Accounting Review from Dmitrii Legetskii
This company helped us set up our accounting system from beginning to end. I am a serial entrepreneur with experience working with many different accounting groups and this one has been the most responsive overall. They have helped us with registering the business, putting together payroll, and getting our quarterly tax returns filed. They have been also very helpful with giving personal tax advice. I would recommend them to any other friends and especially other business owners.

Lizanne Lachat's Review Sourced from Google
I applied to a job listed on Indeed.com through Scion Staffing. I'd never worked with a recruiter before, other than for temp positions. Sarah was an absolute pleasure to work with, so professional and down to earth. She helped guide me through the interview and decision-making process, and followed up each step of the way. She was supportive and non-aggressive. I highly recommend Scion Staffing and would definitely work with them again.

My experience with Scion staffing was phenomenal. My recruiter took the time to get to know me as a person, learn my short term and long term goals prior to referring any possible positions for me. Once that position was referred, she was with me through every step of the interview process. She anticipated questions that may be asked and how best to prepare for them. Really, this was a 5/5 star experience all the way!

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.

I had an excellent experience with BPM. I recently switched auditors and BPM was able to identify errors and streamline some business processes for our finance team. I had such a good experience working with BPM's auditors that I decided to add them as our Tax CPA's as well. Great service and very knowledgeable staff with many from Big 4. Good value too with low fees vs Big 4.

Kirsten AD's Review Sourced from Google
I've enjoyed working with Artisan both on internal projects and being placed with clients through them. While they don't see the same number of roles as some of the bigger companies, they do tend to get jobs with higher pay rates than some of the other staffing agencies - and definitely advocate for the talent when it comes to dealing with clients. I would definitely recommend getting in touch if you're looking for work in a digital/creative role.

I worked for Artisan as a Contract Copywriter for more than three years. The team did an excellent job finding me a contract with an outstanding company. In addition to a great placement, Artisan provided me with very good benefits, including 401K and some paid time off, which is unusual in the industry. I highly recommend Artisan to anyone who is looking for contract work.

In a world of agencies that are mostly out for a quick buck, they build relationships on both the client and talent side. It is a refreshing change of pace to see such integrity. They are fair and honest people that I worked with for years. If you are looking for talent, or have a talent, I can not recommend them more.
