A 1,500-person national conference, run 2,000 miles from home.
NAADAC wanted their general sessions to look more produced — and their entire
membership was in the room to see it. They held the event in Seattle, far from our
St. Louis base: the gear was a three-day drive out, and the crew had to come from
everywhere. We flew in techs from LA, DC, and beyond and ran them on staggered shifts
so the team stayed sharp through every session. Essential AV handled all live production
and recording — delivering the event for 1,500 attendees, plus a library of
recordings NAADAC now uses for marketing.

“
I have worked with many audiovisual companies over the years, including some
of the largest providers in the conference industry, and Essential Audio
Visual, LLC is simply the best.
NAADAC has partnered with Essential Audio Visual for several years for our
national conference, and they consistently exceed expectations. Their technical
expertise is outstanding, but what truly sets them apart is their responsiveness,
professionalism, and personal commitment to our success.
In 2025, we launched our first-ever hybrid national conference, and Essential
Audio Visual was instrumental in making it a success. They listened to our goals,
helped us think through the challenges, and executed flawlessly. Their team
delivers a level of service and attention that is increasingly rare.
Even when venues require us to use in-house AV providers, Essential Audio Visual
remains our trusted partner and advocate. They have my highest recommendation.

importantly, we love working with you all.”

03 · The problem
The category sells equipment. Planners are buying certainty.
Ask a planner what went wrong at their last event and you rarely hear about
equipment. You hear about the vendor.
The vendor who was responsive during the sale and impossible to reach during
crunch week — whose “policies” appeared the moment the timeline got tight.
The quote that started at one number and ended at another, once setup, labor, and
power got added. The gear that wasn’t there, because the AV company didn’t
realize it was short until the morning of the event.
None of it is about the gear. It’s about whether the people behind it pick up
the phone, tell you the truth about cost, and make the room work when the lights
come up.
These aren’t anomalies. They’re the category. Every published competitor sells
the same vague capability list with the same gated quote form. So we built the
opposite.
04 · The promise
Three numbers we publish. None of our competitors do.
Across eight St. Louis and national AV competitors, no one posts a quote turnaround,
a callback window, or a same-day reply guarantee. We do all three, on the homepage,
in writing.
Same dayInquiry reply
You hear back today.
Not a chatbot. Not a calendar link from a sales-development queue. A reply from a person who can answer the question.
60Minute callback
During business hours, every time.
Phone answered in three rings. If we miss it, we call you back inside an hour. Same lead, every call.
48Hour written quote
Itemized. Locked for 30 days.
Written proposal within 48 hours of your discovery call. No “starting at.” No surprise re-pricing the week of the event.
Why publish it? Industry research shows AV integrators who deliver proposals inside
14 days have an 88% win rate — but only one in four actually hit that window.
We’re committing in public to a window 12 days tighter. If we miss it, you’ll know.
05 · The receipts
Credentials, as facts. Not adjectives.
We don’t say “industry-leading.” We say two CCMP certifications,
two CTS certifications, 100+ years combined experience, and a 6,000 sq ft
warehouse on Weldon Parkway.

Real Essential AV events — St. Louis metro & national.
The company is new. The people are not.
Essential AV became independent on January 1, 2026. The team that
stands behind it has been running St. Louis corporate, nonprofit,
medical, and training events for over a hundred combined years.
Bill Dethrow runs the company. He answers the phone, runs the discovery
call, writes the quote, and is in the room on event day. The same lead
tech you meet on the quote is the one on-site at load-in.
— Bill Dethrow, Founder
06 · How it works
Four steps. No surprises.
From inquiry to load-out, here’s exactly what happens and when.
01
Discovery call
30 minutes · same week
Walk us through your event. Date, venue, attendees, run-of-show, and the three moments where failure would be most visible. We ask about the program before we price the equipment.
02
Written quote
48 hours · locked 30 days
Itemized proposal. Setup days and show days separated. Crew named. Backup gear listed. No “starting at.” If your budget doesn’t fit, we’ll tell you in 24 hours instead of two weeks.
03
Tech check
Week of event
We confirm the gear loaded on the truck, the crew on the call sheet, and the room walkthrough. You hear from us before you ask.
04
Event day
Setup through strike
Same lead tech from quote through load-out. Backup tech on call. Backup gear on the truck. You’re in the room with us, not chasing us.
07 · What it costs
Most St. Louis AV companies won’t show you a number. Here’s ours.

scope that matches your room, and day count becomes a transparent add-on line,
not the headline.

Hotel and in-house providers carry a documented 20–40% markup over outside
vendors through venue revenue-sharing. Bring us your in-house quote and we’ll
give you a written side-by-side — and negotiate the venue’s AV team on
your behalf where contracts allow it.
Permanent installs (separate rate card)
Huddle roomfrom $5,000
Conference roomfrom $12,000
Boardroom / training roomfrom $25,000
Every install starts with a $1,500–$2,500 AV assessment — credited back

to it.

09 · Honest answers
The four questions every planner asks.
Answers Bill would give you on a call — in writing, so you can compare them to whatever your incumbent vendor said last time.
We’ve always used our current vendor. Why switch?
You don’t have to. We don’t ask you to displace anyone. We ask for the next event where your current vendor is at capacity, the timeline is tight, or you want a written backup quote on file. Reactivation, not replacement.
If we’re better on paper, the next one’s ours. If we’re not, no harm done.
We don’t have budget for premium AV.
We publish our floors, so you can plan before you ever call. Single-room general sessions start at $5,000; most 300–500-attendee programs land between $8,000 and $45,000, depending on production scope. Nonprofits, churches, and schools take 15% off.
If your budget is below that, we’ll tell you inside 24 hours instead of stringing you along for two weeks of meetings. The number isn’t the problem. The not-knowing is.
How do we know you’re better than the other quote we got?
Three things on paper:
One, a published response SLA — same-day reply, 60-minute callback, written quote in 48 hours. Two, two CCMP and two CTS certifications on the leadership team. Three, a 6,000 sq ft warehouse on Weldon Parkway you can tour before signing.
Read the quote. If it’s vague, it’s not us.
You only went independent in January. Why trust a new company?
The company is new. The people are not. The leadership team has 100+ combined years running St. Louis events — corporate, nonprofit, medical, and training — with the certifications and the warehouse to back it up.
What changed on January 1, 2026 is that we became independent. The continuity is the team.
