Boutique Digital Marketing Agency

collystring has supported Toothio across SEO, paid search, and paid social, not just as an execution partner but as an advisory one. They help us think through strategy and channel mix, then run the work day to day. At this point they function less like an outside vendor and more like an extension of our own team.

The results speak clearly. Within the first twelve months of working with and optimizing alongside collystring, we cut our customer acquisition cost in half. That kind of improvement doesn’t come from a single tactic. It came from sustained testing, disciplined budget management, and a willingness to keep refining what was already working.

On the operational side, they are consistently organized, prepared, and responsive. Every conversation is grounded in data rather than opinion, and they come to meetings with a point of view and the numbers to back it up. They also treat our budget the way they’d treat their own, recommending against spend when it isn’t warranted and reallocating quickly when something isn’t performing. The quality of the work is high and the reporting is transparent.

What I value most is the candor. When something isn’t working, we say so plainly on both sides, and then we solve it together. That collaborative, no-ego dynamic is rare in agency relationships and it’s the reason this partnership has held up.

I would recommend collystring without hesitation to any company looking for a paid media and SEO partner who is strategic, accountable, and genuinely invested in the outcome.

collystring has been an invaluable partner to Redirect Health, providing exceptional support in media buying, digital marketing channel testing and enhancement, ad positioning, landing page development and optimization, and critical campaign tracking. Their strategic oversight has ensured our campaigns are not only effectively placed but continuously optimized for peak performance.

collystring truly feels like an extension of our team. From performance marketing to SEO and content creation, the team has been incredibly helpful and agile throughout our four-year partnership. The collystring team helped us implement ClickID to better track customer journeys and crafted a series of detailed industry whitepapers—one of our best-performing B2B lead gen campaigns to date. 



Not only are they experts in their field, but the team is full of genuine, good people who are really easy and fun to work with.

Partnering with collystring has been one of the best decisions I have made for my medical practice. Their team truly understands the unique challenges and compliance considerations of marketing in the medical field, and they’ve delivered exceptional results every step of the way. 

From HIPAA-compliant digital ad strategies to beautifully designed patient-focused content, their work has significantly increased our online visibility, new patient inquiries, and reputation in the community. Within just a few months, we saw a measurable uptick in website traffic, Google rankings, and appointment requests. What I appreciate most is their professionalism, responsiveness, and deep knowledge of the healthcare industry. 

They don’t offer cookie-cutter solutions—they created a custom strategy tailored to our specialty, patient demographics, and goals. The ongoing communication and transparent reporting make it easy to understand what’s working and why.

If you’re a healthcare provider looking for a digital marketing partner who understands both the clinical and business side of medicine, I highly recommend collystring.  They are more than a vendor—they’re a trusted extension of our team.
