Logan Horejsi PA-C
Aesthetic Provider
Logan Horejsi, PA-C, diplomate fellow of the SDPA, has always had a passion for medicine. Logan grew up in Michigan- you may still hear a little Midwest accent. She graduated with a master's degree in biology from Kalamazoo College and was published for her research on fruit flies with Michigan State University. As a collegiate volleyball athlete, Logan led her conference in digs for two consecutive years before an injury ended her athletic career.
Realizing a passion for helping others, Logan obtained her EMT license from Kalamazoo Valley Community College, followed by a Master of Physician Assistant Studies from Wayne State University in 2022. During this time, her sister was diagnosed with melanoma, and Logan herself was diagnosed with a severe dysplastic nevus. These events motivated her to pursue a career in dermatology, where she is devoted to making every patient's experience as comfortable as possible.
Logan relocated to Ventura County, California, where she has been dedicated to practicing medical dermatology, including medical aesthetics. She feels fortunate to learn and work alongside some of the best aesthetic injectors in the country. Logan believes in a multi-modality approach to medicine, tailoring each treatment to the specific needs of her patients. Her goal is to make every person feel beautiful and confident in their own skin, with a focus on self love and enhancing a natural aesthetic.
Outside of her medical career, Logan’s enthusiasm for sports and fitness is evident - she’s even achieved the remarkable milestone of completing an Ironman Triathlon. She also enjoys reading, sunsets, dogs, and a good craft beer.

Uldine Castel MD
Medical Director
Dr. Castel grew up in the Santa Ynez Valley and moved to the East Coast for her educational years. She completed college in New York and medical school at Temple University in Philadelphia. After completing residency at Ventura County Medical Center in 2003, she started work as a Family Physician in the area.
Dr. Castel had done training in facial aesthetics and injections when she worked with HIV positive patients who suffered from facial changes sometimes seen from previous generation HIV medications. In addition to that, she also attended trainings given by top aesthetic providers in Los Angeles. This is where she met Josie Arrigoni.
As they got to know each other, they discovered that they had a very similar philosophy about beauty and how to approach this industry. Dr. Castel believes that beauty is mostly found "under the skin", but sometimes it takes softening lines and smoothing surfaces to be able to fully embrace someone's beauty. Feeling good about yourself is a lifelong, multidisciplinary journey and this is only one, small aspect of achieving it.
