Passionate about what I do, and I know my stuff—inside and out. My work isn’t just a job. It’s my chosen career because I love what I do. That’s why I'm always looking to learn and grow in my expertise. It’s fun for me, and it results in a better partnership with my clients. 2. Work towards client successes. I want my clients to be happy at the end of the project and achieve their goals. When a project runs smoothly and the clients are achieving their goals, I'm happy too. Simply put, my goal for every project is to make You succeed. 3. Set expectations clearly from the beginning. I don’t think it’s impressive to toss out lots of technical terms and trendy vocabulary. That can be downright confusing. I believe in transparency and straightforward planning sessions with concrete objectives and clear expectations. 4. Get to the root of a problem and solve it. When the occasional roadblock appears, I assess the situation and develop strategic solutions. No problem is too big or small. See rule #2. 5. Approach clients with honesty and confidence. I hold myself accountable to my clients. I present precise, honest assessments throughout the project. Looks good, does good I believe that as creatives I have a moral duty to design responsibly, whether it is the selection of materials, the body of work I undertake or perhaps more importantly, the message and behavior changes that my work can achieve. Effective design is transformative, it can change patterns of behavior, interaction and the business. I see this in my work for small and medium companies and state organizations. Being creative is challenging, every project is different and requires careful consideration. Our lives are spent inventing and evolving with a pressure of time.
