Maven Haus was created from the belief that aesthetics & wellness should be grounded in integrity, intention, and expertise…not trends or volume.

Founded by registered nurse & military veteran Ashley Walkup; Maven Haus reflects a values-driven approach to care shaped by discipline, service, & accountability. As a mother, Ashley brings a deeply human perspective to the work…one rooted in patience, thoughtfulness, & long-term well-being.

Maven Haus was never meant to be a one-provider practice. It was designed as a collective - a house of experts across the spectrum of all things “self-care.” Aesthetics, skin health, & regenerative medicine are at the forefront, with the focus being overall wellness.

Each provider has been carefully chosen for their experience, ethics, & commitment to exceptional care.

Maven Haus operates under the medical direction of Dr. Sundar Natarajan, MD.

Meet the Founder

Ashley Walkup, BSN, RN, PHN, began her career serving in the United States military before transitioning into healthcare & aesthetics. Her background instilled a respect for precision, structure, & responsibility. These principles continue to guide how the Maven Haus collective operates.
