John Calvin Gaziano is a crime scene expert with multiple college degrees and crime scene certifications. He has over 27 years of law enforcement experience, retiring as the crime scene unit sergeant of the Fremont Police Department.
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.
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!
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.
