A Good Experience for Me

Validation was a good experience for me, since this was first time I validated a program. As a team, we learnt a lot about why validation is important as well as figured out some loopholes within the system. Without David, this process would have been impossible. He was great to work with and also was instrumental at figuring out the loopholes within the system.

Your training class was extraordinarily beneficial in our efforts to advance to advance our Part 11 initiative.

Almost Immediate Implementation

I wanted to say that I really enjoyed the Computer System Validation class in San Diego and I've been able to implement ideas you presented almost immediately upon my return.

- Seminar participant

At a Critical Point

At a critical point in the validation project senior management promptly approved the contract to hire David Nettleton, one of the nation's leading consultants. Without David Nettleton, the project would have not gone live as scheduled and would not have been compliant with Part 11.

Best speaker

Best speaker of the conference. Outstanding material, technically correct, and good regulatory interpretations.

- Conference delegate, San Diego, CA

Bridged the Gap

I can tell David has a lot of experience with computer system validation because David bridged the gap between IT, QA, and Clinical.

Comfortable Now

I wanted to take a moment to that you for yesterday's presentation.  Not only was it educational and enlightening, but it was also very entertaining. It was actually a pleasure for me to attend.  Of course, I still have many validation questions, but am very comfortable with the concept now.

Excellent Teaching Skills

I want you to know how thankful I am for the excellent training that I received during these two days in June 2006. Not only the content of the course was great, but your excellent teaching skills made the course easily memorable and understandable. There are two words to express my opinion about the course "made professionally"! Besides that, I really appreciate the numerous hints that were generously given to us - these are priceless.

Excellent, Excellent, Excellent

I want to thank you for bringing in David today.  It was Excellent, Excellent, Excellent.  We are trying to pin down our process and procedures and this really gives us a better sense, at least for a 21 CFR Part 11 standpoint, of where we should pay attention.  All I can say is when can we get more.

Eye opening

Many thanks for your eye opening course this week. It was exceedingly useful to hear from someone who has practical real-life experience rather than someone who is simply interpreting the regulations.

Fantastic workshop

I attended today's workshop, "Implementing and Sustaining a Records Systems That Will Meet Regulatory and Intellectual Property Requirements" at the Pennsylvania Convention Center, which by the way I thought was fantastic.

Great Two Days

First I wanted to thank you for a great two days packed of wonderful and very useful information.  I have been to Part 11 seminars before but this was the only I walked away with a clear understanding of what is required, why, and how to perform it correctly.

- Seminar participant

Helped us leap

You helped us to leap from having ‘0’ process to having a reproducible system to produce quality validation and SOP document. Super effective learning.

How Useful Your Course Actually Was

I'm currently sitting in a software training course that is definitely not worth the time away from my job, and it reminded me of how useful your course actually was.

See the True Fruits of Your Labor

She [the auditor] said the audit package we presented was the best she had seen (and she is extremely experienced). She is very impressed by how clean, easy to follow and thorough your resulting product is. David, sometimes you cannot see the true fruits of your labor until some time and events have passed.

- Pharmaceutical QA Director, Houston, TX

Seminar cleared up questions

I really enjoyed last week’s COTS Software Validation class.  Thank you for spending a good amount of time on explaining the specifics of 21 CFR Part 11.  This was the area I needed the most help understanding and you did a great job of clearing up any Part 11 questions I had previous to the class.

Small Business Needs

David understands the needs of a small business and was able to provide us with great value. His understanding of his field is detailed and confidence inspiring. He is an effective teacher who doesn't want to keep coming back and charging more and more - instead he made us self sufficient, capable, and confident in our compliance needs. He is a very hard worker who makes the very most of his time with clients.

- Client, San Diego

Superb training

On behalf of all of us here, I want to thank you for a superb training session today.  What you taught us is exactly what we needed and I look forward to the journey working with you over the next 6 months as we get our act together for FDA compliance.

David Nettleton was very clear and concise on a confusing subject. He had my complete attention (during lunch that is not easy). Wonderful delivery of timely information. Excellent job.

The Best Training I've Had in Years

I took your "Complying with Computer and Software Validation Requirements" through PTi in February (San Diego). This is just an unsolicited positive review of that course -- I've since had a couple of other training courses (completely different topics, completely different companies), and I just wanted to let you know that your course was probably the best training I've had in years. I've told anyone who asked that I'd recommend your course to others, no question.

The training helped with our internal CSV procedure

I attended your 2-day CSV course "Electronic Records and Signatures:  From 21 CFR Part 11 to HIPAA" via the UC Santa Cruz extension program (during the Winter 2008 term), and would like to thank you for a very informative course.  The information was very helpful in drafting my employer's internal CSV procedure.

University Course Feedback

Experienced and enthusiastic instructor.

Got me to think about validation a different way, the end users’ perspective.

The instructor’s knowledge of the subject was outstanding.

David was a very lively and dynamic teacher. He has extensive knowledge of the topic and has many supporting real life examples.

He made regulation fun.

The course exceeded my expectations.

Great course.

- U of CA Students

Very Impressed

I was very impressed with your presentation and the energy you put into the event. You should know that the staff left the teleconference very excited. I am a bit surprised at the level of excitement, but I think it is due to the fact that you demystified many topics that had become complex and complicated.

Your training course was phenomenal

I just wanted to thank you for all of the insight that you provided over the last few days.  Your training course was phenomenal.  I wish all teachers shared your laid back, fun, and example-based approach.  It was great that you took the time to figure out what was important to all of the folks in your audience.  It really made the learning personal.
