The people behind the light.
A small studio in the Chicago Loop. The dentist who plans and carries out your treatment, and the practice manager who looks after you from the first call.
Dr. Jonathan PhenDMD, MMS
Dr. Phen opened Helios Dental Center in the Chicago Loop in October 2026. He plans every case himself and carries out the work.
Dr. Phen’s approach to dentistry is a holistic one. With a master’s in medical science, he knows how oral health is connected to the rest of your physiology. He looks at the whole mouth rather than one tooth at a time, and plans for the years ahead, not only the next procedure.
He played piano competitively for twelve years, and it’s with this steady-handed focus Dr. Phen approaches his surgeries.
“My job isn’t to sell you the most expensive treatment plan. My job is to find a treatment that’s right for you.”
