All of our training associates are industry professionals with decades of experience applying GD&T and teaching GD&T. Our associates have:

  • -expert knowledge of the Y14.5 standard

  • -current industrial experience using GD&T

  • -experience and skill using James Meadows' course materials.

Many of our associates are current members of the Y14.5 committee on Dimensioning and Tolerancing, are Senior Certified GDT Professionals and are active in the writing of multiple ASME documentation and measurement standards.

All of our associates use identical training materials and lesson plans so you receive the same topic presentation from every training associate; however, based on client company needs, some course topics can be emphasized, de-emphasized or added per request.

He teaches a wide variety of Geometric Dimensioning and Tolerancing and related topics, displaying a great deal of

flexibility regarding client company needs. Those course topics include: Basic and Advanced GD&T, Tolerance Stack-Up Analysis, Reading Engineering Drawings (Blueprint Reading Fundamentals), Inspection Methodologies, Statistical Process Control.

Mr. Cogorno has written his own book on GD&T, published by McGraw Hill. He has been a full-time technical trainer in GD&T and related topics for 20+ years. He has a great deal of technical knowledge regarding design, manufacturing and inspection techniques from a wide variety of industries and has offered GD&T and related topic training for the military and military contractors, the private sector, and for colleges and universities.

He holds an Associate's Degree from San Joaquin College and a Bachelor's Degree and Master's Degree from San Jose State. His degrees are in Engineering and Industrial Education.

James Keith

James Keith

James Keith and James Meadows have worked closely together as vice chair and chair of ASME Y14.43 (Gages & Fixtures Standard) since the late 1990s. Mr. Meadows knows Mr. Keith to be hard working, knowledgeable and innovative.

From James Meadows: 'I have a great deal of respect for his ability to teach others very difficult topics as they relate to GD&T and all of its different aspects. His experience in

manufacturing and inspection, as well as design, makes him the type of well-rounded individual most qualified to teach any aspect of GD&T and related topics.' He is passionate about teaching GD&T related topics and has been doing it for 20+ years.

James has worked in the following areas: 20+ years as engineering standards specialist; 10+ years in aircraft design checking; 7+ years as aerospace designer; Petrochemical draftsman; and Manual/Numerical Control Machinist and Set-Up Inspector.

James Keith's ASME standards committee affiliations, as listed below, are some of the most impressive of any individual in the United States.

ASME Y14.3/4 Committee (Orthographic and Pictorial Views)
ASME Y14.5 Committee (Dimensioning and Tolerancing)
ASME Y14.8 Committee (Forging and Casting)
Chair of ASME Y14.36 Committee (Surface Texture)
Vice Chair of ASME Y14.43 Committee (Dimensioning and Tolerancing -Functional Gages/Fixtures)
ASME Y14.45 Committee (Measurement Data Reporting)

ASME B89.4.21 Practical CMM Applications
Alternate Member AED Committee (Aerospace Engineering Drawings)
Owner of Critical Concepts consulting and prototype manufacturing shop


Dr. Patrick J. McCuistion

Dr. Patrick J. McCuistion

Dr. McCuistion obtained bachelor (1977) and master (1982) degrees from Pittsburg State University (PSU) and PhD (1989) from Texas A&M University (TAMU). All degrees were in Industrial Education with focus areas related to engineering drawing and mechanical design.


Jim Meadows has often said that Pat McCuistion has revolutionized the look of the ASME documentation standards. His 2D and 3D illustrations made clear what a

complete geometric product definition should be and explain complex geometric characteristic definitions, principles and measurement practices. His work in the Y14.43 standard on Gages and Fixtures was so ground breaking and impressive that he was immediately recruited as the creator of the Y14.5-2009 standards illustrations. Pat understands that the first thing people look at in books and standards and presentations is the illustrations, and his are simply the best.

He has eight years of experience working in various engineering design, drafting, and checking positions at various manufacturing industries (feed mills, dehydration facilities, automotive components, catalytic convertors, heavy equipment transmissions, and auto bodies).

He taught one year at PSU and three years at TAMU. As an associate professor in the College of Engineering and Technology, Department of Engineering Technology and Management at Ohio University since 1989 he has taught: Engineering Graphics Fundamentals, Engineering Graphics Applications, Geometric Dimensioning and Tolerancing, Dimensional Analysis, Dimensional Metrology, Enterprise Computer Methods (Microsoft Word, Excel, Visio, PowerPoint, and Project), Quality Management Systems (ISO 9001 and Six Sigma), Technical Writing, and Product Design.

He is an active member of the following ASME/ANSI codes and standards subcommittees: Y14 Main Committee, Y14.2 Line Conventions and Lettering (Chair), Y14.3 Multiview and Sectional View Drawings, Y14.5 Dimensioning and Tolerancing (Figures), Y14.5.2 Certification for Geometric Dimensioning and Tolerancing Professionals (Figures), Y14.8 Castings, Forgings, and Molded Part Drawings, Y14.35 Drawing Revisions, Y14.36 Surface Texture (Vice Chair, Figures), Y14.43 Dimensioning and Tolerancing of Functional Gages (Figures), and B89/Y14 Joint Committee on the Specification of Notation to Support Requirements for Size and Geometric Tolerances (Figures). He is also an ASQ member.

He has authored one textbook on geometric dimensioning and Tolerancing, three ASME internet courses in Drawing Interpretation, Basic GDT and Advanced GDT, and 15 technical articles on dimensioning topics and computer aided instruction.

He is an ASME certified Senior Geometric Dimensioning and Tolerancing Professional and an ADDA certified Mechanical Drafter.

Rick Hughes

Rick Hughes

Rick is one of the most productive workers on a wide variety of ASME standards committees dealing with GD&T principles and applications and measurement, inspection and gaging.

He is a current member of the Y14.5 Dimensioning and Tolerancing standards committee and a founding and current member of the 14.43 standard on Gages and Fixtures. He not only knows the theory of tolerancing but

also how to apply its principles to measurement, manufacturing and design.

Jim Meadows often says that Rick is one of the most intelligent individuals he has ever met and has a wide range of knowledge on GD&T related topics.

In his long career, Rick has often worked two jobs: one in the aerospace industry and another as a college professor. This gives him a great deal of practical knowledge and lots of experience explaining it. He has also been teaching GD&T in industry (aerospace and other industries in the LA area) and at the college level (in the CADD and Engineering Technology departments) for about 30 years.

His ASME committee affiliations include: Y14.5 (Dimensioning and Tolerancing),Y14.43 (Dimensioning and Tolerancing Principles for Gages and Fixtures), Y14.45 (Reporting Inspection Data) and B89/Y14 Joint Working Group (Special Notation for Size and Geometric Tolerances).

He is an ASME Certified Senior GD&T Professional (Cert # 0143). He has a B.S. degree in Applied Science and Technology (Area of Specialization: Engineering Graphics) and a Masters of Education (MED) degree (Area of Specialization: Learning and Technology).

Rick loves teaching GD&T and related topics and his students are in for a rare experience: an instructor who thoroughly knows his topic, conveys it with warmth and understanding, and genuinely cares about how much everyone in the class learns.
