Who We Are

I’m Rob Petrin, the founder of Petrin Development Services. I have a decade of web marketing agency experience, alongside over two decades of experience building websites. It’s fair to say that I am certifiably obsessed with the web. I founded PDS in 2023 in order to better serve my clients.

Before focusing on web development, I served as a Social Studies and Special Education teacher in Central Massachusetts. When I’m not serving my clients, I’m learning new technologies and growing my own business. When I’m not doing that, I’m spending time with my wife, dog, and turtle.

Alongside myself, PDS consists of a team of skilled and experienced graphic designers, photographers, videographers, drone operators, and social media managers.

Our extended network of partners enhances our service offerings while maintaining our trusted project management skills. These partners bring specialized expertise and resources that complement our core competencies, allowing us to deliver comprehensive solutions, whatever your needs.

By seamlessly integrating additional services, we ensure a unified approach to project execution and exceed client expectations. Whatever your project, you’re in excellent hands when you’re working with Petrin Development Services.

We provided a fully-custom theme, and installed Google Analytics 4 and Google Tag Manager, providing realtime and historical insights into visitor data. We work on content strategy and search marketing on an ongoing basis.
