Who we work with

We work best with owners who want a long-term accounting partner

We're not the right fit for everyone, and that’s okay. Here’s a quick way to decide:
Chart icon

We're a good fit if you:

Run a service-based business with a team behind you
Are past the early survival stage and thinking about what's next
Want advice you can act on, not just numbers to file
Value clear communication and a relationship that goes beyond tax season
Are open to guidance and willing to do something with it
Think in years, not just quarters

We're not the right fit if you:

Only need tax compliance or last-minute filing
Are choosing an accountant based on price alone
Prefer a hands-off relationship with very little communication throughout the year
Are looking for tax loopholes
Prefer to hand things off and only hear from us during tax time
Aren't looking for ongoing advice

Why Red Alder

Better decisions start below the surface

Most accountants take care of compliance, but few actually help you figure out how the numbers can be used to make better decisions.

At Red Alder, we believe the numbers are only useful if you understand what they're telling you. Our job is to bring clarity to the decisions you're facing, steady the stress that comes with running a business, and be the honest, grounded voice in your corner when it matters most.

We're here to help you build something that lasts.

Testimonials

What our clients say about working with us

Before working with David and his team, my previous bookkeeper kept me in the dark. I never had timely financials, and business planning for my Tucson based small business was impossible. Firing her and hiring David and his team was a game changer. David, Chad, and Vanessa make sure I have timely, accurate financials every month, and I can also regularly run my own reports. Working with this team is like having a fractional CFO. They also help me with staff financial KPIs. That level of service (and the fact that they are also very fun people) made me choose them over other accounting firms we interviewed nationwide. If you want accurate books and timely, insightful financial guidance, this is your team!

President, Mulembo Law, PLLC

I’ve had an excellent experience working with David Oase, CPA. The level of professionalism, attention to detail, and commitment to providing quality service is outstanding. David takes the time to clearly explain financial matters, making complex topics easy to understand.

He is prompt in communication, knowledgeable about tax laws and accounting practices, and always goes above and beyond to ensure everything is handled accurately and efficiently. I truly appreciate his honesty, reliability, and personalized approach — it’s clear he cares about his clients’ success.

I highly recommend David Oase, CPA to anyone looking for a trustworthy and experienced accountant who delivers exceptional service every time.

Business Owner, Tucson

I had the pleasure of meeting David Oase for a consultation. He is extremely knowledgeable, polite, and professional. I was blown away by the level of customer service he provided. I’m so elated and thankful that my husband and I can be his clients!!

I had also spoken to a member of his team, Vanessa, when I intially scheduled my appointment. She was very informative, patient, and friendly.

(My husband and I are also going to use his firm for our tax returns!!)

Shelby Reifsteck

My husband and I have used David Oase’s services for the past two years and were very satisfied. The whole front office staff is pleasant and friendly. David has made our income tax return experience easy and efficient. He is highly knowledgeable and trustworthy. We will use this business again.
