Shane Coleman

Excellent course. Very informative and beneficial.

Elizabeth Mary Doyle

It would be hard to improve this course, as it is very well delivered at each lecture.

Shane Costello

John has a very friendly and approachable manner, and a great ability to keep the focus of the class.  Because of my studies with City Colleges, I now have a strong desire to further my education.

Hannah Quinlan

John is a very good teacher, and at getting points across.  He has an obvious interest in the subject, which makes the lesson interesting as he is not just reading  off information.  He is humorous and brings a laid-back atmosphere to the class, making it enjoyable to sit through each week.

Michelle Hourihan

John is engaging, entertaining and knowledgeable.  His enthusiasm for the subject matter is contagious.  He has a huge breadth of knowledge and this enables him to link a wide variety of text, cases and individuals to bolster each of the subjects. John is always punctual and has a mix of text, video and spoken matter readily prepared to impart to the class, ensuring that all learning styles are catered for. I would gladly recommend this course to anyone considering an associated career or anyone who has an interest in criminology and would like an informative and entertaining short course.

Detective Garda Ann-Marie Larkin

I would highly recommend the course to anyone, especially any one in the Gardai like myself.  If you have an interest in Crime/Branch in particular, then this course is definitely for you.  Extremely interesting but also highly relevant for work related purposes in a wide variety of areas in relation to crime investigation. Brilliant to have on your CV.  It was worth every penny.  I travelled from Cavan to Dublin once a week for the course and it was well worth it.  I cannot recommend it highly enough.

I believe that this course should be delivered to every member of An Garda Siochána it is very relevant to modern day policing.”M O’Callaghan“After moving from South Africa to Holland at the age of 43, I decided I wanted to grow my knowledge in the areas that I have always been passionate about. I enrolled with City Colleges to do the Diploma in Criminology & Criminal Psychology online. 
From the very first contact I had, it has only been a pleasure. Sarah was ever so helpful and John incredibly informative with regards to all my questions prior to enrollment.
Paying the very affordable fees and receiving my login details was done efficiently. Studying via correspondence always made me think that it would be impersonal and I wouldn’t get personal attention when and if I had issues. I am thrilled to say that this was not my experience. The class given was prompt, it was professional yet never boring or tedious. John has a vast knowledge of Psychology and Criminology and the way he carried that over to his students (me) was passionate. The attention to detail and the study material supplied was always timeously loaded onto the system and I could access it at my leisure. The lecturer engaged with the class (even though I wasn’t physically there I was able to hear and understand their feedback or comments). He was also an entertaining man, if at all possible with criminology.
I never had an IT issue but if I had questions regarding this the query could be emailed through. Sarah is a star and I hope to be dealing with her again in September.
I have enrolled in my next course and I would encourage anyone who wants to further their education in the comfort of their own home, on whichever continent, to do so and City Colleges is a great institution to do it through.
