Exceptional Service -- William Sera Truly Goes Above and Beyond! We found Mr. William Sera through Google, and after reading so many positive reviews, we had a good feeling about reaching out to him. I'm so glad we trusted those reviews because our experience absolutely lived up to them. I'm writing this review in hopes that it helps the next person feel just as confident choosing William. William is not only extremely professional and knowledgeable, but also personable, patient, and genuinely supportive. Serving legal papers can be an overwhelming and stressful process, but William took the time to explain everything, guide us through what to expect, and make sure we had the proper receipts, invoicing, and documentation needed for court. What stood out most was the human side of his service. William understood that we were dealing with a difficult situation and helped make the process feel much more manageable. His guidance gave us a greater sense of confidence and control as we navigated the process of defending ourselves. William, thank you for your professionalism, kindness, patience, support and good humor. You made a difficult process so much smoother for our family. If you are reading reviews trying to decide whether to contact William, just as we once were, I can confidently say: give him a call. You will be in knowledgeable and caring hands. Bless you, William, and THANK YOU! You truly deserve every one of these five stars. read more

I don't usually leave reviews, but this is one of those times where it's absolutely deserved. If you're looking for a process server or private investigator in the San Gabriel Valley or West Covina area, I would honestly just go straight to William at My Investigative Services. I came across his business while trying to find someone reliable for process serving and possibly some investigative help, and based on past experiences, I wasn't expecting much. Usually it's slow responses, minimal effort, or you end up having to follow up constantly just to get basic updates. That wasn't the case here at all. From the very first interaction, William was professional, direct, and clearly knew what he was doing. You can tell he has real experience behind him, not just someone going through the motions. He understands how the legal process works, the importance of timing, and how to handle situations properly so things don't come back and cause problems later. What stood out the most to me was how responsive and on top of everything he was. I never had to chase him down for updates or wonder what was going on. He communicates clearly and follows through, which honestly is rare in this type of work. He also goes the extra mile. This wasn't a situation where someone makes one or two attempts and then moves on. He was persistent, strategic, and put in real effort to get the job done. You can tell he takes pride in what he does and actually cares about helping his clients, not just checking a box and moving on to the next job. On top of that, everything was handled professionally and ethically. That part matters a lot, especially when you're dealing with anything legal. I felt confident the entire time that everything was being done the right way. I've only worked with one other process server before, but even compared to that and even compared to services I've seen law firms use, William stands out. The difference in communication, effort, and overall effectiveness is very noticeable. If you need process serving, skip tracing, or private investigation services, especially in the San Gabriel Valley area, this is someone you want handling it. Bottom line, William is reliable, experienced, and worth every single cent. I wouldn't hesitate to use him again. read more

I can only give 5 stars, yet this business deserves 10. I was in a pinch and needed immediate process serving. I reached out to William and truly appreciated his prompt response, honest pricing, and the thorough information he provided.I called him around noon and by 5pm, he had successfully completed the task. Everything was well documented and promptly submitted electronically to the court clerk. William has a genuine passion for his work, and it shows. He helped put me at ease and shared valuable tips along the way. William turned out to be like a long-lost friend I didn't even know I had. I would definitely use his services again without hesitation and highly recommend him to everyone. read more

I asked for documents to be served to Opposing parties, it was done basically the same day, little did I expect Mr. William Sera filed the documents to LA Superior Court as well, it saved so much time and efforts, I would give 10 stars if there's 10 stars option, thank you so very much. read more

Just like the rest of the reviews say.. he's the REAL deal. William goes above and beyond for his clients. Professional, extremely skilled, and highly dependable. Thought the job would be impossible due to urgency and complexity, NOPE not for William. He went on a late night mission when he already had family plans. If there was a real life SUPERMAN, William is HIM. A huge plus is his personality, makes his clients feel like family right off the bat. read more

Excellent service. Very efficient and excellent communication throughout. Skip the Sheriff's Office, get this guy to serve your papers!

Services are outstanding. Professional and on-time. Highly recommend my investigative services.

