Bonnie Kwok Professional Optometry Corporation
I run a busy optometric practice, and Achen Henderson looks after my financials, while I stay focused on looking after my patients. After a busy day seeing and managing patients, it is so nice to come home to spend time with my young family instead of poring over payroll and bookkeeping. My staff get paid on time, and properly, which keeps them happy, and my books are managed by a professional who knows the ins and outs of my business.

Achen Henderson is extremely organized and the future of business consulting, utilizing well-developed mobile apps to manage payroll, time-sheets, bookkeeping, and documents. They are responsive and thoroughly understand the needs of young entrepreneurs. It is so refreshing to have someone who can guide me in making decisions that are in my business’ best interests.

Achen Henderson has certainly helped me, enlightened me, in terms of where we’re at… They get it; they understand your troubles and adversities. They are committed to working with you and helping you find solutions – they take a vested interest, and they care. They have helped me focus my thoughts and focus on where I want to take the company.

The overall leadership skills that I’ve developed through working with Achen Henderson has certainly put the company in a much better place. We’ve come such a long way, in just six months, we’ve turned the whole culture and leadership environment around at Element.


If you’re thinking about switching – do it.

Joseph M. Toole, President – Toole Group

After our accountant of forty plus years retired, we tried several small and large accountants and found Clayton and George. They understand our family and our various business’ accounting situations. I am totally and delighted with their professional and knowledgeable services. They have given me peace of mind.

Honestly over the years I could write a book on the exceptionally outstanding services your team has provided for my parents, siblings, children and numerous companies. The succession from our old accountant as he had passed to the moving to your new firm truly saved me from a break down or worse. Words can not define how you helped us all. The numbers and savings speak for how Blessed we are to be your client (family).


Thank You

Aaron Bunting, CFO – Stream Asset Financial Management

I switched to Achen Henderson because my corporate structure has become increasingly complex, and I am incredibly confident in their technical advice and ability to handle my complex accounting and tax needs. I appreciate the fact that the team of ac is heavily invested in being a technological leader in their field but with client service as a core philosophy along with their modern service delivery.

Sharon Guay - Bow River Exteriors Ltd.

Well, we can honestly say your team is fantastic, we have worked with other offices over the past 40 years, and Achen Henderson is the friendliest, most efficient and easiest to work with. We will recommend your office to friends, family, and business associates for those very reasons.

Bruce A. Weaver, President – JAN-PRO Cleaning Systems

Achen Henderson has brought the finances of our company to another level. The support and insight gained from Clayton and his team have allowed us to set up our corporate structure in the most efficient manner possible. This is a massive improvement from our last provider—we are now proactive towards government and tax policy rather than reactive. It’s definitely worth an hour of your time to sit down with Achen Henderson.

Donna Dunn, Owner – Chicken on the Way

Since we began working with Achen Henderson, it’s been a tremendous relief to know our accounting and tax issues will always be thoroughly addressed and our questions answered. As a small business, we don’t need a full-time in-house accounting department, and we certainly couldn’t afford one either; with Achen Henderson, we have ready access to the expertise, professionalism and continuity we require.

Cindy Cleveland

My first encounter with Clayton was very encouraging. I felt ill-equipped to deal with my father’s estate and it’s many complications. Poor record-keeping on Dad’s part was overwhelming for me. I brought in Rubbermaid totes full of papers that Clayton made short work of. We’ve since had a 4-year professional relationship and I continue to rely on him to help me sort out the estate taxes and profit and losses. Recently I was again overwhelmed by pending disbursements and within moments my mind was put at ease and paperwork generated to satisfy beneficiaries. Thank you, Clayton! 

Ann Koelln

Having Achen Henderson Professional Accountants take care of my accounting needs was painless for me.  The process was uncomplicated, and the people dealing with my accounting needs are kind, supportive and knowledgeable. A very positive experience. Thank you to the Achen Henderson team.

