Mr. Gaziano is a wealth of knowledge when it comes to Forensics. He is recognized worldwide for his superior understanding and teaching of Blood Stain Pattern Analysis. I took his course twice and each time I learned something new. He made this class fun with his own handmade practical exercises not used in any other courses. Calvin is a true mentor and I learned a lot from him over the years. You will not be disappointed with any course he teaches.

John is an excellent teacher and does an amazing job teaching his courses. I have testified in court on major cases, because of his instruction, which was both demonstrative and hands on. I was not only a student, but a participant in scientific experiments during his class, which helped my testimony. I highly recommend his courses and his experience as a consultant.

Ed Rudolph

Calvin Gaziano's bloodstain pattern analysis course was great! Lots of information packed into classroom and hands-on experience. We experienced finding the trajectory of spatter through recreating scenes and examining the evidence. We created a chart to reference what degree blood dropped from. Gaziano also provided us with a binder full of information for the course that we were able to take home. Everyone in my class passed the final test for the certification. Highly recommended!

In 2013, I attended the 40-hour Bloodstain Pattern Investigation course with John Calvin Gaziano as the instructor. Calvin has an effective teaching method, which is clear and concise. During the hands-on training, he broke us into groups and gave each group multiple bloodstain patterns to identify. Because of Calvin's instructions, I can perform the stringing method within bloodstain spatter to identify the area of origin and I can identify the area of convergence. Due to Calvin's guidance throughout the years, I am certified in court as a Bloodstain Pattern Analyst.

I took Mr. Gaziano’s bloodstain pattern course many years ago. To this day, I still have the binder he passed out in his class. He is extremely knowledgeable, passionate, and an expert in this field. His course was filled with fun experiments and had many learning opportunities. I highly recommend Mr. Gaziano’s class!

Candace Cook

Calvin Gaziano is a stellar Crime Scene Investigator and blood spatter expert. He breaks down the material so succinctly and thoroughly to make a laymen like myself understand it. He is one of the few IAI certified blood stain pattern analysts in the world. Excellent all the way around!

Jenn Ly

I have taken Calvin’s bloodstain pattern course twice, and I can’t say enough positive things about it. It is taught in a way that an entry level investigator or even the most senior would get a ton out of it. After taking his course, I had a much better understanding of what I was seeing at crime scenes. I would highly recommend this course for anyone who has anything to do with crime scene processing or investigation.

Don

This class was amazing. From the lectures, to the hands on experiments it covered everything! My training binder has not only been a constant resource for myself, but others at my lab who weren't as lucky as I was to have taken this class.

Megan Shaw

This class is one of the best I’ve taken. Calvin is a great instructor! Highly recommend this course!

Steve Hunt

Calvin is so incredibly knowledgeable with what he teaches in his course. He even incorporated his own research and thesis into his class. I also really enjoyed the experience I gained with all of the hands on activities we did!

Kaylee Fitzpatrick

This course was extremely informative, and was put together very well. Great course, I recommend it.

Amir Mahmood

Very knowledgeable instructor who breaks down difficult concepts into easy to remember concepts with insightful hands on practicals.

Five golden stars representing a 5-Star Review for John Calvin Gaziano - Pinnacle Forensics

When I lost my little brother to suicide under questionable circumstances, we were left with many questions – questions we believed the police had the answers to. Unfortunately, the official investigation left glaring gaps in procedure that raised more questions than it effectively answered. Protocols weren’t followed, conflicting accounts were overlooked, and evidence was not documented at all or never explained.

The hell of not knowing at times felt almost as rough as the day we got the message about his death.

I had no idea where to turn, but I looked up experts in the forensics field and found Pinnacle Forensics. The website was impressive and professional, so…. what the heck? The worst they could say was no.

Only, John did not.

Pretty much immediately, he stepped in and offered his expertise pro bono, a full review of everything physical I had been able to obtain regarding my brother’s death. I still don’t know why he did, but it has meant the world to our family.

His assessment was not only technically precise but also profoundly humane. He reviewed the case materials with care, outlining inconsistencies, explaining findings, noting issues in the original investigation while also explaining complex forensic processes and analyses in language we could understand. His analysis was meticulous and methodical and fully objective, granting my brother the respect in death he had not been granted at the time of his passing.

This meant more to us than just a professional report, it meant closure on the big questions. It’s a testament to how, despite the technical nature of forensics and the exacting standards required to become an expert, it is, at the end of the day, still a field a deeply human field, one about finding truths, however hard they may be to hear, for those who need them.

John’s commitment restored a measure of dignity to my little brother’s memory and helped our family move forward. He didn’t have to do any of that, but I’ve come to realize that’s the type of amazing person he is.

We are deeply grateful for his generosity, both in giving his time and in lending his expertise to ensure that the truth was not relegated to obscurity.

And for that, our family will always be thankful.

John, I know you had to see difficult things just to bring us closure, so I’m sharing this photo for you to see my brother as he was – and as I choose to remember him, smiling.

Thank you for all you did for us. I will never forget it.
