Helping Companies Turn Procurement Into a Competitive Advantage

Procurement Advisory & Mentorship

With decades of frontline procurement leadership, I now help organizations and professionals apply strategies that produce measurable results.
My approach is built on real negotiations and supplier relationships that generated hundreds of millions of dollars in savings throughout my career. Through Lean Source Solutions, I work with clients who want to strengthen supplier performance, sharpen negotiation skills, and achieve sustainable cost reductions.

Mentoring for Procurement Teams
Guidance for less-experienced buyers and sourcing professionals. I help identify cost-reduction opportunities, improve negotiation tactics, and execute supplier agreements that build long-term value.

Supply Chain & Contract Reviews
Independent reviews of supplier portfolios, contracts, and cost structures. I identify improvement opportunities and recommend strategies to strengthen leverage and reduce cost.

Consultation Offer
Every engagement begins with a complimentary 15–30 minute consultation to discuss goals and assess where Lean Source Solutions can add value.
