Resolve disputes without the courtroom.

Mediation services are offered as a standalone practice, independent of real estate representation. With a background in M&A due diligence, healthcare operations, and transaction advisory, disputes that involve real property, business interests, or commercial relationships are handled with genuine subject-matter fluency — not just process.

Most Common

Real Estate Disputes

Boundary and easement conflicts, landlord-tenant disputes, co-ownership disagreements, broker commission disputes, and contract interpretation issues. Ideal for parties who want a documented resolution without litigation costs.

Request mediation →

Business & Commercial

Business Transaction Disputes

Partnership disagreements, business sale conflicts, lease disputes, vendor and contractor disputes, and M&A transaction disagreements. Particularly well-suited for lower middle market disputes where the cost of litigation is disproportionate to the matter.

Request mediation →

Family & Estate

Estate & Probate Disputes

Family disagreements over inherited property, trust administration conflicts, and disputes arising during the sale of estate assets. Handled with care for the relationships involved, not just the transaction.

How It Works

The Process

  • 1.Initial consultation to understand the dispute and confirm mediation is appropriate
  • 2.Each party submits a brief written summary of their position and desired outcome
  • 3.Structured mediation session — in person or via video — facilitated by a neutral mediator
  • 4.Written settlement agreement drafted and signed by all parties if resolution is reached

Important: Mediation services are offered independently of real estate brokerage services. Sierra does not serve simultaneously as mediator and real estate agent in the same matter. Mediation is not legal advice, and parties are encouraged to consult independent legal counsel.

Who We Serve

Built for the people who need it most.

  • Estate sale referrals and trusted vendor network
  • Clear communication with multiple family members
02

Parties in a Dispute

For individuals, business owners, and families who are in a real estate, business, or commercial dispute and want a structured, cost-effective path to resolution — without litigation. Mediation works best when both parties are willing to reach an agreement and want a neutral facilitator with actual subject-matter knowledge.

  • Real estate boundary, contract, and landlord-tenant disputes
  • Business sale and partnership disagreements
  • Estate and probate property conflicts
  • Commercial lease and vendor disputes

What people want to know.

Timing is the most critical element. We coordinate with the assisted living facility's placement timeline so the home sale closes when you need it to. We also connect families with estate sale professionals for personal property, and handle all listing and communication so families can focus on the transition itself.
Depending on the package, a report can include comparable market analysis, value estimate, permit and lien history, zoning and land use review, rental market comparables, neighborhood and submarket summary, and a written advisory memo with risk flags. All reports are delivered as structured documents suitable for investor review or legal proceedings.
For business owners preparing to go to market, we analyze real property assets involved in the transaction — including market valuation, zoning and use review, lease assignment considerations, and location market conditions. We produce written advisory memos formatted to work alongside M&A documentation, suitable for sharing with your broker, attorney, or buyer's team.
We are based in Alta Loma (Rancho Cucamonga) and cover the broader Inland Empire — including Upland, Ontario, Fontana, Chino, Chino Hills, Eastvale, and the High Desert (Hesperia, Victorville) for investment transactions.
Yes. Due diligence packages are available as standalone services — no listing or purchase agreement required. Many investors use them before making an offer, and business owners order them to understand their real property position before engaging a business broker.
Mediation works well for real estate disputes (boundary issues, landlord-tenant conflicts, contract disagreements), business transaction disputes (partnership conflicts, business sale disagreements, lease issues), and estate or probate property conflicts. It is most effective when both parties are willing to reach a resolution and want to avoid the time and cost of litigation. Mediation is not appropriate for every situation — an initial consultation will help determine if it's the right fit.
No. A mediator is a neutral facilitator — not an attorney and not a representative for either party. Mediation is not legal advice. Parties are always encouraged to consult independent legal counsel before and after mediation. Mediation services here are offered completely separately from real estate brokerage services.

Let's talk about your situation.

Every inquiry is handled personally. Whether you're a family navigating a senior transition, a business owner preparing for a sale, an investor evaluating a deal, or a party seeking mediation — reach out and we'll respond within one business day.
