Ken and his team (Alice, Lindsay, etc.) are all excellent. I've been working with them for my business and personal taxes and utilizing bookkeeping services for years. II have had nothing but a positive experience with Ken's office. I have and will continue to recommend Ken and team to clients, family and friends.

Does it really take 2 years to review a tax return? does it really take 2 months to review corrections and omissions the I pointed out on a current year tax return? and because of their delays- I had to pay the penalties! and was expected to pay for the preparations in full. I had to sign every Power of attorney twice because the "didnt go through". Really? every time? Every request was channeled to the assistant, Alice, and disappeared.

I was told "we called you several times" - which they did not. I was blamed with "you didnt sign the XXXX form" without explaining why I should or what it is. In short - UNRELIABLE UNTIMELY UNPROFESSIONAL DONT GO THERE.

Disorganized and did not complete taxes on time! Never returned multiple phone calls to his office when we called to check on how things were going a few weeks after dropping off tax information. Thoroughly disappointed and will NOT return. I strongly do NOT recommend this practice.
