Local healthcare landscape in Mercer Island
The City of Mercer Island's draft comprehensive plan, a City Council public review draft dated October 1, 2024, says Mercer Island prides itself on being a residential community, served by a small Town Center and two other commercial zones. The draft describes the Town Center as a 76-acre bowl-shaped area and states that the most densely developed neighborhoods are found on the Island's north end, naming First Hill among them. One land use designation in the draft says healthcare uses, schools and places of worship are also generally supported. The draft names Luther Burbank Park, Aubrey Davis Park above the Interstate 90 tunnel, and land set aside in Pioneer Park. Its economic development element describes a south end commercial area zoned for small scale, neighborhood-oriented business. Separately, Overlake Medical Center & Clinics, a nonprofit, independently operated regional health system, lists an address at 1035 116th Ave NE, Bellevue, and its locations page groups its sites by city: Bellevue, Issaquah, Kirkland, Newcastle, Redmond, Sammamish and Lynnwood.

What we'd prioritize for a Mercer Island practice
Chosen by fixed rules from the figures above.
Room to stand out for plastic surgeons
No NPI-registered plastic surgeons list a practice address in Mercer Island (nationally there is one for every 58,824 residents). Fewer local competitors in search for a plastic surgeon. See our marketing for plastic surgeons.
Lead with elective and cash-pay services
Mercer Island has a median household income of $219,069; the US median is $80,734. Elective work earns its own pages and budget, with Google and Facebook ads.
Detailed treatment pages first
Among Mercer Island residents 25 and older, 81.5% hold a bachelor's degree or higher (US 35.7%). We would write detailed treatment pages first and build the SEO work on them.
Reviews and your Google Business Profile first
Mercer Island has one NPI-registered dentist for every 978 residents, against one per 1,340 nationally. We would start with the Google Business Profile and review management.

What Our Clients Say
I’ve had a great experience working with Medi-Edge. They helped design and build our website and have also been handling our SEO and online advertising. I’ve been very satisfied with both the quality of their work and the results so far. Kellen, the owner, has been especially great to work with. He’s been very responsive, helpful, and personally involved whenever I’ve had questions or needed assistance. It’s been nice working with a company where the owner is accessible and genuinely cares about making sure you’re happy with the service. Overall, the entire team has been easy to work with and understands the needs of a dental practice. I would definitely recommend Medi-Edge to other dental /medical practices looking for help with their website, SEO, and digital marketing.
As a fairly new business going into our 5th year I can say this company truly walks it like they talk it. There are many companies promising new companies the stars and the moon and as a new business you have to take risks and invest. If your looking stop and sign up with this company, constant communication, monthly updates, and can always reach them whenever you need an update to your website or help with your google business. I'm glad we found this gem and we always keep it real at IMED DTLA so if your a new business this is your sign. Not only are the prices reasonable the work is amazing and efficient!
I’ve had a great experience with media-edge marketing Kellen and his team are very responsive and always get to my requests in a timely manner. They are also kind, flexible and seem to care about my business and success which is important to me as a new small business owner. Looking forward to growing with them!
