About Us

I started Allen Investigations in 2004, but I have always been in the business of helping people in some capacity, starting with my career as a San Bernardino County; Sheriff’s Deputy, where I worked as a specialized detective in the Crimes Against Children Division and the Homicide Division.

I retired from the Sheriff’s Department and became a Riverside County District Attorney’s Office Senior Investigator, where my investigative skills were honed.  After retiring from the District Attorney’s office, I knew I couldn’t let my 25 years of investigative experience just sit and collect dust.

Why use a Professional Bail Bond Company?

In general, the answer is money. If you don’t have 100% of the bail amount, you may be able to come up with the 10 – 15% premium charge that a bail bond seller collects in order to post bail. This premium is non-refundable, it is a fee collected by a bail bond seller to ensure compliance with release and attendance at court appearances. There are benefits to this system, a bail bond seller understands the process and can help guide you through the system at a time when you are most likely to be under pressure and stress.
