After having her daughter, Mary Beth was ready for a transition and the opportunity to work at Ketamine Clinics of Los Angeles offered her the work/life balance she was seeking. She believed this clinic would be a good fit, since many of her patients struggled with postpartum depression, a condition which responds well to ketamine infusions and is safe for postpartum and breastfeeding mothers.

Mary Beth trained extensively under Dr. Mandel, learning how to care for our patient population exactly as he does. She has a warm bedside manner, a thorough understanding of the conditions we treat, and is a natural leader among our medical staff. Since 2017, she has connected with our patients and bonded with the team. Mary Beth upholds the high standard of care that Dr. Mandel has established.

After working in the medical field for 7 years as a Project Assistant at USC Cancer Center, she was eager to start her career as a nurse. Her interest in becoming a nurse began when she was a little girl and was inspired by her mom’s commitment to caring for the elderly. Her mom taught her the importance of respecting your elders and the difficulties elder patients endure, which inspired Denisse to give comfort to them during their senior years.
