We’ve had the pleasure of partnering with a variety of creative businesses. We build relationships as we build design. And we help our clients to find and grow their visual voice through carefully considered design solutions - all to give them the credit they deserve. 

Here’s what they have to say...

Sonja has been working as CIBHS's graphic designer for over five years creating all our conference programs, signs, and event collateral. The turnaround time is fast. Sonja takes a lot of pride in her work and it shows. Flexible, responsible, very calm, team player, gets the job done.

I have had the pleasure of working with Sonja for over ten years and enthusiastically recommend her services. Design&Effect is attentive, prompt, and creative. She responds immediately to requests and always provides a quick turnaround. Her work is not only imaginative, but she is efficient, accurate and mindful of budget constraints.

I totally trust Sonja. When I leave for vacation or illness, she is the person I trust with my clients. I can trust her to know how to not only take care of them but also to exceed their expectations, which is our shared vision for customer service. Sonja is humble, kind, and unassuming. She is a person who knows how to keep her agreements, foster a true environment of teamwork, and get optimal results.

I've worked with Sonja for over five years on a variety of projects. With all these different projects, she is always prompt and on deadline, knowledgeable about design elements and marketing, and gives valuable feedback and ideas. Sonja is incredibly professional and a pleasure to work with.

We had a vision of what we wanted for our new website design but lacked the skills to bring it all together. Working with Sonja was a godsend. She grasped our ideas and built the design into a fully fleshed site. Once the new website was launched, we were able to double the subscribers to our email list and activity on the site has gone up markedly.
