Why One & Only
Hospitality, at the level of a memory.
Karina spent years running the front of luxury hotels. That is the standard behind every One & Only event.
Run by an operator
A luxury hotel operations background means the timeline, the vendors, and the recovery are handled before you notice.
Bilingual and bicultural
Fluent in Mandarin and Cantonese, and at home in Chinese and Korean traditions. The rites handled properly, for the couple and the family.
Every detail intentional
Every color, flower, light, and place setting exists for a reason. Nothing is there by default.
Truly yours
The event is a reflection of you, never a template. Your one and only, every time.
The Operator Behind One & Only
Hospitality is not a job to Karina. It is how she thinks.
One & Only is led by Karina Zhang, an event manager with a Marriott luxury hotel brand and more than ten years in premium hospitality across China and Hawaii. She has managed VIP guests, led large teams, and handled the thousand details a guest never sees. That is the standard she brings to your celebration.
She plans fluently in Mandarin and Cantonese, and she is at home in the customs of Chinese and Korean celebrations, from the tea ceremony to pyebaek and dol. Every event is treated like a guest she is personally responsible for.

References & Reviews
People who have worked with her.
Karina has an incredible eye for detail. She took our vision and elevated it into something far beyond what we imagined. Every vendor was coordinated perfectly, everything stayed on schedule, and our guests couldn't stop talking about the experience.
Emily Chen · Luxury Real Estate Advisor
I've worked with many event planners over the years, and Karina stands out because she listens first. She understands the purpose behind an event and builds every detail around it. Professional, organized, and always one step ahead.
Daniel Kim · Technology Executive
As someone who works behind the scenes, I can immediately tell when an event is well managed. Karina keeps vendors aligned, communicates clearly, and creates beautiful spaces that photograph effortlessly.
Sophia Nguyen · Wedding Photographer
Karina is one of the most organized professionals I've worked with. She anticipates problems before they happen and always arrives with thoughtful solutions. It made the entire planning process enjoyable.
Grace Huang · Healthcare Executive
She introduced ideas we would have never considered ourselves, and every single one made the event stronger. Our guests are still talking about the experience months later.

Every recommendation Karina made ended up improving our event. Her creativity never felt excessive. Instead, it aligned perfectly with our vision and elevated the entire experience.

Investment
Priced to your celebration, not a menu.
Every event is different, so a single fixed price would only ever be a guess. Your budget, your guest count, and what you choose to bring in all shape the number. A simple styled setup and a full celebration with custom florals, decor, and extras like a dessert table or an ax throwing lane are not the same event, and should not carry the same price. So we start with a conversation. Tell us your budget and your vision, we design to it, and you receive one clear proposal with everything itemized. No hidden costs, no pressure, and you know exactly what you are paying for before you say yes.
