Olivia Tween

Clinical TMS Coordinator & Technician

Olivia acts as our primary liaison between patients, providers, technicians, and insurance companies, managing care teams, helping to resolve issues with billing, and coordinating referrals. In addition, she administers TMS treatments, performs mental status examinations, and assesses treatment progress. 

Prior to joining Madison Avenue TMS & Psychiatry, Olivia worked as a residential counselor at Silver Hill Hospital, where she supported people through a four-week residential program focused on Dialectical Behavioral Therapy (DBT). 

“In both roles, I’ve had the privilege of watching patients gradually transform into healthier, more vibrant, and hopeful versions of themselves,” says Olivia. “It is a privilege to guide people through something that can at first feel frightening and uncertain. Doing so alongside a team of technicians who bring skill, compassion, and genuine encouragement to every interaction has been deeply rewarding. 

“I am so proud to be part of a practice that puts patient care first and believes in each person’s capacity for change.”

Lana Baroni

TMS Technician

Lana is experienced in both TMS therapy and clinical psychology, completing psychoanalytic training both here in the United States and in Brazil. 

“One of my favorite aspects of working as a TMS technician is the opportunity to connect with patients on a personal level, hearing their histories and learning about their trajectories,” says Lana. “It’s rewarding to witness their progress throughout the treatment, often within just a few weeks, and to see the positive changes that TMS can bring to their lives.”

Michael Efremov-Kendall

Practice Administrator & TMS Technician

Michael has supported patients at Madison Avenue TMS & Psychiatry for four years, serving as both a Practice Administrator and a certified TMS Technician. 

“Working with patients through their TMS treatment course has been rewarding over the years because I get to help destigmatize many of the stereotypes associated with mental health,” he says. “I have learned that no two cases are the same.”

Outside of the office, Michael enjoys camping, cooking, and comedy.

“Dr. Woo and team are highly professional and caring. They seem genuinely interested in alleviating your symptoms and helping you on your journey to feel better.” 

“I came in with severe depression. Dr Woo and his staff were very accommodating and explained the process very clearly. They were very knowledgeable and thorough. They made me feel comfortable and informed. I finished the treatments and felt my depression had significantly improved. I highly recommend Madison Avenue TMS & Psychiatry.”

“I can’t recommend Dr. Woo and his clinical staff enough. I had a lot of questions, and they were extremely helpful and responsive. Their responsiveness and flexibility made getting my regular TMS treatments much easier than they could have been.”

“Dr. Woo and his outstanding staff were amazing, encouraging and supportive through a sometimes difficult treatment protocol.”

“My depression has lessened and I do think the treatment and the personal care of the team were beneficial. Thank you. You are a blessing.”
