Diaz-Freed, Megan DDS

Dentists in older Sioux Falls neighborhoods often feel like relics—small storefronts tucked between bungalows, where the hum of a drill blends with the occasional freight train. Megan DDS at Diaz-Freed fits that quiet rhythm, operating from a one-story building on 1709 E 10th St, just east of downtown. The area still has that mid-century grid feel, with sidewalks that slope gently toward the Big Sioux River half a mile away.

They handle the usual: cleanings, fillings, and crowns, plus the occasional root canal or extraction. X-rays and preventive care are part of the routine, though you won’t find flashy ads for cosmetic whitening or Invisalign. A single Google review has given them a perfect 5.0, which, while thin on volume, suggests someone walked out without complaint. The office doesn’t push membership plans or subscription cleanings—just the basics, done quietly.

Appointments are made by phone, and the number (605) 332-1500 rings through to a line that picks up after three or four tones. No online booking portal, no chatbot, just a voice on the other end. The block itself is a mix of residential and light commercial, with a laundromat on the corner and a barber two doors down. Parking is street-side, metered on weekdays, free after five.

For directions, the map link is here. The neighborhood doesn’t change much from year to year—just the slow creep of new siding on old houses and the occasional food truck parked by the riverbank.