My wife and I had a tough case against a homeless stalker. We originally went to the police, but they did very little to help. We met with Willie and immediately felt far more confident that we would be able to find and serve a restraining order. William faced a tight deadline and a challenge to locate the homeless stalker with very little information. William was methodical and persistent in his search, all while keeping a record for our case of every attempt made as proof of due diligence. Eventually we got a call with the good news that Willie was able to locate and serve, which led to us winning our case in court. We would highly recommend William's services to anybody who is looking for a P.I. at an affordable price. read more

The work ethic and professionalism speaks volumes. We received great advice and guidance. You will not be disappointed. Service was requested and the was successful the first attempt later that same day. You couldn't find better service at a better price. read more

On March 13th, sod was installed at my home and, within weeks, rapid deterioration began quickly.  After many stall tactics, texts and promises to fix the problem, the landscaper decided to walk away with $2600 of my money. I was anxious, unhappy, in disbelief and resentful. The first agency I contacted could not locate the landscaper based on the only information I could provide - the first name and cell phone number! I know. I lucked upon a company called MY INVESTIGATIVE SERVICES and spoke with WILLIAM SERA. Within literally minutes, WILLIAM SERA had found the guy; provided a full name and physical description; an email/residential address and even past employment. WILLIAM SERA of MY INVESTIGATIVE SERVICES issued a REIMBURSEMENT DEMAND LETTER to the landscaper and within two weeks the sod was removed and my money including the cost of the search reimbursed in full. Aside from WILLIAM SERA'S talent for finding people quickly; he is jovial, kind, calming, professional and determined. What more do you need? read more

William was very kind, knowledgeable and professional. I needed to serve someone the day of and he got it done. I was told it couldn't happen or given a window of 2 days but William got it done. Ask him to tell you stories. LOL FYI he's a retired cop read more

I had the pleasure of working with William from out of State. He answered my call and was very professional, courteous and very responsive with the process. You will not get a better service from anywhere else. He helped us from beginning to end in making sure a restraining order was served, abided by and was very supportive. He kept me informed during the whole process and treated us like family. You will not be disappointed with his services. Five stars all the way! read more

I've just completed having legal documents served. I didn't know where to turn for this service and was told that the Sheriff's Dept would serve, although it could take a long time. I checked Yelp for Doc service and found My Investigative Services. Steve is awesome. He's timely, honest, and diligent. His follow up and follow-through is above par. I highly recommend My Investigative Services. read more

I needed a process server for a task to be performed in Anaheim and was extremely fortunate to come across My Investigative Services. William was extremely professional in all of his dealings. He explained the process to me and made it easy for me to accomplish my objective. He was also punctual and communicative at every stage. Based upon my experience I can wholeheartedly and without any reservation recommend William and My Investigative Services. William is a real gentleman and I thank him for his exceptional service! read more

I can not thank Willie enough for his services. When I say I needed help, he was definitely my savior. I'm dealing with a sensitive situation and live in the Bay area, so trying to have someone served near the West Covina area has been challenging for me. He listened to my situation and concerns before taking on my case. I appreciate his professional approach, wise words of advise and gentle reassurances at times when I felt stressed. There was an open line of communication and an update for each task he did on my behalf. Hiring Willie has been the greatest thing I've done for this situation, his fee is reasonable and my case was completed in a few days tops! Had I done this on my own, I feel like it would have been weeks or a month. I would definitely hire Willie again for future services and highly recommend My Investigative Services for anyone seeking excellent quality services. Trust when I say, Willie will get it done! Thank you again for all your hard work, your work ethic is grately appreciated. read more

The service was good, but there was a mistake. When they completed the paperwork, they did not review the documents I have given them and misspelled the name on the document, which I have provided for them correctly. I now have to go and resubmit the documents myself due to a misspelling which was made and their end and not mine. Wish I would have caught the error right away..... now I am left to have to do extra work due to this error. read more

William is very professional and knowledgeable as a process server for my legal document. I am very happy for all he promised and has done the service promptly. He even showed me a standing order of the court to be included in the claim document. I like his case manager software with links to store and keep up my legal case detailed information such as the follow ups and the detailed description of the person whom he contacted. He is so organized in handling business. I have referred him to a group of people I connected! May God continuously bless his business to be very successful! read more

