Going unnoticed is important when handling a case and is one of the reasons our Santa Ana investigators do not live in the area.

Private Investigator in Santa Ana



If a case lasts for just a few days or several months our professional Santa Ana private investigators are capable of making certain that it is properly documented and put together to ensure it cannot be refuted, even by the best opposing attorney. In fact, we have developed relationships with Santa Ana attorneys, many who know they can call on us anytime to put together the missing facts necessary to win a case.
Some of the technology we use in our surveillance are video cameras, still photo cameras, unmanned cameras, radio communication systems, motion detection cameras, and unmanned aerial surveillance. With our firm you have access to any technology necessary to make certain your needs are met.



While we make unmanned aerial surveillance available, most situations do not require such extreme measures, yet they do require long term monitoring, which in itself can eventually become costly. This is why we have perfected our use of unmanned cameras; with unmanned cameras, we can oftentimes surveil an area for 7-10 days for the same cost as a single day of manned surveillance. This use of technology makes it possible for us to build a case while at the same time remaining an affordable service.

Part of California’s Greater Los Angeles Area and the thrumming heart of the Santa Ana-Anaheim-Irvine metro area, beautiful Santa Ana is the county seat of Orange County. Santa Ana is also bordered by Tustin, Orange, Garden Grove, Westminster and Fountain Valley. At the south end of Santa Ana is a region shared with the City of Costa Mesa, the South Coast Metro Area. Nestled between the Santa Ana River and the Santa Ana Freeway (Interstate 5), Santa Ana is a convenient hop, skip and a jump from the coastline and the gorgeous, surf friendly shores of Huntington and Newport Beaches.


Santa Ana enjoys a Mediterranean climate, with warm, dry summers and mild, wet winters.


Santa Ana ranks as the 57th most populated city in the nation with a tenth of what is well over 3.09 million residents in the Santa Ana-Anaheim-Irvine metro area. Santa Ana is also the fourth most densely populated city behind New York City, San Francisco and Chicago. The median age in Santa Ana tends to be about 30 years, which is hardly a surprise given that the cost of living in Santa Ana is 9.1 percent lower than the rest of California.


Forbes has also ranked Santa Ana as the 76th best place for business and careers (out of 200 cities nationwide that merited ranking). Santa Ana scored even better in Forbes’ ranking for education (26th), and made the top 200 for job growth. With a job growth rate of 2.3 percent and an unemployment rate well under the national average (5.9 percent compared to 7 percent), it’s clear that Santa Ana will continue growing.


One of the major industries in the Santa Ana region has been aerospace, especially with Lockheed Martin. The predecessor to the modern defense contractor, the Glenn L. Martin Co., was founded in Santa Ana in 1912, and Lockheed Martin maintains a corporate office in Santa Ana to this day. While technology also plays a big part in Santa Ana‘s economy as home to the headquarters of companies like Xerox, T-Mobile, Ultimate Software, STEC and TTM Technologies, Santa Ana employers also include the county, USPS and local colleges.


Like other cities on the Southern California coast, Santa Ana began life as “Hotuuk” with the Tongva nation. The name Santa Ana began when the region was rediscovered by Gaspar de Portolá’s expedition in 1769; then it was named Vallejo de Santa Ana. The area was renamed Rancho Santiago de Santa Ana when the land was granted to Jose Antonio Yorba in 1810. The location was largely utilized as a mustard field when the Santa Ana area was purchased in 1869 by William H. Spurgeon; thanks to his early efforts and a major vote to separate from Los Angelas County, Santa Ana incorporated as a city in 1886 and became the seat of Orange County in 1889.


Population growth started to take off when the Southern Pacific Railroad built a line to Santa Ana in 1877, but in 1901, when the Pacific Electric Railway built a line through Santa Ana from Los Angeles, business and population really picked up. The Second World War brought another population boom, both because of Santa Ana Army Air Base and because of the veterans that moved back to Santa Ana after the war. While Santa Ana did experience a slump in the 1960’s and 70’s, its revitalization and redevelopment efforts have characterized the city since the 1980’s.


This has led to a thriving arts district, the Santa Ana Artists’ Village centered around Cal State Fullerton’s Grand Central Art Center, as well as upkeep and reopening of historic locales like the Yost Theater, Spurgeon’s original courthouse, and Orange County’s Original Courthouse, which was built in 1901 and remains the oldest county courthouse still standing in Southern California.


