If you live in The Ridges, our office is closer than your favorite restaurant in Downtown Summerlin. Eight minutes door to door on a normal afternoon, depending on which gate you come out of and how the lights treat you on Town Center Drive. We are at 851 South Rampart Boulevard, Suite 230, in the Tivoli Village area — same side of the 215 as you, no freeway required for the southern part of the community.
I know that sounds like an opening pitch. It is actually just the most useful thing I can tell a Ridges resident in the first few sentences: how close, how easy, no surprises.
This page is meant to give you a real sense of who we are and what visiting us is like, written without the usual website noise. If you came here looking for a specific service, the menu at the top of the site will take you there faster. If you want a feel for the practice before you call, this is the page for that.
We have been at this address since 2000. Over the years, a fairly steady stream of patients from The Ridges has found their way to us — usually by referral from a neighbor at Club Ridges, or because someone mentioned us at the Bear’s Best clubhouse, or because a real estate agent recommended us when a family relocated into Promontory, Falcon Ridge, or Boulder Ridge. We do not run aggressive marketing inside the community. The patients who come to us tend to come quietly, and most of them stay for years.
A few patterns we have noticed in three decades of treating Ridges families:
They have usually tried other dentists. Many Ridges patients have lived in two or three other cities — Newport Beach, Boca Raton, Aspen, the Bay Area — before settling in Summerlin. They have been treated at expensive practices in those cities. They have a calibrated sense of what good dentistry feels like. When they come to us, they are comparing us to their last dentist somewhere else, not to the corporate office on Charleston.
They care about the work, not the chrome. The most common thing we hear at the end of a first visit is some version of “you actually took your time.” Not “your office is beautiful” — they have nicer ones at home. Not “your equipment is impressive” — they expected that. Just: you did not rush, you explained things clearly, you were not running a script.

A photo of your actual office building exterior also works well here.]
Privacy matters more than people admit. A handful of our Ridges patients are recognizable to anyone who pays attention to those things. We do not have a back entrance or a private VIP wing — the practice is a single floor, run by a small and consistent team. What we do have is a culture of not talking about who comes in. The front desk has been staffed by the same core people for years. Nobody on staff treats it as gossip when someone notable walks through.
They wait too long when something feels off. This one is universal but more pronounced in successful, busy people. A small chip, a tooth that is mildly sensitive when they drink coffee, a crown that does not feel quite right after a flight. They put it off because nothing hurts enough to interrupt the week. We see those small problems become bigger ones often enough that it is worth saying clearly: most things we treat are dramatically easier when they are caught early.
A few patterns we see more often from this neighborhood than from others:
Cosmetic refinement, not transformation. Most Ridges patients are not asking for a complete smile makeover from scratch. More often it is a single veneer that has started to look slightly different from its neighbors after fifteen years. A whitening tune-up before a wedding or a charity event. A small bonding correction that has been bothering them since they noticed it in a photograph. Subtle work, done well, that nobody else would ever consciously pick up on. The goal is to look like yourself on a good day, not like someone else.
Implant work for parents and grandparents. A lot of our Ridges patients have parents living with them or visiting for extended periods. Multigenerational households and frequent family stays are common in the larger homes. We do a fair amount of implant and All-on-4 work for the parent generation, often scheduled to fit visits from out of town. If you are wondering whether a family member can fly in, do a workup, and have meaningful work done in a single trip, the answer is often yes — call us in advance and we will plan around it.
Athletic mouthguards for teenagers. Sig Rogich Middle School and Palo Verde High School both draw from The Ridges, and a lot of those students play hockey, lacrosse, water polo, or contact sports at a competitive level. Custom mouthguards from a digital scan fit better than the boil-and-bite ones from the sporting goods store, do not interfere with breathing or speaking, and — most importantly — actually get worn during games.
Botox and filler combined with dental visits. Dr. Cohan is accredited through the American Academy of Facial Esthetics, which means she is trained in Botox and dermal fillers in addition to dentistry. For Ridges patients, getting both done at one office, by someone who understands the underlying facial structure that supports your smile, is more convenient and more consistent than splitting care between a dentist and a separate medical spa.
A few specifics, written without marketing gloss:
The schedule runs one patient at a time. This is not a slogan — it is how the appointment book is built. Dr. Cohan blocks off the time your visit needs and is not bouncing between three operatories with other patients waiting. If your appointment is at 10am for a single crown, we are not also fitting in a cleaning at 10:15. This is the main reason we cannot see thirty patients a day, and the main reason patients consistently say they did not feel rushed.

