What it’s like to work with me

From project managers, marketers and designers I’ve teamed up with.

Clients would often say ‘Karen can do anything.’

I cannot recommend Karen enough! Not only is she amazing at what she does, but is a wonderful person to work with. Karen approaches challenges head-on and has the most amazing problem-solving mindset.

Everything she delivered to me was done beautifully and with so much attention to detail. I could confidently assign her anything knowing that it would get done. Hope I get the chance to work with her again!

Ashley Lawson Sr. Project Manager @ Origin 63

Working with Karen has been an absolute joy.

She’s incredibly creative and innovative, always responsive, and consistently brings thoughtful ideas to the table.

As a team of one, knowing I can rely on her support has eased so much anxiety and given me real confidence as our company and brand go through change.

Rachel Miller Senior Communications Manager @ CMTC

Karen would be an asset to any team.

Working with Karen has been one of the easiest things I’ve ever done in my career. I could always trust that when I gave her a web design it was going to be executed with precision and care.

Agency life by nature is hectic, but with her calming demeanor and legitimately positive attitude I felt like we could get through whatever emergency was thrown at us.

Mandi Chapman SEO + GEO Strategist

I believe she would be an asset in any work environment.

Karen is not only a hard-working and intelligent person, but she is also a creative, easy-going and honest person.

I have no doubt that Karen would excel in whatever endeavor she sets her mind to.
