Local healthcare landscape in SeaTac
The City of SeaTac incorporated on February 28, 1990, and is located between Seattle and Tacoma, with Seattle-Tacoma International Airport located entirely within the city. Its land use plan names City Center, the South 154th Street Station Area and the Angle Lake Station Area as the city's three urban villages. The plan's background report describes McMicken Heights and Bow Lake as neighborhoods in the eastern portion of the city, refers to an Angle Lake neighborhood, and places Riverton Heights in the section of the city north of SR 518. Valley Medical Center & Clinics, founded in 1947 and organized as a public hospital district, describes its acute care hospital as located in Renton.

What we'd prioritize for a SeaTac practice
Chosen by fixed rules from the figures above.
Room to stand out for dermatologists
None of the NPI-registered dermatologists list a practice address in SeaTac; nationally there is one for every 17,857 residents. Fewer local competitors in search for a dermatologist. See our marketing for dermatologists.
Get into local search early
Counting all seven provider groups on this page, SeaTac has 4.0 NPI-registered providers per 10,000 residents; the US has 22.3. Dermatologists are the thinnest group, with none matched inside the city. Fewer competitors to outrank: we would start with local SEO.
Make the practice easy to find for new residents
SeaTac grew by 3,130 residents (+10.0%) between April 2020 and July 2025. With that many new residents, we would start with maps and directory listings.
Set the practice apart from nearby dental offices
Dentist offices make up 27.8% of the private-sector ambulatory health care establishments in King County, against 18.5% nationally. Here a dental practice should be known for one thing; see our dental practice marketing.

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!
