Katerina Helmn, FNP

Founder, Medical Provider

My name is Katerina and I am a Founder at Rejuv Medical. It was born to challenge medical spa and medical office experience. At Rejuv Medical we implement caring, non-judgimental, and personalized approach to every patient. As a provider, I serve you to look and feel your best. As many modern people today, I have been striving for personal and professional growth and implementing my knowledge to enlighten you to do the same.

I’ve had a very successful career as a Family Nurse Practitioner specializing in Dermatology and Aesthetic Medicine in California. I have started my Aesthetics journey in Moscow, Russia and continued in the U.S. I have obtained a Bachelor degree in Nursing Science at California State University, Los Angeles and a Family Nurse Practitioner at prestigious Samuel Merritt University in Oakland, California.

My passion for medicine and helping others started at a very early age, but specific interest in Dermatology and Aesthetic Medicine was facilitated by my own skin issues. I developed a severe form of cystic acne a few years after I came to the U.S. and have seen several dermatologists and primary care doctors. I was given birth control and topical medicines, but acne didn’t resolve.

My journey for healing took me to exploring integrative medicine. I discovered gut-skin connection, food sensitivity reactions, and hormonal imbalances that contribute to adult acne. Few months after applying what I learned about at A4M Anti-Aging institute, my acne cleared up. This is when Rejuv Medical was born. A place where health and beauty are taken beyond what regular medicine has to offer. Aging is a complex process that can be reversed by skin treatments as well as personalized medicine. My goal is to honestly address patients’ concerns and develop a unique skin and overall health maintenance plan.

My vision is to help every human in the world feel their best, be happy, and success in their lives.

I believe in treating the cause of the problem, bridging the gap between natural and conventional medicine while offering the best healthcare possible

Jamie Ancheta

Practice Coordinator

My name is Jamie, and I am a Practice Manager at Rejuv Medical. My goal is for you to have a pleasant and smooth experience coming into our medical office. I serve as a patients’ advocate and share an expertise in service industry experience. At Rejuv Medical, I transform your medical office visit into a unique spa experience.

First, I became Katerina’s patient and immediately fell in love with the practice. It wasn’t an accident that I offered my help to Katerina’s rapidly growing practice. With empowerment and guidance, it was easy to start making impact right away. I wanted to bring a unique flow and compassion to the practice. Also, being a patient myself, I understand everyday challenges we face on the path of beauty, confidence, and optimal health. I can relate to those on their journeys to their best life and would love to support you on this courageous journey.

I certainly have a passion for things being fair. I have recently graduated from California State University, East Bay with a degree in Criminal Justice and would like to continue my path to becoming a lawyer in the near future.

In my free time, I love to explore new restaurants in the Bay Area, spend my mornings in the gym, and attend music concerts and festivals. When I am not out and about, I like to spend time at home while binge watching tv series. I also love perfume, new makeup products, and clothing. My favorite perfume at the moment is Jo Malone Peony and Blush Suede.

Testimonials

Another exceptional and outstanding appointment done. Travelled once again all the way from LA to SF just to see her. It’s totally worth the time and trip fare. Thank you Katarina!

I’ve been going to Katerina for almost a year and I don’t plan on going elsewhere. My friend, who looks great, recommended her and I’m so grateful for this. It’s reassuring to be able to trust someone with my skin/face. She’s done Botox, lip fillers, and Dysport on me and I am more than pleased with her work. She never goes overboard and keeps me looking natural. In fact, I thought I needed more fillers, made an appointment, and she said “nope!” and I truly respect her for this. She’s not trying to make $$$ of her clients. It’s evident that she cares about her reputation, her clients, and her work. Thank you, Katerina, for helping me look better and feel more confident in my skin.

Katarina combines an aesthetic eye with her medical knowledge of bone and muscle to bring forth your best possible look. I am very pleased with her work. I always feel listened to and cared about. I definitely recommend REJUV Medical.

I had the best experience at REJUV Medical. I feel more confident in my skin and the results achieved are natural. I also purchased so of the skin care products and I’m in love. I booked my appointment to come back in a few months and I can’t wait!

Katerina is the best of the best! She is honest and will provide you with the Information you need to do what’s right. When I need some filler or Botox (often) I go to her. I used to fly to LA but there’s no need. Her work is amazing.
