####  "professional and detailed"
Grant was our sales associate, did a great job explaining all of our options. Was very professional and detailed about answering the many questions we had. Would highly recommend. - [Lin R.](http://www.yelp.com/user_details?userid=0SdZcVj6U1mgSrmmFnWnzA), **King, CA**

####  **"Rarely give reviews on yelp but I would highly recommend this company! "**
I heard and read so many negative things about alarm companies and alarm systems. And ADT was no different. After calling several alarm companies, the only company that answered the phone was California Security Pro. And when I called back to make an appt (not expecting a person to answer at 8:30pm at night) someone actually answered the phone! I am also impressed with [Grant Fecher](https://www.californiasecuritypro.com/adt-ventura-county/adt-simi-valley/california/local-security-consultant). He was friendly, professional, efficient and made the process so easy. I rarely give reviews on yelp but I would highly recommend this company! Cost is very reasonable and the [service](https://www.californiasecuritypro.com/bakersfield-security-companies/california/daniel-zartner) is great!
