Christopher Pfeiffer – Process Server
“I have used Mark exclusively for the past 17 years or so. I have used him both in the Metro area and on the North Coast in association with my Astoria office. Mark has found and served some of the most difficult people I have had to serve. He has found addresses on folks I thought would never be found. My suggestion would be to call Mark.” Posted on Oregon Trial Lawyers Association-2010

With Appreciation, P. Harris – Client
I know most of you probably already know about what a great process server Mark Ososke is. But I can’t help it, I just need to sing his praises again. We have a case were the defendant has turned out to be quite difficult to locate (don’t we all just hate that). Mark learned that the defendant had a date in traffic court, and figured he could have the guy served there. Unfortunately, it turned out the guy paid his fine without going to court – back to square one (sigh). Mark emailed me to report the missed chance and we discussed our deadline and budget. My lawyer was out on vacation, and I didn’t have an immediate answer as to budget. This was on Tuesday. Well, my lawyer got back yesterday, and today (Thursday) I replied to Mark with our budget. Mark shot right back that they had already found and served the guy – for half the budget! So – yet more kudos for Mark Ososke and his team!” Posted on OTLA-2012

Mark, I think you guys are doing great. You are knowledgeable, quick to answer questions, and have good turnaround time. I tell people about how great you guys are to work with whenever I get the opportunity. Thanks for your help on these. It is really helping to push for change in the industry. Tina Boggs – Precision Body & Paint Inc. Beaverton, OR
My claim for Vehicle Diminished Value compensation stalled due to inaction by Allstate Insurance. My DV consultant, Auto Damage Experts, Inc., referred me to PI Services to assist in filing a claim in Small Claims Court. The people at PI knew exactly what to do, had all the required filing forms and the PI staff was valuable in perfecting the filing. Their fee was reasonable and their process server was diligent, accomplishing service and getting the attention of the insured’s company. They followed up on my filing without prompting. All costs of the small claims filing were paid without dispute by Allstate. I would use them again in an instant and highly recommend them to anyone needing this specialized expertise. “Mark, I went onto your website to write a referral but couldn’t locate the link to do so. Please feel free to post this to your Facebook, Yelp or your site.” Nick, Portland, OR
Mark, I want to thank you for the great service you performed for me in finding my friend. Even though it had been 36 years since I’d seen her and she had moved several times, including out of state, you were able to find her quickly and I might add, economically. The rest of the story is that the reason she didn’t respond to your first attempt at contact was because at the time I was trying to find her she had experienced a significant health setback. She told me that your letter, follow up letters and her subsequent contact with me have had a positive impact on her recovery. I can’t thank you enough for finding her… and at just the right time. Your work may have actually saved a life here. Great job! I posted a couple of reviews for you on yelp and the YP pages. I can’t thank you enough and I will whole-heatedly recommend you and your services. B Hughes. – Client in TX Sent via Email and posted on Yelp & YP Pages
I spent over a year and a half working to try and recoup money that was owed to me by a previous room mate. After not getting any responses from him or any payments, i decided to file in small claims court. Once i got the forms to fill out, I felt even more confused and frustrated then I did before. That is when i Found PI services. They took care of everything, from filling out the forms and sending it into the court. They also served the defendant for me and kept me up to date as to everything that was going on. I am now working with them and the courts to reclaim my money. I couldn’t have done this without them and I felt that they were considerate and understood where i was coming from. I would refer them to anyone that is trying to get a small claims suit taken care of. They are the best! Will D. -Portland Found on Yelp.com
Mark, I just received the papers from you by mail, very professional, accurate documenting and very reasonable fee. It was really nice and good to know you. Hope to deal with you again if my friends or I need your help. Wish you all the best and thank you for your help and support. Moumen A. – Beaverton Client Sent via Email
I feel so much better, I can’t tell you how much you have helped my stress levels with this issue! I really truly appreciate your help and I will be using you for any future things and telling my friends about your great service. I was very determined to get this all done today, I imaged the serving process taking an eternity, I found out he had taken the day off today and would be home all day! I just had to get it to him it was my golden window of karma letting this be possible, and you and your company made it happen! Just thought it would be rewarding to know how much you really helped today! Take care, Ashley – Hillsboro Client Sent via Email

I wanted to leave a review on you website but I did not see where I could do it. I really want to say thank you Mark. You were so great during a difficult time. You were persistent in serving my husband with divorce papers and you did it very quickly. I really appreciate your patience and willingness to keep trying to get my husband to come to the door. Mark is really great and I would recommend his services to anyone. Thanks again, Tami in Beaverton Client sent via email.

I just wanted to thank you and PI Services for getting the garnishment completed & served. We have received our first payment and even though the balance due was a small amount, we are happy that this account is being cleared. Thank you again! Carol Taylor-J D L Development Inc.

1) An incredibly high degree of responsiveness and transparency to the status of how your ‘issue’ is progressing .
2) Earning your trust (key, in any high-stakes situation)
3) A willingness to go above and beyond.
4) Getting sh*t done.
I had PI Services perform work related to researching and serving somebody who had ‘skipped town’: I was extremely satisfied with my outcome (along with their approach) and would easily use them again. Mr. V.C., Client from Seattle, WA posted this on Yelp
Hello Mark, Thank you very much for getting Seterus to fill out as per the instructions. I greatly appreciate your help and assistance in this matter. You made my day. Sincerely, R. Hernandez, Florida May 2016
Thank you, Mark. Again, thank you for your help. It has resulted in an enormous revelation that helps considerably in my case and strategy for a fair and just resolution. It also resolves my confusion about my relationship with my husband. While the outcome is not pleasant, there is comfort in knowing the genesis of the problems and issues. Christine K. Lake Oswego

Greg Chrisman, Realtor, Caliber Realty Beaverton, OR 503-781-6514 firstname.lastname@example.org
We met Greg when we were looking at our first house 12 years ago. He was selling a house we were considering. After talking to him for a while I was impressed at how he was straightforward and did not attempt to sell a home that wasn’t a good fit. Later we had Greg show us many other houses, and we could tell he was thorough and was not going to let us get in a bad house or a bad deal. A few months later, he found our first house, and because of his quick work we got the house even as other offers were coming in. Five years later, it was time to move to a larger house. We called Greg, and he worked extremely hard for us. We found a house we wanted, and Greg’s diligence and hard work got us the house for a great deal. We would never have gotten our house without Greg. If you are buying or selling a home, you should call Greg. You really want someone you can trust and someone with the experience and dedication to get you the best deal. We are happy to say Greg is not just an incredible realtor; he has also turned out to be a friend of our family.
