So sphiscated accounting systems I must say. For what? Never saw an irs payable in any return they asked me to prepare although I’m no licensed accountant. No names no whistle just a honest google review. Makes me wonder what an accountant does, cooking books or AICPA reporting them. No mark up in my basis. The roc building is beyond comprehension though, they even do SNL up or down stairs never got to see a show so I don’t know

Deloitte completely failed implementation of Army IgnitEd, which led to thousands of service members paying out of pocket for education expenses. The circus that we watched unfold leaves me with zero confidence in the services that this firm provides.

My organization has been working with Trueline for several years now and we have always been extremely happy with the partnership we've built and the work they've done for us at Good Will - Hinckley. Our rep, Erica, is always responsive to requests (usually turning things around in 24 hours or less) and she's easy to work with. I would highly recommend Trueline for any organization's marketing needs.
Show moreSusanna Suba's Review Sourced from Google
The clients needs were either not communicated properly to the staffing agency or the agency didn't find it important to disclose ahead of time. Complete mismatch about my abilities vs what the client needs. Basically a 10+ years experience senior litigation paralegal was recruited for a legal secretary position for transactional matters. Majority of my tasks included filing emails into a case management system, finding meeting dates reading through email chains and calendaring those (barely any litigation deadlines) but under strict supervision of how much time is spent on an email.

Dr Oullette and his team (Cyndi, Mandy, Samantha, lab guys) have changed my life for the better. I used to be scared of the dentist, and while procedures may be daunting, at this office I feel completely secure, cared for, and calm. Their customer service and work ethic is impeccable, and I would never dream of a dentist office with such a nice vibe! If you are like I was, avoiding the dentist, this is your place. I urge you to take the first step and schedule an introductory conversation/review with Dr Oullette -it's a game changer.

I'm beyond grateful for Mike and his team. From the very beginning, I was treated like family. They were quick to respond to my emails, phone calls, and texts, and I couldn't have asked for more professionalism or expertise.I am considering buying a home this year and Mike was in constant contact with my lender to come up with the best strategy for me. He meticulously reviewed every detail of my taxes, and ended up switching gears and saving me thousands more than I anticipated. I am truly impressed!Working with Mike felt like collaborating with a trusted friend, and he made the entire experience, with something as dreaded as taxes, enjoyable. I felt valued and supported every step of the way.If you're looking for someone who truly has your best interest at heart and will go the extra mile to make sure you are filing in a way that is the most beneficial for you, you won't regret reaching out to Reeder CPA Group.Thank you so much for the excellent service and all the extra money!

Pegas is a hidden gem who I was lucky enough to be referred to over 5 years ago. I have contracted them for all types of marketing and web development services over the years including some specialized services I’ve yet to find anywhere else.. they can do it all from making apps and websites to full fledged enterprise level marketing campaigns involving paid ads, email, sms and more. I have a great working relationship with the CEO, Will and their lead developer, Richard. They are the real deal and don’t outsource oversees.. I get to work directly with the team and utilize them as an extension of my business. As a web expert myself, I fully appreciate what they offer and would recommend them for anything digital related without hesitation. Thanks guys!

We brought them a $25k starter project and they wouldn’t even give us a proposal. They only want large government contracts that should probably be done with some other company who will do so more efficiently, and save all of our tax dollars. The representative was nonresponsive and offputting. Snobby.
