Testimonials

What students say about the course instruction and training experience

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.

Chris Wilson Fremont Police Department

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.

Elona Porter Lake County Sheriff’s Office

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 Marin County Sheriff's Department

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.

In my 25 year career in Law Enforcement, this is the best Blood Pattern course I have attended. I highly recommend this course. Great course and great instructor.

Margarita Strahan Aransas County Sheriff's Office

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 Fremont Police Department

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!

Grace C Fremont Police Department

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 Fremont Police Department

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 Fremont Police Department

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 San Francisco Sheriff's Office

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 Santa Clara County Crime Lab

Calvin Gaziano is an exceptional instructor. His lectures and scenarios were easy to follow along and are all real life crime scenes. With his training and experience, I felt comfortable and confident to learn, going into the photography class. I would recommend his class to other fellow crime techs in my area. I hope to attend more future classes taught by him!

Cynthia Gomez Odessa Police Department

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

100% recommend this class! John not only gave great lectures, but included a lot of hands-on exercises. As someone new to this field, I feel confident enough to go and take photos at any scene.

Crystal Carbajal Rockport Police Department

Even though I am not knowledgeable in photography, this course allowed me to better understand taking photographs and their importance. The instructor is extremely knowledgeable and helpful in trying to help others have success. I would highly recommend this to anyone who uses photography in any type of crime scene work, especially if it is on a regular basis.

Noah Hood Longview Police Department

WOW!!!! This was an amazing course over bloodstain analysis. Cal’s class is well planned out with labs and lectures over the material. This was the best continuing education course I have taken. The instructor has really refined his craft and had engineered tools and lessons that would be meaningful to investigations where blood is found.
