SERVICES

SERVICES

There are three ways for us to work together. On their own, or one after the other. Every project is one-to-one with me, from first conversation to final file.

Build It

Branding

A brand identity built on real strategy, not guesswork. We start with an in-depth discovery session, then I design an identity that feels like you at your best.

Launch It

Website

A website that looks the part and is easy for you to run. Built on Squarespace, set up for search, and handed over with a video walkthrough so you’re never stuck.

Keep it Working

Retainers

Your own in-house designer, without the hire. Each month we plan what’s coming, I design it, and everything you put out looks like you.

Meet the Founder

Creative Thinker - Mari Therese

I founded Studio Marbar on one belief: that a great brand isn't just something you see it's something you feel.

With over 20 years of experience, I work one-to-one with founders and growing businesses to uncover what makes them genuinely distinctive. Through deep discovery and strategic thinking, I act as a mirror helping you see your business clearly, define a confident identity and show up with purpose.

The Grace, Westport Estate

Luxury Hotel Visual Identity

Working closely with Legacy Communications and Westport Estate, I helped them define the overarching visual identity for the hotel. That meant a colour palette, typography, graphic devices, textures and photography mood.

Nancy’s Barn, Ballyliffin

Café Brand Refresh & Website

With their visual identity system feeling outdated and inconsistent across touch points, they needed a cohesive brand and website strategy that reflected their Donegal roots, coastal setting, and warm, welcoming personality without straying too far from what their loyal customers love.

Kind words from my clients.

"She is very creative and considered"

Working with Mari on the Buncrana Town Team Action Plan was a great experience. She is very creative, considered, extremely responsive, and attentive to detail. The finished product was really impressive and the Buncrana Town Team happily recommends Studio Marbar.

Anne Marie McLaughlin, Buncrana Town Team

"Mari’s discovery sessions are an absolute necessity"

If you are looking to see your business and your own potential through an entirely new lens, Mari's discovery sessions are an absolute necessity.

Jude Torley, Shabra Group CEO

"She pushed us…"

She pushed us to move beyond the day-to-day operational mindset and helped us define a high-level identity that feels both powerful and true to our values.

“We are so proud of it!”

We couldn’t be happier with the finished result. A huge thank you for your incredible patience, creativity, professionalism, and attention to detail. The branding and website are everything we hoped for and more, we are so proud of it!

Kieran Doherty, Nancy’s Barn

How it all Works

We start with your story.

STAGE 01 - DISCOVERY

It all begins with a free 30-minute call, then an in-depth discovery session where we dig into your business, your customers and what makes you different. You’ll come away seeing your business more clearly, before a single thing is designed.

Your brand and website take shape.

STAGE 02 - DESIGN & BUILD

I turn what we uncovered into a brand identity, a website, or both. You’ll see the direction, give feedback in clear rounds, and nothing is signed off until it feels right.

You go live, and stay looking your best.

STAGE 03 - LAUNCH & ONGOING SUPPORT

You get every file, your brand guidelines and a video walkthrough of your website. Then, if you’d like, I stay on as your designer with a monthly retainer, so everything you put out keeps looking like you.