Dr. Marianne Cohan owns the practice and has done so since 2000. She graduated from the State University of New York at Buffalo in 1994, has been practicing in Las Vegas since 1996, and holds active credentials from the American Academy of Cosmetic Dentistry, the American Academy of Facial Esthetics, the American Academy of Implant Dentistry, and the Academy of Laser Dentistry. The point of those acronyms is not the wall they fill — it is that her continuing education is real and ongoing. The techniques she uses today are genuinely different from what she used in 2010, and patients who have been with us for a long time notice.
The technology is current — 3D CBCT cone-beam imaging for implant planning, AI-assisted review of digital X-rays, and TRIOS intraoral scanners instead of impression putty. Most well-run practices in higher-end neighborhoods have similar equipment now, so this is more about meeting expectations than exceeding them. The difference Ridges patients tend to comment on is not the imaging — it is the digital scanner, which makes crowns and Invisalign noticeably more accurate and faster than they were a few years ago.
Sedation is available for any procedure if you want it. Plenty of accomplished, composed people are genuinely anxious in a dental chair, and we would rather have you sedated and comfortable than white-knuckling through an hour of work and dreading the next visit.
Because it is one of the most common questions we get from people who have just moved into The Ridges from another city: a typical first visit with us takes about an hour, sometimes a bit longer. We ask you to fill out new patient forms online before you come in so the appointment itself is not consumed by paperwork. When you arrive, you will be brought back within a few minutes — we do not run a waiting room full of people watching the same television.
The visit itself is structured around getting an honest baseline. We take a full set of digital X-rays and a 3D scan, perform a thorough exam, do an oral cancer screening, and then sit down to actually talk through what we found. If you want a cleaning the same day, we can usually accommodate that. If your situation is more complicated, we will lay out a proposed plan in priority order — what is genuinely urgent, what can wait, what is optional, and what each piece will cost — and we will email it to you so you can think it over without pressure. Ridges patients in particular tend to appreciate that we do not push for same-day decisions on larger treatment.
The shortest route depends on which gate you exit from. From the main Town Center entrance and points north, the simplest path is east on Town Center Drive, north onto the 215 Beltway, exit at Charleston, east on Charleston, north on Rampart. Nine to twelve minutes depending on traffic.
If you are coming out of the southern gates closer to Far Hills, it is usually faster to skip the freeway entirely: south on Hualapai, east on Sahara, north on Rampart. Eight minutes on a quiet morning.
Parking is in the lot directly adjacent to the building. We are on the second floor, suite 230, with the elevator on the right as you enter the lobby.
Do you have a preferred patient program for people without traditional dental insurance?
Yes. The plan covers two cleanings, exams, and X-rays per year and includes a discount on additional treatment. It exists because a meaningful share of our patients are self-employed or run their own businesses, and traditional dental insurance often does not fit their situation. Details are on our preferred patient page.
Can you coordinate with my dentist or specialist in another city?
Often, yes. We have patients who split their year between Summerlin and another home, and we routinely send records back and forth with offices on the East Coast and in California. Tell us the situation in advance and we can schedule things to fit around your travel and avoid duplicating work.
What about appointments for visiting family — parents in town for a week, kids home from college?
Just call ahead with rough dates. We can usually find a slot, and we can often combine multiple family members into back-to-back appointments so it is a single trip from The Ridges instead of three.
My current dentist recommended a treatment I am not sure about. Will you give a second opinion?
Yes, regularly. Bring your records and X-rays if you have them, or we will take our own. Dr. Cohan will give you her honest read — sometimes that confirms what you were told, sometimes it does not. There is no obligation to switch your care to us, and we will say so before the appointment starts.
Do you take same-day emergencies?
We hold time in the schedule for them every day. Call 702-341-9160 and tell whoever answers that it is an emergency. If it is after hours, leave a message and Dr. Cohan returns emergency calls personally.
If you want to come in, the easiest first step is a phone call: 702-341-9160. We will ask a couple of questions, find a time that works, and walk you through any new patient paperwork before your visit so the appointment itself is not consumed by forms.
If you would rather see Dr. Cohan before committing to a visit, we offer a virtual consultation — about fifteen minutes, video, no obligation. It is a useful way to have your specific situation looked at and your questions answered before you book anything.
We are eight minutes away. We will be here.
