Senior Attorneys. Personal Attention.
There's no shortage of attorneys in Denver. Here's why clients choose Summit Law Group — and refer us to everyone they know.
Senior Attorney on Every Case
You hired a senior attorney. You'll work with a senior attorney — not handed off to a paralegal or first-year associate.
Free Initial Consultation
Every case starts with a confidential consultation at no cost. We'll give you an honest assessment — even if it means referring you elsewhere.
No-Fee PI Cases
Personal injury cases are handled on contingency. We don't get paid unless you do. No upfront costs, no risk to you.
Same-Day Return Calls
We commit to returning all client calls within the same business day. You should never wonder where your case stands.
Colorado-Only Practice
We practice exclusively in Colorado — which means deep knowledge of Colorado courts, judges, and opposing counsel.
25 Years of Local Relationships
Two and a half decades of building relationships with Colorado courts, mediators, and the opposing attorneys who appear regularly in our cases.
What Our Clients Say
Over 2,800 cases handled. Real clients, real results.
After my car accident, I was overwhelmed — dealing with the insurance company, medical bills, and missing work. Michael Sullivan took over everything. Eighteen months later, we settled for $280,000 — three times what the insurance company offered before I called Summit. I can't recommend this firm highly enough.
We've used Summit Law Group for all our business legal work — formation, vendor contracts, an employment dispute, and a commercial lease. Every matter has been handled thoroughly and efficiently. Michael gives us straight talk, not legal double-speak. They're our firm for life.
I was dreading the estate planning process — it felt overwhelming and morbid. Michael made it clear, organized, and even reassuring. My entire plan was done in three meetings. For the first time, I know my family is protected. Worth every penny.

25 Years of Senior-Level Attention
Michael J. Sullivan founded Summit Law Group in 1998 with a simple but uncommon commitment: every client would have direct access to a senior attorney — not a parade of associates and paralegals — throughout their case.
That commitment has shaped the firm's culture for over 25 years. Our attorneys have handled more than 2,800 cases across practice areas as diverse as multi-vehicle accident reconstructions and complex business acquisitions. The breadth of our experience makes us better at each individual practice.