BEST! EVER -PI HALL OF FAME - SUPER STAR - HUMANITARIAN I paid 3 agencies & made no progress in serving divorce summons that required personal service. On the day that I found William Sera my documents had been passed around by three other server's. Intimidation was proving effective. I was running out of options and money. William did not hesitate to accept the job. The stress the other server's put me through was overwhelming. William endured the state of uncertainty I was in. Most men would have walked away out of shear frustration. He explain the time frames and options if personal services was not possible, which no one else did. That changed everything.... Because of time wasted and I mean wasted with the other agencies I had to refile the entire case. It wasn't just time wasted it was costing what I can't afford. William guaranteed resolution to the personal service that everyone else took my money and ran. Now I was in a much better, calmer, secure place. I had understanding which made all the difference. Filing for my divorce was already stressful. I needed help and I was now getting the help. He said "TRUST" me and I was ready to go through the next few weeks getting it done- with understanding and a guarantee. 5 minutes later and William calls me, it was done. The opportunity had presented itself and just like a SUPER STAR it was done. MY HERO!!!!!!!!!!!!!! What more can I say........... So grateful and I would most definitely recommend William Sera for all your investigative, document service, court related matters. You name it. I'm sure if your in a legal bind of some sort William can probably provide services not listed on the website. Call him and get that guaranteed professional job done. Don't was time and money with uncertainty. read more

William is extremely knowledgeable, has decades of experience, highly skilled, insightful, a true professional, diligent in his duties, and his integrity is above reproach. William stayed in contact with me throughout the entire process. I would definitely recommend William to others and will be utilizing his services again and again in the future. I am thoroughly impressed on how quickly he worked to get this done. Respondent had been evading for weeks, but William found a way and got him served in a flash. He knows what he's doing and we are so glad we found him! read more

William is truly the best! I had legal documents I needed to get served to a difficult party within 24 hours and everyone else I spoke with couldn't guarantee but were quick to give me a price. He was confident he could do the job when I spoke to him in the beginning and he delivered going above and beyond. I would recommend him to anyone! read more

We used this company for process server paperwork. Very professional and thorough. Great attention to detail and video of everything he did for us. Thank you William read more

Excellent service! I would recommend William to anyone who needs a professional process server. I was working with another process server company and all he did was give me the run around.

William will minimize your stress. Very professional. read more

William is just phenomenal. I called several different places before and got high quotes, poor services, and pessimistic responses. As soon as I spoke to Will though, he went above and beyond to get our work done correctly right away. He's fair priced, very professional, and gets the job done. HIGHLY RECOMMEND read more

William gets results fast! I contacted William at 11 am by 2 PM that same day, he had served the court papers! I had been attempting to serve these papers for the past two weeks wasting my time and stressing. I had no address only a phone number. William ran a skip and found all current information. I wasted my time and money attempting to run background checks by myself with companies like Intelius, been verified, white pages, and check people. Don't waste your time and money William makes this process smooth and efficient everything was completed over the phone and email. He is attentive, personable, communicative, and great customer service! Serving someone is already a stressful situation he takes the stress out of it. I would never attempt to inconvenience family or friends again with the favor of serving someone when there is a company like My Investigative Services that does things efficient and fast. They even record the serving and send you a video! That is just above and beyond I am extremely impressed and satisfied and would definitely recommend their services to my family and friends. Thank you, William, for all your help. read more

If I could give ten stars I would!!! Amidst the covid crisis my ex and I were disagreeing about custody... phone call after phone call of robots, Will was the first person in a month to speak to me like a human being! Very professional talking me through the steps and his methods as a process server and for the first time in months I feel confident about the work done on my behalf. Highly recommended for whatever you need! read more

I needed to serve a business and a person. Contacted My Investigative Services and William contacted me back. Expressed that I've never served before and he assured me it'll be no problem.

Was a pleasure working with him, would definitely recommend. read more
