.

...If all that spells nerd, it’s true, but Beck manages to combine bashful gaucherie and yearning and self-knowledge without ever seeming week, effeminate, or just foolish. It’s a beautifully modulated performance.

[An] emphatic and nuanced performance from David Beck.

Well acted by David Beck

One of the strongest elements of this production is its stellar cast...David Beck as Andy works for every ounce of sympathy and endearment. He is very grounding throughout the play...when you have a cast of talented actors and a smart script, all you really need is an audience. I recommend that you provide that element to this production. It’s well worth it.

The two actors [David Beck and Mary Joy] fully inhabit their characters and share a strong chemistry that makes believable their propensity to confide intimate details of their lives so readily.
— TheaterMania for "On a Bench"
Both actors [David Beck and Mary Joy] are great and play off each other wonderfully.
— Broadwayworld for "On a Bench"
For Pete’s Sake is an intelligent, inspiring, and important piece of theater. I left this show truly excited by what it has to offer—and I immediately began to spread the word.

The use of two opposing voices in [Joe’s] head, brought to life wonderfully by actors Alfredo Diaz and David Beck, serves as the perfect device to illustrate his inner struggle. The three actors work off each other beautifully.

It’s hard not to be engrossed by the couple’s ill-fated predicament and especially by the strong performances from Murphy and the charming Beck, both of whom convey the angst of love in a time of war with great sincerity.
— Show Business Weekly for "Never in My Lifetime"
The most appealing cast member is David Beck as the younger Paul, who wins the audience over with his boyish charm. He subtly navigates through each moment of the relationship, as he fights for his relationship with James to work.

A touching David Beck as Thesus’ son, Hippolytus.

The ‘Piano Teacher’ is an artistic gem...

David Beck does an amazing transformation as this menacing, musically talented young man with mood swings, within seconds, from moments of gentleness to an anger of frightening fury.
— Hardwick Gazette, Vermont for "The Piano Teacher"
Equally adept was Beck’s performance, a tormented Hamlet coping with his demons and mortality, then striking out in an angry diatribe against Ophelia...

The dramatic range from Hamlet’s passion to Demetrius’ absurdity exacted a demanding performance by Beck.

I’m just gonna get right on out with it—-one of the stars of this show looks like a young Patrick Wilson.

That should sells tickets on its own. I mean. He’s handsome. And so alarmingly Wilsonesque that you notice it the minute he steps on the stage. You can’t stop noticing it.
— The Craptacular for "The More Loving One"
As a companion who may be the poet’s younger brother or an emissary from beyond the grave, David Beck is memorable.
— The Irish Echo for "Walking the Road"
Beck, small of stature and with a child-like countenance, also deftly alternates among a number of sub-characters with falsetto voice or lordly demeanor or a commanding officer’s orders to charge into battle. Noonan and Beck more than deserved the ovation they received.
