Client and Student Testimonials


Taking Peter’s class helped solidify the at home readings to prepare me for the APICS CSCP test. Peter added in his own insights from his career to further teach the materials in an interesting way. In addition to the slides Peter also created extra practice questions and was always available for extra help or guidance. You can tell Peter is passionate about the subject matter which makes him an excellent teacher! Peter’s class helped me pass the test the first time and further my supply chain acumen!

” I am so pleased that I took the time to enroll in Peter”s CSCP preparation class.  Peter made each class entertaining while explaining the concepts of supply chain to our small class. The intimate class size allowed for each of us to ask questions and relate our real world experience to help visualize what we have learned.  What quickly became apparent was Peter’s desire to see us succeed. The course and online practice exams have been invaluable while I prepare for the certification exam.”

Loren Paschall-Smith, CSCP

I took a CSCP exam preparatory course with Peter J. Blok, which I can gladly call money well spent. Peter draws upon decades of experience in the industry in order to provide color and relevance to material that is crucial to success in not only passing the exam but also in long term professional growth – Peter really takes the time to cover all of his bases. Speaking of time, Peter made himself available outside of the designated meeting hours to answer any questions that may have come up from the material or the practice exams and that availability was priceless in itself given the ‘always on’ nature of the supply chain industry. Peter even took the time to follow up with the group long after his obligation was met to check how we progressed in our preparation – he seemed genuinely invested in the success of the group.

I have since earned the CSCP designation and would seek out future certification prep courses led by Peter because I know what I’ll be exposed to – years of experience and a wealth of knowledge.

Michael Szabados, CSCP

I recently completed my CSCP certification and I am so glad that I enrolled for Pete’s CSCP learning sessions. His years of industry experience and deep insightful supply chain knowledge makes him an ideal mentor for anyone embarking on the CSCP certification journey. He is truly passionate about the Supply Chain subject which is noticeable in his classes . All through the course of the learning sessions, he kept the sessions interactive and interesting with a lot of real world examples and encouraging shared learning via discussions. As his student, Pete provides all the resources in terms of practice problems, practice test questions, reference materials and most importantly his time if needed to help understand a topic better. I would highly recommend Pete to anyone looking for an enriching learning experience towards completing their CSCP certification.

I participated in Peter’s CSCP class that started in April 2023. He was a very well informed instructor. He was able to share real life examples to connect the course content through his prior experiences and expertise. He was very receptive to any questions we had and always offered to help during the class or in separate 1:1 sessions if we needed. He shared many useful tips specific to the CSCP exam that definitely stuck with me during my prep for the exam. I would highly recommend Peter and his course for those interested in obtaining the CSCP certification.

From the beginning, Peter’s comprehensive understanding of the subject matter was evident. He had a unique ability to simplify complex concepts, making them easily digestible and retainable. His real-world industry knowledge helped solidify understanding and made the material more engaging, which made the learning process enjoyable. Peter also went above and beyond to ensure that I was well-prepared for the exam, providing additional resources, and making himself available for questions and clarifications outside of class hours. Thanks to his guidance, I was able to pass the CSCP exam on my first attempt! I highly recommend Peter’s class to anyone seeking to pass the CSCP exam. His dedication, expertise, and effective teaching methods will undoubtedly equip you with the knowledge and confidence needed to succeed.

“I completed Peter’s CPIM 1 and 2 courses and passed my CPIM exam on my first attempt! I can’t recommend them enough. Peter has extensive industry knowledge. He shared many relatable examples during classes which helped me better understand topics. If you have questions or need additional help understanding a concept, you are able to schedule time outside of class with him which is super helpful. I highly recommend!”
Zach Clifford, CPIM

“Dr. Blok is extremely knowledgeable in the end-to-end supply chain. I took his 13 week course and throughout the course he kept the class engaged by asking questions and showing videos. He answers all of the questions/doubts, very hands-on. He also helped me offline and gave me all the time I needed so that I feel confident about my exam. All-in-All, he’s a 10/10.”

I highly recommend the CSCP certification prep class run by Peter.  Not only does he know the material, his real-world experience in the Supply Chain industry and the stories he tells brings the information to life. 

Peter adds an additional level of understanding and real-world application of the CSCP curriculum.

“Pete Blok’s CPIM course not only gave me the knowledge of the inside four walls of a company/plant but gave me real-life examples and developed my critical thinking of supply chain outside of my industry.”

Howard Klamo, CPIM

Business Analyst - SAP Supply Chain Integration, Conagra Brands

“ I am very lucky to have Peter Blok as my instructor, without his help, I don’t think I can pass CSCP exam the first trial.

I have many years of purchasing experience, but I am not familiar with forecast, or manufacture, or IT. Apics “ language”, as Peter put it, was difficult for me to understand, but Peter has his special way of making difficult things easy to comprehend, and explaining those abstract concepts with vivid examples from his own hands on experience.

Two months after I attended peters classes, I advanced closer to CSCP; still, I wasn’t confident that I could pass the exam. Peter generously shared his busy time for extra hours of personal help to answer all of my questions, and strengthen my understanding. All of sudden I felt CSCP materials made sense.

