At 57, is there any hope?

So, I co-founded and ran a graphic design agency in the UK for 25 years and just relocated back to the US around 6 months ago.

I have started looking for potential roles and am a bit stuck. I thought about working for larger companies, possibly in project or product management. I have a strong background in project management and marketing as per my latest resume.

My education is lacking on the college front other than some business admin and accounting classes taken decades ago.

I have been firing off resumes like no tomorrow that has had little response. My summary is as follows:

PROFESSIONAL SUMMARY

Highly organized and detail-oriented Project Coordinator and Marketing Project Manager with 20+ years of experience managing cross-functional projects, creating project briefs, streamlining workflows, and ensuring on-time delivery of marketing and creative initiatives. Advanced Asana proficiency with a strong background in process improvement, task prioritization, and project execution within agency and client environments. Proven ability to collaborate across global teams, facilitate communication, and enhance operational efficiency.
