Alex Young, Senior Acoustics Consultant, started with Cass Allen in 2015            

“After previously working in the education sector I started work at Cass Allen whilst studying for my IOA Diploma. What I immediately liked about the company was the wide range of projects I got to work on straight away and the opportunities I was given to progress at my own pace.

I like to think of myself as being quite motivated, so for me Cass Allen was the perfect choice as I was able to take on quite a lot of responsibility quickly and get involved with large, interesting projects.  Since starting I have been promoted to the position of Senior Consultant and continue to develop my skills and understanding day by day.

I would highly recommend working at Cass Allen to anyone with an interest in acoustics who is willing to put the work in, as it really is a place where hard work is recognised and rewarded.” 


Alex Clark, Acoustics Consultant, started with Cass Allen in 2017            

“I started working at Cass Allen after having graduated from Southampton University (ISVR) with a degree in acoustical engineering. Over the last year and a half I have thoroughly enjoyed working on a vast array of projects in many different areas.

Unlike many Junior Consultants working at other companies, I have been encouraged to work on all aspects of the job from writing fee proposals, carrying out site surveys, writing reports and talking to clients on the phone, to attending meetings with large developers and architects.

My work has included travelling all around the country to measure various types of noise (which often requires enjoyable investigations into understanding the nature of the noise source), and sound testing expensive flats in central London.

Due to the large, friendly team at Cass Allen, I have quickly learned how to liaise with councils and write politically sensitive reports, and have vastly increased my knowledge of both environmental and building acoustics.

The lively environment at Cass Allen has been the perfect place for me to transition into the professional world, and has set me up well for a long and rewarding career in the industry.”
