What Makes Us Different

Marketing is only part of the picture.

Clients usually know what they want. What is harder to know — from inside a business — is everything the request touches.

A client says: "change our phone number." A vendor changes the website. We change the website — then check Google Business, social media, advertising accounts, directories, email templates, booking platforms, 360GrandLake where it applies, and everywhere else that number still exists.

That habit applies to everything we do. We deliver what you asked for, completely — then tell you plainly what else is connected to it, what deserves attention next, and what can wait.

Marketing, advertising, communications, public relations, brand, creative, websites, search, content, photography, videography, digital, automation, events, sponsorships and business consulting all live under one roof here. That is what lets us see how the pieces connect.

Our Process

How the work actually happens.

We look at the whole picture, tell you what we see, sequence the work, and do it.

01

Understand

We start with what you want changed or promoted — then look at everything connected to it.

02

Identify

We flag what else should be updated, corrected or connected, and what genuinely doesn't need attention.

03

Prioritize

We sequence the work by impact and deadline instead of handing over a wish list.

04

Execute

We do the work — writing, designing, building, publishing, posting, placing and coordinating.

05

Maintain

We keep it current. Marketing decays quietly, so someone has to be responsible for noticing.

How We Work

One project — or your entire marketing department.

No giant agency minimums. No one-size-fits-all packages. National-caliber work without requiring a national-agency-sized minimum engagement.

  • A few hours of professional help
  • A defined project or campaign
  • A monthly marketing budget
  • Ongoing marketing management
  • A complete outsourced marketing department

Tell us what you're trying to accomplish and what you have to work with. We'll tell you honestly what it takes, what can wait, and where to start.

About GSM

From a kitchen table in Northeast Oklahoma to a national agency.

Michelle Robertson founded Grand Splash Marketing in 2009 after working in printing and radio, where she watched local businesses struggle to navigate a digital shift nobody nearby specialized in. She started the agency at her kitchen table.

Today GSM is a full-service marketing, communications, creative and consulting agency serving businesses and organizations nationally — still based at Grand Lake, still led by its founder.
