Digital Strategy Review from Meara Cummings
We've had a fantastic experience working with the New Target team so far in our rebranding project. This is the first formal rebrand in the organizations history, so it was critical to get it right. From day one, Hannah (account manager) and Rachel (lead designer) brought a thoughtful, collaborative, and incredibly well-structured approach to the process.They have worked seamlessly with our rebrand committee, balancing creative exploration with clear communication and deadlines that kept us moving forward. After this strategic and thoughtful approach has resulted in a modern new logo and comprehensive brand guidelines that truly capture the spirit of the association.We are so grateful for their partnership and would highly recommend New Target to any organization looking for a creative / digital partner!

Digital Strategy Review from Anisha Carter
Rachel and Hannah were incredible! They were attentive, inclusive, and willing to adjust based on my team's feedback. Hannah was very proactive, and we didn't have to "ask" for this anything. It was just already available. She helped us craft a plan/roadmap and delivered against it as expected and often times above and beyond. As far as design, Rachel helped bring our ideas to life. She also leaned into the areas that we demonstrated more energy around. She pulled inspiration from a variety of areas to help us decide on a name and develop our 'branding starter-kit' including logo, style guide, and initial image assets. Both of them contributed in the design process and helped us focus which made our iterations more efficient.

Digital Marketing Review from Mike Suser
I have worked with New Target (and its predecessor) for twenty years. My business would not have been successful without their excellent assistance. They have redeveloped my website and kept it running smoothly. They have done a wonderful job with their digital marketing and work closely with me to create new directions for advertising.

What impressed me most about this company was how genuinely invested they were in bringing our vision to life. They truly cared about getting it right and shared in the excitement every step of the way. Their passion for what they do is obvious, and it made the whole process not just productive, but fun. It felt like they were part of our team, not just a vendor.

Black Flag carried us from concept to production on a very complex website with multiple interest holders. Designing a website for the California Department of Education means that we serve a varied user base and must adhere to the highest accessibility standards. Black Flag took input from internal teams, educators, and other interested parties that would be accessing and using the site. They adapted their designs to meet the needs of various types of users, coming up with not only attractive design elements, but created code that added automation to eliminate some of the manual updates. Black Flag provided us with a high-quality product and were so much fun to work with along the way. A helpful tip: save some of your funding for ongoing maintenance because once you start working with them, you won’t want to stop!

The team a Black Flag Creative interviewed our group at key milestones throughout the web design process to thoroughly understand our industry and the goals we want to achieve with our new website. I've been through a number of website updates with just as many web designers and Black Flag communicated with us in terms the layperson can understand, making it easy for us to provide content (both media and text) that would allow them to develop a website with the look and feel we wanted. They are just the right balance of website knowhow and flexibility in their thinking.

Great experience and highly recommend. The website that they made for me (a dentist) is extremely chic and I've gotten a lot of compliments on it from friends, family, and patients. I didn't have to tell them anything about the design, they nailed it from the start, which shows they have experience and a keen eye for website esthetics. They were easy to work with too. So any time I wanted to change any pictures or formatting, they had no problem doing it and they did it very quickly. It's clear they have a lot of experience designing websites for the healthcare field. Highly recommend Rizer!

I was referred to Rizer by a trusted neighbor. We had been with another SEO company for many years, believing they had our best interests at heart. However, they kept increasing their fees even as our leads and rankings steadily declined.In just two months of working with Barahm and the team at Rizer, we've already noticed a significant increase in traffic and quality leads for our business. They thoroughly cleaned up and optimized our website and are always available to answer any questions we have.If you're looking for a company that genuinely cares about its clients, I highly recommend Rizer!

His process was easy and it helped create clarity and focus for my business and marketing. I also have a repeatable process for content creation and to continuously drive traffic to my site. Most importantly, Johnny was willing to work within my budget. I have already started seeing improvements and will continue to work with him in the future. If you are looking for a web developer that can do it all, I highly recommend Johnny and the Phoenix Afterglow team.
