About Chino Hills

Sundahl & Associates’ Chief Executive Officer and Licensed Private Investigator (PI), Shaun Sundahl is a current resident of Chino Hills, California. Actually, PI Sundahl moved to Chino Hills in 1999. The beautiful city of Chino Hills is well known for its high quality of life and beautiful rural atmosphere. The name Chino Hills fits the name of the city quite well.  The city rests on top of the hills of the formerly unincorporated areas of Chino. In addition, severalPrivate Investigators (PI) love to pass through the hills.The city holds more than 78,971 residents, almost 23,000 more people than when Mr. Sundahl first moved to this city! There are 3,000 acres of publicly-owned open space, 40 parks, and 39 miles of trails.  According to the 2009 FBI Crime Statistics, Chino Hills was named the 13th Safest City in the United States. That is exactly why Private Detectives and Investigators love to work in this city! As a PI residing here, Mr. Sundahl can attest to the lack of crime statistics since he was able to attend several Chino Hills Sheriff station ride-a-longs. Moreover, the city ranked #68 on the top “100 Best Places to live in the United States”. According to the American Community Survey, U.S. Census Bureau, the city has the 6th highest median income in the nation.

List of Detailed Services:

Attorney Support

Sundahl & Associates specializes in assisting attorneys with surveillance, locating, and interviewing witnesses, evidence gathering, and written documentation for tort, breach of contract, and worker’s compensation cases. Our CEO has a B.S degree and is currently studying law which allows him to have the upper hand over other investigators.

Child support investigations

Hire our Detective Agency to locate the “dead beat” parents who cowards him/herself to avoid paying child support and/or alimony. We have access to modern day tools used in the private investigation industry to locate those “dead beats.”

Criminal Defense Support

Have you been wrongly accused of a crime? If so, hire us to investigate your case.  We here at the Detective Agency have placed many people behind bars.  As former police officers, we know the loop holes of the criminal justice system and trust us, there are MANY.  We know how police officers think, behave, and act.  Something to consider: police officers do not often look for the eye witnesses who will testify on your behalf.  In fact, the police officer’s role is to help the prosecutor prosecute YOU. No matter if you have been accused for murder or DUI, no accusation is too small or large for our firm to handle. We at the Detective Agency have worked with great cops anddirty ones. It takes former police officers to understand the behavior of current ones.

Criminal Investigations

We offer criminal investigations; however due to conflict of interest (our lead investigator is an off-duty police officer), effective March 20, 2014, we will no longer provide criminal DEFENSE.

Employee Misconduct

Sundahl & Associates investigators are well versed in the law to avoid potential lawsuits against the employer.  If the employee is suspected of a crime, we don’t have the same restrictions police officers or detectives have. We specialize in interviewing and investigating employees suspected of violating company policy and/or criminal codes while observing local, state, and federal laws. No matter if the accusation is sexual harassment or violation of company policy, the Detective Agency will gather as much evidence as possible to prevent claims of wrongful termination.

Infidelity Investigations

Are you or someone you care about concerned about a significant other cheating? If so, call us NOW. We conduct undercover and surveillance operations so you can have a piece of mind. We don’t make any promises, but we will attempt to obtain the physical evidence you need to sleep better at night. Our service is discreet and whatever is mentioned in the office stays in the office. We can meet you in the field or in the office, whichever conveniences you. Our investigators will keep you up to date with pictures, video footage, and daily written reports. We won’t sleep until you sleep!

Mortgage Field Auditors

Are you an out-of-state or out-of-area mortgage auditing firm? All of our clients have listed us as preferred investigators in California. Call us today!

Missing Person Locate

Are you trying to find someone? Do you need to serve papers to someone and you have no clue where they are?  We here at the Detective Agency, specialize in locating people.  We have modern tools to locate those you need found. Click here to read our article on missing persons.

Police Misconduct

Have the police ever wrongfully placed their hands on YOU or a loved one? Did the police officer lie in her report in order to “lawfully” arrest YOU? If so, you are not alone. We know how some police officers “cover up” misconduct and lie for each other.  As former police officers, we know how to cross this “Thin Blue line” and collect the evidence you need to assist your attorney with litigation matters. We have the ability and courage to conduct covert operations such as surveillance, on the police. So when you ask who watches over the police, your answer is our Detective Agency.

Pre-Employment Screening

Do you really know who you are hiring? A small price to hire us for pre-employment screening, by far, outweighs the costs and damage a parasitic employee might cause to your company. We offer modern workforce solutions for the demands of today so you don’t have to worry tomorrow. We hand tailor our pre-employment package for the needs not of a company, but of YOUR company. Because every company or organization is unique, our investigations team will take the time to access your business needs and offer an array of solutions.

Tenant Screening

Are you a landlord? Do you need help screening tenants? We have access to modern technology to screen out tenants that might cause YOU problems in the future.

Several months ago, we located a history of evictions for our customer in Pennsylvania. The customer disregarded our findings and just recently had a problem removing the same tenant! Also, we were able to find that a prospective tenant had an arrest history for rape. Another had an extensive history of assault and battery.  Can you imagine trying to evict or collect rent on some of these tenants? Do you really know who is renting your property? Are you located out of the area or out of state and want to see that your tenant-landlord agreement is being adhered to?

For a small PRICE, you can reduce future COSTS.
