Of course we’re always going to tell you how wonderful we are! But we realize that’s just not good enough. That’s why we’ve assembled a number of comments from our clients, which should give you a real insight into how we work, how we treat our clients, what we do for them (day in, day out) and ultimately how we support them through the development of their owner-managed businesses…

“High Degree of Fiduciary Ethics”

Having recently purchased our first home, my wife and I could have easily been overwhelmed by the entire process, which is why being able to work a long side Mark Olson was such a wonderful experience. Mark was able to demystify the ins and outs of the real estate market by walking us through the process every step of the way. From placing an offer, to helping us with escrow and making sure our inspections ran as smoothly as possible, we could not have done it without Mark’s passion and experience. Most of all we appreciated Mark’s honesty, which I find a very rare quality when working with agents. He was very transparent with us from the get go when communicating with the sellers, which greatly helped reduce any road blocks that came our way. Thanks to Mark we were able to not only close ahead of schedule but end up in our dream home! All of this is why I have to give Mark an outstanding review and recommendation to anyone looking to buy and sell their next home!

Mark is very personable, delivers creative solutions to problems and provides accurate work at great value and always met our deadlines. I would have no hesitation recommending Mark for assignments and I plan to use his services in the future.

We brought Mark on board at a difficult time for our organization. We were without a CFO or a Controller. Mark provided mature, solid guidance as we stabilized and re-organized our accounting and finance department.

I had the pleasure to work with Mark and to report to Mark at DriveCam. Mark was a good leader, he had solid leadership skills and was able to bring the accounting department together to form a cohesive team. I would highly recommend Mark for any of your Accounting and Finance needs.

I worked with Mark while at DriveCam on a cross-functional basis for both commissions and deferred revenue accounting matters. I was impressed with his flexibility, knowledge and enthusiasm in dealing with both of these critical and complex matters for DriveCam. I knew that Mark was involved in restating revenue recognition in accordance with SOP 97-2 and coordinating with EY on the audit, so I sought Marks input while developing potential customer hierarchies for the Salesforce CRM project. Marks insight was crucial due to multiple shipping points and site go live dates.