Santa Ana also boasts the oldest church, the Episcopal Church of the Messiah, which has been in continual use since its completion in 1888. Similarly, the Santa Ana Historical Society maintains the Dr. Howe-Waffle House and Medical Museum, which was built in 1889 and is listed as a Historic Point of Interest on the National Register of Historic Places. Santa Ana is also home to the Kellogg House at the Heritage Museum of Orange County, built in 1898.


Santa Ana has its fair share of museums as well. The Bowers Museum of Cultural Art gives Santa Ana the distinction of being one of the few museums devoted to using art to promote intercultural understanding; Santa Ana‘s Bowers Museum has developed relationships with museums both national and abroad to maintain a globally cultural collection. The museum specializes in the art of the world’s indigenous people, maintaining one of the largest collections in the United States. The museum’s mission is the celebrate the cultures of the world through their art. Founded in 1936 thanks to a bequest from Charles and Ada Bowers, the museum is one of Orange County’s largest museums, and has been voted “The Best Museum in Orange County” by readers of the Orange County Register for the last 15 consecutive years.


A branch of the Bowers Museum in Santa Ana is the Kidseum, which offers a fun, hands-on approach to cultural experiences for children and their families. The Discovery Science Center at Santa Ana takes a similar approach to science and nature, offering fun programs such as the Eco Challenge that makes kids feel like superheroes or the true-to-life rocket-engine-launch experience.


Just a short drive away is Lyon Air Museum lets anyone in Santa Ana experience a piece of World War II history with tours of operational-condition Air Force planes from the period. Founded by Major General William Lyon, the museum features several World War II-era plans like the Boeing B-17 “Flying Fortress” and Douglas C-47 “Dakota.” It also has a collection of military jeeps, United States, German, and Japanese World War II-era motorycles, and historic World War II-era automobiles.


Of course, Santa Ana is not without any of the wide outdoors either. The Santa Ana Zoo at Prentice Park is a popular favorite year round. Santa Ana‘s Memorial Park is a relaxing park with all the family’s day out amenities – green grass, a great snack bar, and even a pool. Delhi Park puts Santa Ana as a locale in the novel Rain of Gold, and the Home and Garden Tours at Historic Floral Park and Historic French Park help raise money for Santa Ana student scholarships. Willowick Golf Course is the oldest public 18-hole golfing range in Orange County, and continues to be a successful, popular Santa Ana staple with PGA Class A staff.


Outdoor lovers are drawn to Santa Ana Mountains, which were named by members of Gaspar de Portola’s expedition, who made their camp in the mountains on the feast day of St. Anne. The mountains are home to several Registered California Historical Landmarks. These include an Indian Village Site nestled in Black Star Canyon, Flores Peak (named after the outlaw Juan Flores), the mining boomtowns of Carbondale and Silverado, and the Santa Rosa Plateau Ecological Reserve, which is home to the Moreno and Machado Adobes.


The Santa Ana River bicycle path runs through picturesque Santa Ana Canyon, running roughly parallel to California State Route 91. The Santa Ana River itself also provides opportunities for nature lovers. Its watershed includes parts of the Cleveland National Forest, San Bernardino National Forest, Angeles National Forest, Mount San Jacinto Sate Wilderness Area, Chino Hills State Park, and Lake Perris State Recreation Area.


Santa Ana residents also know the importance of keeping youth engaged to keep them, and Santa Ana at large, safe and prosperous. To that end, the City of Santa Ana has programs to keep kids and their families active. Whether it’s Youth Basketball, Aquatics, or Chess Club, there’s plenty of good, ongoing options. Santa Ana also offers Project PRIDE, or Parks and Recreation Inspires Dignity and Esteem. Visitors to Santa Ana will also notice several beautiful wall paintings and murals depicting local history throughout the city. These murals are painted by local artists and commissioned by the city.


Anyone looking to take a quick day trip for some extra fun has Southern California’s best in easy reach of Santa Ana. Nearby Huntington Beach, better known as “Surf City USA,” is known for its excellent, year-round surfing conditions, drawing pro-surfers from around the world. Just 10 miles south of Santa Ana is Newport Beach, offering miles of coastline, sunny marinas and lovely historic districts.


Santa Ana uses a mayor-council system of government. The council is elected by the citizens of Santa Ana, and then a mayor pro-tem is elected by council members from within the council. Santa Ana’s police department uses a community-oriented approach to policing that incorporates modern facilities and the latest technology.


Legal cases in Santa Ana are heard at either the Central Justice Center, Community Court, of Civil Complex Center. As the city’s population continues to grow, attorneys are always needed in Santa Ana. The City of Santa Ana works with law enforcement, attorneys, and private investigators to make sure that criminal and civil issues within the city are resolved.
