I'm Marnie Grumbach

fractional marketing executive | communications strategist | brand problem solver | MBA

When a fraction delivers

(a lot) more.

"A versatile,

well-rounded marketer"

I am a senior-level marketing and communications professional who fully integrates with your organization. As a fractional marketing partner, I bring my 20+ years in the field to help build your marketing and communications strategy, oversee your team and collaborate with other partners – at a fraction of a full-time CMO salary. 


My depth of experience is in legal marketing, banking and finance, professional services and healthcare. Through agency partnerships, I have nurtured the brands of clients in A/E/C, non-profits, telecommunications, accounting, education and trade associations.

Senior-level strategy and leadership at a fraction of the cost.

You may not be ready for a full-time in-house marketing executive, but your brand shouldn’t suffer. I partner with clients as a fractional marketing or communications leader or fill in on an interim basis. As a member of your team, I am comfortable working closely with senior leadership, boards and committees, in-house teams and established vendors. 

Is this the same as hiring a marketing consultant? The difference is in the nature of the partnership. By design, it’s a longer-term engagement as compared to consulting. Clients benefit from my full integration with your internal organization. The length of the engagement affords us the time and intention to build, launch and reflect on a meaningful marketing or communications program. Your team has direct access to me, unlike many consultant or agency models, either hybrid or fully remote. 

Clients + Collaborations

I have worn many hats as a fractional partner, ranging from a marketing and PR executive for a bank’s wealth advisory division, a communications strategist for a national education non-profit and a designated marketer for a global law firm that needed go-to-market strategy and oversight for rapidly growing practice groups.
