Running a small business is like driving a sports car. We’re accelerating into the twists and turns in the road. We can stop and pivot when our clients need us to. We’re agile, responsive, and confident. Sure, there’s comfort in riding in a big, cushy bus. But on winding, treacherous roads, we’ll take the smaller, sporty car any day. It’s a big deal to be small.

Fun times celebrating our Avyance 5-year anniversary at our company picnic last week! We basked in the sun, waded in the Shenandoah River, and enjoyed each other’s company. Love this team!

Trash, trash, go away, come again some other… WAIT, no, don’t. The Avyance team joined again with Langley High School seniors for an Adopt-A-Highway road clean up. Our team spent 25 person-hours scouring the roads, yielding over 15 large bags or trash. Mind you, our last clean-up of the same roads was 8 months ago. That’s a lot of new trash! We’ll keep doing our part to keep Northern Virginia beautiful, but gosh, wouldn’t it be great if people stopped littering? Many thanks to the Langley seniors who helped!

Failure - such a harsh word. Let’s try to use “lesson” instead. Success is built on a series of lessons, some that step us forward, some back. Stretching and growing ourselves (and our businesses) is the only way to success. And if we didn’t have some painful lessons along the way, we’d never get to the goal. Our Avyance hat is off to NIKE, for their messaging about growth, and their great reframing of the word failure. May we all see painful lessons as building blocks to better.

The “now” of work. We look back at 2019 and wonder how we balanced it all (suits and stilettos for 10+ hour days—anyone else?). Now work is woven into life—it’s a zoom call in slippers with a finger hovering over mute to silence the barking dogs. Now work/life balance means un-weaving work from life, being present in each discretely, and not always having one foot in each world. Here’s to everyone who has found the right balance and is thriving, and to everyone else, the struggle is real, and Team Avyance feels ‘ya.

Avyance is now 8(a) certified!
We are proud to share the news that Avyance was accepted into the US Small Business Administration (SBA) 8(a) business development program. Of 24 million US-based small businesses, fewer than 9,000 have 8(a) certification. This 9-year program allows participants to compete for federal sole-source contracts with up to $4 million ceiling for goods and services. Avyance is thrilled to expand our relationships within the federal government to help our clients secure direct access to the management consulting support they need.

It’s a dog’s life… or so they say. Meet Malou Jeppesen, who’s living her best life while visiting Avyance headquarters. Avyance consultant Warren Sloop taught Malou a few client service best practices: no barking at clients, commit to continuous learning, and never, ever eat deliverables.

EUREKA! Avyance has found that magic formula for a fun Zoom happy hour. Aviation trivia + fun facts about the team = a lot of laughter (and some surprise!). We learned that Andrea is a trivia ringer, Trish “Rocks” the elevator, and Brad (aka Matt Damon) is a Fuji-climber. And Jessica, thanks for NOT going into a legal career, you’re an excellent consultant. Big kudos to the host with the most…Warren. Thanks for the happy, happy hour!

A benefit of being a small business is that your team really does feel like family. We’re delighted to congratulate Lt. Commander Dennis Harbin, judge advocate, for his recognition with the prestigious Richard R. Baxter Military Prize. Congrats to Dennis, Jessica, and the whole Harbin family! It’s an honor to have you as friends and “family.”
Lt. Cmdr. Dennis Harbin – a judge advocate currently serving as a joint legal observer and trainer for the Chairman of the Joint Chiefs of Staff – was awarded the 2021 Richard R. Baxter Military Prize by the American Society of International Law (ASIL) Lieber Society on the Law of Armed Conflict. His writing topic was “Targeting Submarine Cables.” Read more about his accomplishment! ⚓
