Virtual Care Team

Robert Pampin


As Robert began his college education, science took an incredibly strong hold on his interest. The semesters went on and he realized he also enjoyed philosophy and the humanities. Throughout, he met key mentors who would drive these passions further. Inevitably, this collective experience led him to apply his efforts to a career in medicine—in particular, Family Medicine. This specialty afforded him the ability to meld all of his interests and see patients in the context of our complex and ever-changing healthcare, and social, systems.

As his career was developing, he came to realize that most of the disease he sees is in large part preventable. In particular, the current obesity epidemic has been exploding with major impact on public health. This being the case, Robert has recently become board certified in bariatric (weight loss) medicine by the American Board of Obesity Medicine (ABOM) and has integrated this into his care. With 2/3 of all adults in the US being either overweight or obese, there is much work to be done. He has been quoted as saying that “If I can prevent more disease than I treat over my career, then I have done some good.” That is how he approaches his practice and why he is thrilled to be part of the Crossover Health family, in part because of its symbiotic dedication to patient-centric care.

Robert was born in the Bronx, and completed his ABFM certification and training in NYC, so being at Crossover Midtown is like coming home again. He is thrilled to add his experience to the team and is dedicated to offering the highest level of integrative care possible to his patients. Outside of the office,
Robert enjoys time with family and putting into practice what he preaches. Diet and exercise are important parts of his life and he feels that attempting to lead by example is an important responsibility of a physician.

He is often said to have a comedic sense and loves to find the humor in life as well. Since his children were young the family has frequented Manhattan to enjoy the educational as well as the cultural diversity it presents.

What makes me unique:
I have always been open-minded and enjoy intellectual challenges. I seek this in all facets of my life whether in medicine, humanities, or music. I truly enjoy learning from others and sharing ideas to find continued growth and promote wellbeing.

Why do I practice healthcare:
As my career has progressed I feel the need to help people understand that the role of primary prevention is critical. Further, it is far more important to prevent disease and reverse harmful trends, rather than wait and treat patients once it is well established.



Yvonne has been practicing medicine for over 20 years as a board-certified family physician. Her professional interests include Women’s Health and Integrative Medicine.  Having trained in a medically underserved area, she came to truly appreciate the importance of comprehensive healthcare within the context of medicine and societal impact. Recognizing that although many people share similar health experiences, there is not a single generic approach to optimal health for all patients. In addition to including the latest evidence-based treatments in her practice, she believes in the integrative model of medicine, inclusive of practices designed to support health in body, mind, and spirit.

In her spare time, she enjoys spending time with her husband and two children, traveling the world, and seeking new adventures. She also enjoys DIY projects and herb gardening.

I feel privileged to be practicing medicine. To promote wellness and alleviate suffering is a high calling to which I have always aspired.

  • Bachelor of Nursing, The University of Texas at Austin

What makes me unique:
I am very easy-going and laid back in almost all situations, and I also have the compassion and empathy necessary to care for my patients. My background as a Neonatal ICU nurse, as well as an inpatient psychiatric nurse for children and adults with eating disorders, has given me the experience and tools necessary to help support patients of all ages.

Why do I practice healthcare:
It’s a profession that never stops giving. I learn new things everyday, there’s always opportunity for growth, and it is so rewarding to make a difference in someone’s life.



Working as a physical therapist is incredibly rewarding for Ashley, because she gets to make a difference in the lives of her patients. She loves spending one-on-one time with them, and helping each and every one achieve their goals—whether that be returning to running, working out, playing with grandchildren, or just getting through the day without pain. In addition to helping improve their quality of life, she enjoys getting to know them personally throughout their course of treatment.

Ashley earned her B.S.Ed. in Health Science Studies from Baylor University, and her doctorate in Physical Therapy from Texas Woman’s University.

Heather Barnes

Physical Therapist

Simply put, Heather enjoys working in healthcare because of the relationships with patients and colleagues that have been built over the years. Some of her colleagues have even become lifelong friends. She feels she has made an impact on someone’s life throughout their treatment, and the gratification from that is something truly special—and unique to working in healthcare. She also thrives in a challenging career path, and healthcare has not disappointed! Despite any adversity she faces, she’s encouraged to maintain her integrity while striving to achieve her own personal goals, as well as the goals of her patients.

Originally from Washington DC/Northern Virginia, Heather loves to travel with her husband (and their dog for domestic trips), camping, hiking, participating in yoga and barre classes, and reading (she’s a huge bookworm and prefers mostly non-fiction).

  • BS, Virginia Commonwealth University
  • DPT, Health Sciences, University of Saint Augustine
  • Certified, Dry Needling, BLS, and Yoga instructor (200 hour)
  • MTC Certification (in progress)

What makes me unique:
My communication skills and ease with building a therapeutic alliance is one of the things that makes me unique.
I also have a great sense of humor and that allows me to form great relationships with my colleagues and patients alike. As someone who has traveled often and has lived in six different states, I am relatable and can discuss a variety of topics and experiences. My travels have also made me more empathetic towards a variety of social situations, understanding of different cultural beliefs, values, and customs, and these experiences have allowed me to form stronger relationships with my patients and colleagues.

Why do you practice healthcare:
Creating professional and interpersonal relationships is very important to me. There aren’t many career fields where you get to develop both simultaneously. Practicing as a physical therapist, you see people at their best and at their worst and it can be a very vulnerable state of transition for most. Maintaining professionalism, and striving towards achieving my patients’ goals while maintaining integrity and displaying empathy is something that comes naturally to me. The gratification that comes with success or, even failures as those are also learning lessons, is something very unique to the healthcare field and my experiences have allowed me to develop professionally as well as personally.
The knowledge, the experiences, the professional and personal growth that is possible from a career in healthcare is irreplaceable.

What makes me unique:
Ever since I was a child, my friends always sought me out for support or advice. It made me realize what this is what I am meant to do as a profession! My ability to put others at ease, make them feel comfortable, and make them laugh is unique. Coupled with my outgoing nature and love of helping others, being a clinical psychologist fits my personality well.

Why do I practice healthcare:
There is nothing more exciting to me than connecting with another person, regardless of any differences that may be present. I have worked in international settings where connection occurred and change happened.

Working with folks to uncover their own skills and potential keeps me actively engaged. I have always loved the applicability of this work; the fact that I can learn a new skill in a training or continuing education class and be able to apply it in a session, has always been a motivator for me. The opportunity to work on a team of providers has me excited for this wonderful opportunity!

Rachel Heatherly


Rachel has specialized training in working with folks with sexual health concerns, women’s issues, chronic pain and illness, anxiety, depression, and life adjustments.

She strives to create a warm, safe, empathetic, non-judgmental space and she believes it is important to process a person’s unique context and understand how intersectional identities and structures of oppression contribute to distress.

What makes me unique:
I am a digital artist who has a strong sense of humor and love of giving gifts. As a result, friends and family often receive a range of gifts: sometimes beautiful and thoughtful digital paintings of their pets or cartoons of themselves merged with a current pop trend or whatever I am watching on Netflix at the time.

Why do I practice healthcare:
For me, it is important that healthcare be accessible. During my years of service, I’ve seen first hand how many barriers (e.g. financial, transportation, time, mobility) can get in the way of receiving quality physical and mental health care. As a result, it is important for me to be a part of the solution. I enjoy how Crossover is reworking healthcare to be more accessible and equitable for its members.
