Jennifer Howes, Ph.D.
Executive Director of Student Wellness Services
I completed my undergraduate work at UCLA and received my Ph.D. in Clinical Psychology from the California School of Professional Psychology at Alliant International University. Prior to arriving at Caltech in 2011, I worked with a diverse group of students at the Claremont Colleges and maintained a small private practice. While I now focus on administrative aspects of Health and Counseling Services, I enjoy supporting students through programming and outreach events related to mental health, emotional wellbeing, identity development, physical fitness, and the Caltech Cares initiative.
Lee H. Coleman, Ph.D., ABPP
Assistant Director of Counseling Services; Coordinator of Groups and Outreach
Education: Ph.D. in Clinical Psychology, Miami University, 1999
Professional Affiliations: Diplomate, American Board of Professional Psychology; International Mindfulness Teachers Association
Professional Interests: Depression and anxiety; preventing depressive relapse; suicide prevention; emotion regulation; mindful awareness skills
Liaisonships/Committees: Liaison to Blacker and Ricketts Houses
Hobbies/Self-Care: Meditation, playing bass guitar, cooking, and reading
Wellness Tip: Meditation isn’t necessarily something you have to set aside separate time for. It’s an attitude of welcoming awareness that you can bring to whatever you happen to be doing anyway.
This is my 15th year at Caltech. It’s an incredible privilege to work with such talented, insightful, and delightful students. There’s so much that Wellness Services can offer you - please come talk with us, and let’s find out how we can work together.
Charisma Bartlett, Ph.D.
Staff Psychologist, Asian/Asian-American Focus
After traveling through 39 countries around the world as a student, tourist, and self-proclaimed international food taster, I completed my doctorate in Clinical Psychology in 2010 and joined Counseling Services in 2011. My interest areas include cultural identity, spirituality and existential issues, and advocacy for the mental health needs of Asian and Asian American students. As a liaison to International Student Programs (ISP), I provide adjustment and ongoing support to international students. Through my diverse experiences at local universities and hospital settings, I am also able to work with a student’s relationship with food and body image.
I believe it’s never too late to make mindset shifts that can make a significant impact on one’s present circumstances and future trajectory. My therapeutic style is warm, relational, and focuses on your strengths and goals, in addition to managing areas of impasse. I assess how past relationships and experiences may be connected to arrested development in your current context. Through collaborative exploration, I can help you discover deeper connections in your relationships and move toward a greater sense of purpose and work-life balance.

Wellness Tip: Always make time for yourself.
Dr. Lal has trained and worked in different hospitals and university health settings. Throughout his career, he has contributed to the research literature, has written online articles, and has been involved in radio shows addressing mental health issues.
He uses an integrative approach to psychotherapy focused on increasing awareness into factors contributing to struggles and works collaboratively to increase one’s ability to manage symptoms. Symptom management provides immediate relief while allowing for the therapist and patient to work collaboratively to gain an in-depth understanding of the patient’s struggles. This increased awareness leads to long term improvement and increased life satisfaction.

Wellness Tip: The small things make a difference – 3 healthy meals a day, 8 hours of sleep, playing with your cat or dog, reading for fun, sketching, playing an instrument at night, meditating, exercising, calling a friend, or going for a hike or beach day. We need to take care of ourselves in order to take care of others and reach our goals. We all have difficult moments, days and times; reach out to a friend or other supportive individual. Be that supportive individual for someone else.
