Fontana residents with a Lap-Band can have the band adjusted, checked, or evaluated for removal or conversion at the Rancho Cucamonga office of Davtyan Medical Weight Loss & Wellness, a straight drive west along Arrow Route. The same office is a starting point if you are exploring weight-loss surgery or medication for the first time. Call to book; the first consultation is complimentary.
The drive west from Fontana
Arrow Route, which becomes Arrow Boulevard in central Fontana, runs west from Fontana into Rancho Cucamonga, where Red Oak Street branches off it. From Fontana City Hall on Sierra Avenue, that surface-street route is about 8 miles and avoids the freeways entirely. Drivers from north Fontana can also use the 210 (Foothill Freeway) or Foothill Boulevard west, and those from south Fontana the I-10 west to Haven Avenue.
Fontana has its own Metrolink station at 16777 Orange Way. Metrolink lists both the Fontana and Rancho Cucamonga stations on its San Bernardino Line. Getting off at Rancho Cucamonga's Azusa Court station leaves you a couple of miles short of Red Oak Street, so arrange onward transport.
Fontana by the numbers
The California Department of Finance estimates Fontana's population at 219,774 on January 1, 2026, larger than Rancho Cucamonga's 176,418 and up 0.6 percent from a year earlier.
CDC PLACES model-based estimates for Fontana adults in 2023 show:
| Measure (adults, 2023) | Fontana |
|---|
| Obesity | 33.2% |
| Diagnosed diabetes | 11.5% |
| High blood pressure | 29.3% |
| No health insurance, ages 18 to 64 | 16.3% |
| Routine checkup in the past year | 68.3% |
The last figure is the one band patients should notice. About a third of Fontana adults had no routine checkup in the past year. With a band, a skipped year can mean missing an early sign such as a stretched pouch. Our page on the annual Lap-Band checkup explains what a yearly visit covers.
Coverage for Fontana residents
Like Rancho Cucamonga, Fontana is in San Bernardino County, so the same Medi-Cal plans apply. The state's 2026 plan table for the county shows three Medi-Cal managed care plans, IEHP, Molina Healthcare of California and Kaiser Permanente, plus SCAN Connections for people enrolled in both Medicare and Medi-Cal.
Being in the same county does not by itself mean a plan will cover a given specialist. The practice works with PPO and HMO plans that allow care with Dr. Davtyan. Plans set their own networks and authorization rules, and the office will check your coverage before your visit. For how Medi-Cal plans treat bariatric and revision surgery, see our guide to IEHP, Medi-Cal and bariatric surgery. If you are paying yourself, our page on what affects the cost of band care explains the factors involved.
What a Fontana band patient should plan for
Band care is a series of short visits rather than one big one. The FDA patient guide says people may need anywhere from one to ten adjustments in the first year, and after that it could be months or years between adjustments, though long-term follow-up remains important. For a patient with a band placed years ago, a sensible plan is a first visit to review how the band is working, any fills needed, and then a regular check at least yearly. A fill visit is short, so you can often fit one around a work day.
Surgery is different. If you are planning removal or a conversion, arrange for an adult to drive you home after anesthesia and to be nearby for the first day. And if a band problem turns urgent, such as not being able to keep liquids down or vomiting blood, go to the nearest emergency room in or near Fontana rather than driving to Rancho Cucamonga. Tell the staff you have a gastric band, then call the office.
Frequently asked questions
Can I get to the office from Fontana without using the freeway?
Yes. Arrow Route (Arrow Boulevard in Fontana) runs west from Fontana to Red Oak Street in Rancho Cucamonga, about 8 miles from Fontana City Hall. It has traffic lights along the way, so allow extra time at busy hours, but it avoids freeway merging, which some people prefer right after a fill or when they are not feeling well.
Can I take Metrolink from Fontana to my appointment?
Metrolink lists both the Fontana station on Orange Way and the Rancho Cucamonga station on Azusa Court on its San Bernardino Line. The Rancho Cucamonga station is about 2 miles from the office by road, so plan for a bus, rideshare, or pickup. Check Metrolink's current schedule, since train times may not match a short appointment.
My band was placed years ago and my weight is creeping up. Is it worth coming in?
Yes. Weight regain can mean the band simply needs fluid, but it can also come from a stretched pouch or a band problem, where adding fluid would not help. A visit sorts out which it is. Our guide to weight regain with a band explains the causes and the options.
Can I keep my Fontana primary care doctor while getting band care in Rancho Cucamonga?
Yes. Band fills, checks, and surgical decisions are specialist care, and your primary care doctor still looks after the rest of your health. It helps if the two offices share notes, especially about blood pressure, diabetes medicines, and any weight-loss medication, since these can change as your weight changes. Bring your doctor's name and fax number to your first visit.
