Lap-Band care for Ontario, CA residents

If you live in Ontario and have a Lap-Band, or are thinking about weight-loss surgery, the nearest office of Davtyan Medical Weight Loss & Wellness is on Red Oak Street in Rancho Cucamonga, a short drive north of Ontario. Ontario residents come there to have a band tightened or loosened, checked after a long gap, or assessed for removal or conversion. The first consultation is complimentary.

Getting from Ontario to Red Oak Street

The office is at 8330 Red Oak Street, Suite 201, a short street off Arrow Route, a few blocks from Haven Avenue. From most of Ontario, the simplest route is the I-10 (San Bernardino Freeway) to the Haven Avenue exit, north on Haven to Arrow Route, then a short way east to Red Oak Street. From Ontario City Hall on East B Street, the drive is about 7 miles.

If you do not drive, Metrolink's Rancho Cucamonga station on Azusa Court is served by Omnitrans buses, including the ONTConnect service to Ontario International Airport, according to Metrolink. From that station the office is still roughly a 2-mile drive, so line up a bus connection, rideshare, or a friend for the final leg.

Ontario's health picture in numbers

Ontario is growing. The California Department of Finance estimates its population at 187,863 on January 1, 2026, up 1.36 percent in a year, compared with 0.05 percent for San Bernardino County as a whole. Some newcomers arrive with a band that was placed somewhere else and no local surgeon to look after it.

CDC PLACES, which produces model-based estimates for each city, puts adult obesity in Ontario at 33.6 percent and diagnosed diabetes at 12.0 percent for 2023. Two other Ontario estimates matter for band care: 17.0 percent of adults aged 18 to 64 had no health insurance, and 12.6 percent reported lacking reliable transportation in the past year. Both can make regular follow-up harder, which is why the coverage and transport options below are worth checking early.

Medi-Cal and coverage for Ontario residents

Ontario is in San Bernardino County. The California Department of Health Care Services (DHCS) lists the county as a Two-Plan model county, and its 2026 table names three Medi-Cal managed care plans there: Inland Empire Health Plan (IEHP), Molina Healthcare of California, and Kaiser Permanente. DHCS also lists SCAN Connections as a plan for people who have both Medicare and Medi-Cal.

IEHP's own Medi-Cal page says its plan provides no-cost, round-trip rides to primary care doctors and medical specialists, booked through IEHP Transportation. If you have IEHP Medi-Cal, ask about rides when you schedule. The practice works with PPO and HMO plans that allow care with Dr. Davtyan. Whether that includes your Medi-Cal plan is something the office will check for you. Our guide to IEHP, Medi-Cal and bariatric surgery explains how these plans handle bariatric and revision care, and the insurance and financing page covers private insurance.

What Ontario band patients typically need

Band patients in Ontario usually need one of a few things:

Restarting band care after a gap. People who moved to Ontario often have not had a fill or check in years. The FDA labeling describes frequent, long-term follow-up as required after weight-loss surgery, and a long gap is a reason to come in, not a reason to feel embarrassed.
Fills. Short visits, often several in the first year and further apart later. Our page on fills and adjustments explains what happens.
Weighing removal or conversion after weight regain or band symptoms.

If you work long or irregular shifts, say so when you book and ask for a time that fits. It is wise not to schedule a fill right before a shift with no food or water breaks, so you can follow the eating plan you are given.

Frequently asked questions

I just moved to Ontario and my band surgeon is out of state. Where do I start?

Ask your previous surgeon's office for your operative report and fill history, then call the Rancho Cucamonga office to book a first visit. You do not need every record before you call. Our guide for transfer patients lists what to gather and what the first evaluation usually covers.

Can I get a ride to my appointment through IEHP?

IEHP's Medi-Cal page says the plan offers no-cost, round-trip rides to primary care doctors, medical specialists, and urgent care, and gives the IEHP Transportation number, 1-800-440-4347 (TTY 1-800-718-4347 or 711). Rides are set up through IEHP, not through the doctor's office, so call them once your appointment is booked.

Should I drive to Rancho Cucamonga or go to a nearby ER if my band blocks?

If you cannot keep water down, are vomiting blood, or have severe chest or abdominal pain, go to the nearest emergency room or call 911. Do not drive across town for an office appointment first. Tell the emergency staff you have a gastric band, and call the office once you are safe so your surgeon can follow up.

Is Ontario covered by the same Medi-Cal plans as Rancho Cucamonga?

Yes. Both cities are in San Bernardino County, so the same county Medi-Cal plans listed by DHCS apply. That keeps things simpler than for residents of neighboring Los Angeles County cities, where the plan list is different. Your plan's own network and authorization rules still decide which specialists you can see.