Why do I keep going back? Several reasons: Clayton Achen is very knowledgeable, and for that reason, I trust that he is doing the very best to complete my income tax promptly, and thoroughly. I am very comfortable asking him questions, to which he responds promptly and in a way that I can understand. He even sends videos with instructions that are easy to understand and do! The Achen Henderson team are patient, professional, and are always available to answer my questions. 


Thank you very much!

Achen Henderson has looked after my accounting since I have opened my doors. They have striven to be ahead of the curve when it comes to accounting (hard, right?) increasing their efficiency, thus helping my business run more efficient and profitable. They have done a wonderful job of streamlining my business and would recommend them to any company big or small.

Brad Stone – Remax Realty

I have thanked my cousin multiple times for referring me to Achen Henderson. The level of service is first class, and the convenience of dealing with such a tech-savvy firm is priceless. I get excited when someone tells me they are looking for an accountant because I have the best referral to provide!

Nick Bryanskiy, J.D., LL.M – Bryanskiy Law, Barristers & Solicitors

I was introduced to Achen Henderson LLP at a networking meeting in Calgary. This turned out to be the best referral of 2014. Clayton is fantastic, and I would recommend him to anyone who wants top quality, excellent customer service and reasonable rates (a rare find in Calgary’s busy and not always helpful market). Moreover, Clayton went out of his way to provide meaningful and focused advice to some of my clients. It did not go unnoticed. We are looking forward to working with Achen Henderson in the future.

Roy Knive, President - The Knive Group Ltd.

Very responsive with clear instructions and processes to follow. Very impressed with AH move to ‘paperless’ capabilities. Their systems work very well and include helpful videos etc. to support the online processes.

It was great. George and Wallace were excellent and responded quickly when my corporate file was picked up. Wallace found bookkeeping mistakes and answered all my questions. I feel confident and reassured in having Achen Henderson prepare my corporate year-end, file my taxes and consult me on my business. We even did this all online during Covid. Thanks!

Great attention by Clayton. Quick completion when our information was complete.

The whole process was fast and efficient. The time from completing the engagement letter all the way to receiving confirmation of the filing was extremely short.

Wallace was very prompt in his responses to my inquiries and his service minded approach was very appreciated.

Eric Shaw

We’ve used Achen Henderson for our last two personal filings and they we’re able to recover a significant amount of money on past filings on our behalf. Great team, great service and we couldn’t be happier.

Sid Been

I like it that everything was done on line – no need to visit the office to drop of receipts, pick up papers or pay the bill. Although, if I needed to I could visit the office to discuss issues in person.

The tax review was done quickly and I was pleased with the accountants knowledge and speedy review.

Shelley Miller

I have worked with Clayton, George & the team for several years now. My questions are answered quickly and my information and returns are completed within days of submission. I also learn something new every year working with them. I will continue to use their services and recommend others to do so as well.

Scott Ramsay

Great service as always. Easy process which saves me time! Upload documents, complete check list and that’s essentially all I need to do! Thanks again! See you next year!

Derek Goodbrand

Exceptional personalized service year after year. Always quick responses to my questions

The Achen Henderson team has been great over the years. They’ve done great work on our returns which involve some advanced investment strategies and helped with a complex CRA audit.

Eric Plante

Wallace was amazing, very quick and prompt. The process was very simple, and the initial questionnaire helps to collect all the required documents.

Kelly and Sandra Toole

In these times, for personnel taxes. You handled it in a timely manor. Communications were good. Even I could follow your directions eventually.

Bobby Lynn Bolig

They always provide excellent service and they are very efficient. I highly recommend Achen Henderson.

Patricia Bietz

Achen Henderson was very organized and quick to respond to my questions during tax season and were able to communicate with my brokerage to simplify the the whole process. I loved that I could sign my tax papers and pay my fees all on line. It was a simple process for me to follow.

Wendy Peters

Things were processed very quickly. I brought my tax slips in for scanning which I really appreciated as it’s difficult to do when you’re using a phone or iPad as a scanner. Everyone I’ve dealt with at your firm has been very helpful.

B. C.

Great experience with Wallace! He thoughtfully answered all of my questions and helped us understand the sections we needed some guidance on. Great experience and a very fair rate. We will be back next year!
