Welcome to Alevizos Medical
Alevizos Medical in Irvine, California, specializes in anti-aging medicine, helping patients to look and feel energetic, having more lean muscle mass, and happier.
Founder John Alevizos, DO, is a board-certified family practice physician who has a passion for anti-aging medicine. He follows the principles of integrative medicine to combine the most beneficial aspects of conventional and alternative methods, and provide a holistic approach to patient care.
His primary focus is the use of bioidentical hormone replacement therapy (BHRT) to address hormone imbalances. Less-than-optimal levels of essential hormones like estrogen and testosterone can cause issues such as weight gain, loss of sex drive, lack of energy, moodiness and anxiety, trouble sleeping, and depression.
Dr. Alevizos and his team also offer effective long-term solutions to weight loss to help patients look and feel their best and enjoy life to the fullest.
He treats a range of sports injuries using innovative products like platelet-rich plasma (PRP) to encourage tissue healing.
Find out more about looking and feeling younger by calling Alevizos Medical or booking an appointment online today.
