Crespo will lead quality and compliance at Pinnacle and oversee compliance across TPC specialty manufacturers, strengthening the systems that support growth in aerospace, defense and medical manufacturing

Anaheim, Calif., November 12, 2026 – Pinnacle Precision (Pinnacle), an Anaheim-based specialty manufacturer and part of The Partner Companies (TPC), today announced the promotion of Arturo Crespo to Vice President of Quality and Compliance. Crespo will lead Pinnacle’s quality and compliance strategy, overseeing its quality management, regulatory compliance, supplier quality and cybersecurity-readiness programs, including the company’s AS9100 system and CMMC readiness. He will also oversee compliance, certifications and registrations across fellow TPC manufacturers L&T Precision, UPG and F&B MFG.

The newly created role reflects TPC’s continued investment in the systems and leadership needed to meet rising quality and compliance expectations as it serves highly regulated industries, including expanding cybersecurity requirements across the defense supply chain.

Crespo brings 20 years of quality assurance experience across the aerospace, medical device and electronics industries. He has a proven record of strengthening supplier quality, deploying zero-defect manufacturing and leading customer and registrar audits with no major findings. He is a Six Sigma Black Belt and holds the American Society for Quality (ASQ) Certified Supplier Quality Professional and Certified Quality Auditor credentials, with lead-auditor qualifications spanning AS9100, ISO 9001, ISO 13485 and IATF 16949.

“Arturo has already raised the bar on commitment to quality at Pinnacle,” said Luis Gomez, Group President at The Partner Companies. “This role reflects our investment in the people and systems that let us scale quality and compliance as the business grows, and Arturo has the experience to build programs our customers can count on.”

In 2024, Crespo joined TPC to lead quality and compliance for both Pinnacle and L&T Precision. He previously held quality and supplier performance roles at Panasonic Avionics Corporation and Freudenberg Sealing Technologies, and managed aerospace programs at Hutchinson Seal Corporation. Crespo holds an MBA from Universidad Tecnológica de México (UNITEC) and a B.S. in Electronic Engineering from Universidad Autónoma de Baja California.

“Quality and compliance work best when they’re built into how we operate every day,” said Crespo. “In this role, I’m focused on building on the systems, processes and standards that support growth at Pinnacle and across TPC, and give our customers confidence in every part we deliver.”

Crespo will be based at Pinnacle’s Anaheim, California facility.
