As my ASDS fellowship year comes to an end, I’m th As my ASDS fellowship year comes to an end, I’m thrilled to share that I’ll be staying on at UnionDerm as an attending physician.

To the patients who trusted me with their care this year — thank you, from the bottom of my heart. Being part of your journey has been such a privilege, and I’m so looking forward to continuing to care for both new and existing patients across our Greenwich, Central Park, and Union Square offices.

I’m deeply grateful to Dr. Chapas and the physicians who poured into me and invested in my growth this year. This chapter has meant more than I can put into words — and I cannot wait for what’s next!

With gratitude 🩵

Dr. Victoria Humphrey

—

One of the best parts of having a fellowship program is getting to work closely with talented young physicians at such an important stage in their careers. From the beginning, it was clear that Dr. Humphrey was someone special.

She is thoughtful, hardworking, incredibly detail-oriented, and deeply committed to her patients. Over the past year, I’ve had the privilege of watching her grow as a cosmetic dermatologist, and I couldn’t be happier that she has chosen to stay at UnionDerm.

We are thrilled to welcome her to our attending physician team and excited for our patients to continue benefiting from her expertise and care.

Our team had a ball last night 🎾⛳️ A little frien Our team had a ball last night 🎾⛳️

A little friendly competition, a lot of laughs, and absolutely zero surprise that our dermatologists ended up being great at the games too. From lawn pong and corn hole to cocktails, snacks, and nonstop commentary, Lawn Club was the perfect excuse for some team building outside the office. Nothing better than a night with the UnionDerm crew 💙
Did you catch our very own Dr. Ugonabo on CBS Morn Did you catch our very own Dr. Ugonabo on CBS Mornings earlier this week? ✨

She joined the conversation around the viral neck-care debate taking over the internet, sharing her expert take on how to keep skincare simple, effective, and realistic for patients.

We’re always proud to see our physicians leading conversations on national television and serving as trusted voices in dermatology and skincare. Thank you to CBS Mornings for having her. 💙
Exciting yet bittersweet news to share! 🎉 After an Exciting yet bittersweet news to share! 🎉
After an incredible journey at @unionderm, from fellow to attending physician and getting to help launch our Greenwich office, I’m excited to announce that I will be pursuing a yearlong Mohs Micrographic Surgery fellowship with Dr. Naomi Lawrence at Cooper University Hospital in New Jersey. I am thrilled at the opportunity to grow and broaden my surgical skillset.

UnionDerm truly shaped the physician I am today. I am so grateful for the mentorship of our medical director Dr. Chapas and attending physicians, the team that became family, and the experiences that made this next step possible.

And to my patients, thank you for trusting me with your care. It has been my absolute privilege and honor.

We are so proud of Dr. Rambhia and all that she has accomplished during her time at UnionDerm. 

Our physicians are always pushing forward—continuing to train, refine, and expand their expertise at the highest level. Dr. Rambhia’s next step is a reflection of that commitment to excellence in patient care and surgical innovation.

She will be deeply missed by our team and her patients, and we can’t wait to see all that she accomplishes in this next chapter.

Rosacea Awareness Month reminder: redness is treat Rosacea Awareness Month reminder: redness is treatable.

Rosacea can be frustrating, especially when redness feels constant or unpredictable. Many patients assume it’s something they just have to manage or cover.

In reality, we have effective treatment options. I often use Excel V to target the visible blood vessels contributing to redness and flushing.

The before & after here shows what’s possible with a thoughtful, consistent approach.
Scars aren’t one-size-fits-all—and neither is the Scars aren’t one-size-fits-all—and neither is the way we treat them.

From acne scars to surgical scars, the right approach depends on scar type, skin, and timing. In our latest What’s New, Dr. Tatyana Petukhova breaks down how she evaluates scars and the treatment strategies she uses to actually improve them—think beyond just lasers.
