Owner & Operator

Coverage Area​

Professional property management saves you time and money. Working with River Rock Property Management, owners can rest assured that we will do all we can to protect their property from today's highly regulated and often litigious environment. Today's investment properties are subject to municipal, state and federal laws and regulations and are assets that require sophisticated, experienced management. We are here to guide you through these laws and regulations to make sure your investment is protected. Additionally, we retain legal counsel to consult on complicated legal matters that may arise during the process.

Legal Expertise​

We understand that property owners have entrusted us with a valuable asset and major investment. Our goal is to maintain the property according to the highest achievable standards in accordance with a management plan established in consultation with the owner at the outset, followed by continued and regular communications.

High Standards

We take our cars in for an oil change every 3 months, shouldn’t someone check in on one of your biggest investments that often too? We think so, and that is why we offer our exclusive quarterly Wellness Check where we visit the property and report to you on the current condition. We have found that this pro-active approach helps better maintain the property and tenant relationships. Why wait until there is a problem to visit the property? You have the right to peace of mind, and we offer it four times a year at no additional charge.

Our Signature Wellness Checks

River Rock Property Management specializes in the physical and financial management of your investment - one house, condo or co-op at a time.

That means we simply don’t manage large apartment complexes, suburban homeowner associations or commercial shopping centers; instead we focus solely on you - the individual homeowner and/or investor.  Our entire portfolio consists of single family homes as well as condo or co-op units and multi-family buildings.  We keep our focus narrow, so we can focus on your property.

Michael Dillon


The founder of River Rock Management is

Michael Dillon. Michael is a licensed real estate

agent in Maryland, Virginia, and Washington, DC.

Michael started River Rock Management after too

many of his loyal real estate clients complained about

the sloppy property management services they were

receiving from the larger, impersonal property

management companies. Seeing a need, Michael

started River Rock to fill the void of a property

management company focused solely on the

management of homes and investments rather than

the large portfolio of commercial and apartment complexes.

Michael is a top-producing real estate agent at Slate Properties. An authority on the local real estate market, Michael has been quoted by The Washington Post, Washington Business Journal, Urban Turf Real Estate Blog and Fox 5 local news and has been featured on HGTV’s Designed to Sell.  Michael is also a member of the Greater Capitol Area Association of Realtor and the National Association of Realtors.

Michael also owns his own investment properties and knows first-hand the value of good management!

Interested in the fast pace and excitement of

Washington DC, Allison James relocated from

the business as the owner. She is committed to all

River Rock owners and tenants, and ensures everyone
