The bridge between operations and marketing

Most small organizations have the same gap: marketing that isn’t connected to how the business runs, and technology nobody has time to own. We work across both. Brand positioning and SEO strategy sit next to workflow optimization, CRM implementation and digital infrastructure oversight.

The result is executive-level guidance and hands-on execution without the cost of a full-time leadership hire. We stay for the long run: several clients have worked with us for five years and counting.

How we work

Strategy before trends

A new website isn’t always the fix, and content alone won’t cut through. We start from your goals, then choose the work.

We explain as we go

Clients consistently tell us they learned how their own systems work. Understanding your tools makes you less dependent on anyone, including us.

Honest recommendations

We act in your best interest and only suggest what we sincerely believe will make a meaningful difference. Sometimes that means telling you what not to spend money on.

Built to scale

Good systems grow with you. Our work at Lydia Sierra Consulting supported a team that grew from a handful of employees to a staff of 20.

Where we work

Based in Brooklyn, New York, and working remotely with clients in New York, Rhode Island, Puerto Rico and California. Service in English and Spanish.

In their words

  • JR has been my go-to web developer for years, and I couldn’t recommend him enough. He is incredibly knowledgeable, dependable, and always stays ahead of the game when it comes to technology, updates, and finding solutions. He doesn’t just build websites or help with marketing; he takes the time to understand your needs and makes sure your vision aligns with your goals.

  • JR has a deep intuitive understanding of his clients needs. He is able to quickly go from an introductory conversation to a personalized plan optimized that solves problems that his clients didn’t realize they had. Educating his clients on the nuances of the business, combined with his transparency make him a pleasure to work with and an asset to any team.

  • I used JR to help me with some design on my WordPress site, deal with the tech aspects behind the scenes and speed it up. He was very proactive, helpful, and effective. Highly recommend!