Peter knew that I tend to be nervous when answering questions, he urged me to have confidence in myself and stay calm to get the best out of myself in the exam. I stayed focused and calm during the 3 1/2 hours and made it! I am grateful to God for sending an awesome instructor like Pete”

Anne Chen, CSCP

I completed the CSCP certification prep course with Peter after he was recommended to me by a colleague. He has such a breadth of industry experience and is extremely knowledgeable on the APICS content and test material. I thoroughly enjoyed the classes, which Peter always kept very interactive and would even sprinkle in a few jokes here and there. Peter made himself available after class hours for additional questions and one-on-one extra help sessions. After completing the course, I passed the CSCP certification test on my first try and feel confident that I can take all of the learnings with me through the next steps of my career in Supply Chain.

Peter went above and beyond what I expected from this course. He was eager to help and always responded to questions promptly. I give him all the credit for my understanding of the vast majority of the text material. Now that I’ve completed my CSCP, I look forward to taking the CPIM course with Peter as well.

Starky Bibb, CSCP, CPIM


I was pleased to meet Peter through Linked-In, where I read many positive reviews about his classes. I’m glad I enrolled with Peter for the CPIM II class, as he was able to link the text material with “real-life” experiences. We had a small class which allowed us to connect each other’s businesses to the text materials, which I found very interesting. Peter made sure that we all understood the weeks’ material before moving onto the next topic. His classes were prompt, well organized, and extremely professional. Peter was available for questions throughout the 15-week semester and has offered his help even after the class has been completed. I can see myself calling on Peter’s experience well down the road in my career. I would recommend Peter’s classes to those looking for a down to earth atmosphere, but yet full of rich knowledge
Stephen Liberty, CPIM


I had the opportunity to take the APICS CSCP course when my company offered an onsite class presented by Dr Blok. Attending Dr Blok’s class weekly was incredibly helpful as he walked us through the material and answered all our questions. With his real-world experience, he was able to connect the text to examples we could understand and relate to. APICS has empowered me to develop my career and today I hold a leadership role in my company’s supply chain. Dr Blok has been an expert voice I have called on time and time again for guidance to develop my supply chain and staff over the last two years.

Dr Blok, thank you so much for your insights. I value the guidance and support you provide. I look forward to my team taking the APICS CSCP with you in the coming months

“I found Pete Blok’s APICS CSCP classes to be very interesting as he cites real world examples to explain Supply Chain concepts and constantly encourages interactive class discussions. This enables easy understanding and remembering of the lengthy modules. Pete has also been responsive to my email queries on quiz questions or other topics until the day of my exam. His consistent guidance and support helped me greatly to receive my CSCP certification. Thank you, Pete!”

“I and handful of my team signed up for Peter’s CPIM class in 2022 & 2023. I have to admit, I was a bit hesitant on the process and material before I started. Mainly based on the assumption of how niche the industry I’ve always worked in is. What I found as we got into it though, was nothing short of amazing. His additional content above the standard offerings helped to connect the material to real world scenarios I and my team understood very well. His commentary helped link what we were studying, directly to the industry we all worked in. His years of experience in that same industry really helped drive home the connections of theory to our everyday lives. More than all that though, he was kind, funny and very intelligent human being. Taking time to discuss personal concerns, life experiences and general family conversations. I cannot recommend this class enough. Whether you’re just starting out in supply chain, or you have 20 years in various roles and industries, there is something in here for everyone to learn.”

I was lucky to enroll in a CSCP Prep class taught by Peter Blok (OFI) through my workplace. I’ve got years of supply chain experience, but it was – as they say – an inch wide and a mile deep. Many, if not most of the concepts we learned in class were new to me. Still, I never felt uncomfortable or silly for asking questions or for clarification. Peter did a great job engaging the class and relating material to current events such as the Covid pandemic, the war in Ukraine, and items in the news relating to major corporations. I felt ready and prepared to take the exam because of the study guides he provided, and the way he taught us to consider answers. I’m proud to say I passed the exam on my first try. Peter was the first person I told!

 I was pleased to meet Peter Blok when he was selected by Bristol-Myers Squibb to offer a preparatory class for supply chain professional certification [CSCP] to a class of seasoned professionals.  No easy task – he totally got it that I was seeking formal accreditation for my work over the last 20 years.  Pete supplemented the APICS materials with his own customized materials that added extra context and clarification.  I was delighted that he was so personable and thoroughly knowledgeable in the subject matter.  Learning was energetic and fun.  When we asked questions that were not the most insightful, his professional, diplomatic, and empathetic approach was able to get us over the bumps in the road.  I am pleased to report that, so far, all of those who took the exam after Pete’s preparation have passed.  Real results from a real professional – I am very grateful, and I highly recommend the services of the OFI group.

Pete taught an onsite CPIM 1 class to me and 22 of my colleagues.  He was able to cover all the material in 7 weeks, he shared his expertise and years of experience in supply chain, and he worked hard to make a connection between the theory and our actual business.  Everyone from the class that took the exam passed, and I look forward to working with Pete in the future.
