Randy Tuminello, MBA PMP CPTD

CEO and Principal Consultant


For over 25 years, Randy has honed his expertise in business and marketing strategy, client relations training, client perception studies and executive coaching. As a Certified Project Management Professional (PMP), he offers a dual background in client and project management.


Randy speaks frequently at national and regional professional association meetings and for the past 12 years has served on the faculty of the American Council of Engineering Companies (ACEC). Currently, he teaches a master’s class on ‘Strategic Marketing’ in their Core Competencies for Principals program. Widely published, Randy has written over 100 articles on client relations, leadership and business development.

My first introduction to Randy was through a series of articles Randy authored for the Daily Journal of Commerce in Seattle. Those articles on client relations struck a chord with me and led to Randy consulting with our company on sales strategies, developing highly functional client relations and facilitating strategic planning sessions for our leadership team. I highly recommend Randy. Beyond his professional capabilities Randy is a genuine and wonderful human being.

Glenda Tuminello

Principal Consultant

Glenda’s background as an instructor and designer, has helped to shape the firm’s training, research and client perception programs. With over 25 years of experience, she is instrumental in supporting the firm’s research assignments, client perception studies and interpersonal skills training programs. Glenda has spoken with hundreds of clients who have readily offered their insights and feedback. Her interviewing skills and natural demeanor make her one of the best at getting to the heart of client issues. ​

We've probably received more value with Tuminello Consulting as our marketing consultant than with most of the consultants we've used.  They have done what they said when they said it.  In addition, I appreciate their ethical approach to business.
