Team RenewMD Fremont

Ruby Castro – Client Care Director – RenewMD

I have been working as a client care coordinator for 15 years now, When I first started with Dr Sethi I noticed from the first day I worked with her the time and care she took with her patients. It is the exact care that I love to give to patients when coming into the practice! I love taking the time to educate and make sure our patients understand their options at Renew MD. At the day I love seeing our patients confident and comfortable with the decisions they make at Renew MD. The choice is yours ladies! I’m here to help answer any questions you may have!

I love the Potenza Treatment! Now that I am in my 40’s it is important for me to work on rebuilding collagen at least 1-2 times a year. I love to keep my skin looking bright and youthful and I love seeing the results on our patients from Potenza as well!

I have 2 beautiful daughters that are my world. You will even have a chance to meet one of them on staff, Kayonni Castro. We do a lot of fun adventures together from working out, hiking, biking, bonfires, boating, spontaneous road trips, to just being a couch potato and binging on a Netflix, Hulu or Prime series. Don’t be shy to ask for my latest recommendations!

Joy Tiangson, Registered Nurse – RenewMD Fremont

I was always interested in skin care and beauty. When I studied to become a nurse I wanted to align my passion with my occupation. When I started working for RenewMD I knew that this job was meant for me!

As a woman with a lot of hair, I felt that when I get laser hair removal I become more confident and liberated. So when I do laser hair removal on my clients I get excited knowing that they feel how I feel when they get this treatment done.

During my time off, I like shopping, traveling and spending time with my family ,friends and my furry baby, Tootsie.

Lisa Le, Registered Nurse – RenewMD Fremont

I graduated from Samuel Merritt University with a Master of Science in Nursing in Family Nurse Practitioner.

I started my career at Stanford Healthcare – Valley care in 2017, and I am still currently working there. At a young age, I was always interested and very passionate about skin care, makeup, and finding different ways to enhance one’s beauty. During the time that I was pursuing nursing, I was working at Macy’s for 5 years in the cosmetic line, and I always knew that I wanted to pursue aesthetic nursing. I am very grateful and thankful to have met Dr. Sethi, who is very knowledgeable and very passionate in what she does. I am proud to be part of RenewMD and to be able to learn from Dr. Sethi.

My favorite treatment that I love to do and to perform is the Picosure machine. The Picosure is an aesthetic laser treatment that really focuses on restoring youthful skin, and there is no downtime! I have personally had Picosure done myself and I love the result.

On my free days, I enjoy spending time with my Shih Tzu Olive and spending time with family and friends. I also enjoy traveling and going out to eat!

Stefany Sandoval – Medical Assistant and Body Sculpting Specialist – RenewMD Fremont

As a little girl I have always had an interest in the medical field. Once I became a young adult I really started to focus more on medical aesthetic shows such as “Botched” and social media pages for plastic surgery/medical spa offices and realized that I could also be working in the same field. The fact that I was able to find an office that had technology that treats all skin types and team members that care about patient satisfaction/results was like finding the pot of gold at the end of a rainbow.

My favorite treatment in our office has to be microneedling. Growing up I had a lot of acne all over my face. This really messed with my self esteem badly and I would NOT like for my photos to be taken. I feel like my self esteem has really skyrocketed and can walk confidently out of my house with no makeup.

When I’m not working at Renew MD I love to be with family and friends. I really love to play volleyball on the weekends. I also enjoy watching a lot of shows and movies such as Game of Thrones and vikings.

Misty Mua’ava – Medical Assistant – Body Sculpting Specialist – RenewMD Fremont

I joined the Medical Aesthetics field because I wanted to help both men and women feel more comfortable and beautiful in their own skin.

I love to treat patients on Emsculpt Neo and I love getting Microneedling with PRP .

When I am not at work, I love to spend time with my family, I love to play COD and I love the Raiders :)

Megan Pope MSN, FNP-BC - RenewMD Stockton

I’ve been a registered nurse since 2011 and my background includes orthopedic/trauma nursing, nursing clinical instructor, home health nursing, and aesthetics. I’ve been a nurse practitioner since 2021 and currently work in dual specialities as a NP in aesthetics as well as urology.

I was drawn to aesthetics because as someone who personally struggled with years of acne and self esteem issues, I’ve grown to realize that learning to love the skin you’re in and feel confident is so important to our mental health. When I help my patients feel beautiful inside and out through the treatments provided and getting to know them, it makes my job that much more rewarding and I know I ended up in this specialty for a reason.

When I’m not working I’m spending time with my fiancé, 3 dogs, 2 cats, and 28 chickens :) I enjoy being outdoors, gardening, cooking, and traveling.

Gissell Stone, Registered Nurse - Stockton & Fremont

I began my nursing career with a new grad residency at Stanford Healthcare Valleycare. I worked for SHVC for two years, initially in Medical/Surgical, then in Labor & Delivery. During my second year, I decided to pursue and explore aesthetics - part time, as well. RenewMD was my very first job in the Medspa world. Almost instantly, I recognized that I LOVED aesthetics. Skin care, injectables, all of it - I was hooked! As my passion grew, I decided to leave the hospital so that I could put all my focus on aesthetics & fine tune my skills. I am forever grateful to Dr. Sethi for allowing me the amazing opportunity to learn & grow under her guidance!

Lip filler! and Picosure laser facial - obsessed with pico

I enjoy road trips with my fiance and Aussie pup, Chance - finding fun places to camp and be outdoors. I'm a bit of a DIY crafter (beginner) but I love working on small projects and making hand-made decor. I also enjoy relaxing on my couch, with a glass of red wine, creating reels or compilations of Before & After photos of my beautiful patients.
