Over the past few years, we have been working with WebFX on various ongoing projects surrounding our websites.

Emily Pearce Director of Communications at Expereo

Public Relations Review from Emily Pearce
This agency was only used for a short period. A pleasant and responsive team but not quite as strong on strategy, C-Suite engagement/interviewing or ensuring our organisation provided enough information to achieve the best results.

Christine Quarte's Review Sourced from Google
I had the pleasure of partnering with Media FRENZY to help with brand repositioning and strategic work, and the experience was phenomenal. They were truly amazing partners—strategic, creative, and always willing to push us when needed. Their in-depth process ensured every detail was addressed, and they remained open to discussions, feedback, and exploring new concepts with us.Media FRENZY consistently brought fresh ideas to the table, showcasing their ability to think outside the box while keeping our goals at the forefront. Their collaborative approach and dedication made them excellent partners throughout the journey. Sarah, Dave and team were professional, collaborative and quite frankly, a FUN team to partner with. If you're looking for a marketing agency that combines strategy with creativity and genuinely listens to your needs, I absolutely recommend Media FRENZY.

Fantastic company. They do PR and marketing the right way and care deeply about clients. If you’re in need of positive coverage and results, I’d recommend MFG to any organization looking for a true partner.
